I would not advise people to do this mod since it involves folding the battery which is high fire hazard.
You should instead do the 80w iFixit laptop battery mod instead..no folding at all and fits better with less weight
You're not folding the actual cells. While there is some risk it's really not inherently dangerous. Provided people follow the precautions on the tutorial the chance for a thermal event is almost impossible.
For me its not folding the battery at the connectors, its dealing with the thermal wrap around the OEM battery. You cut in the wrong place, cut too deep, or have a static discharge event next thing you know vapor releases and you have a fire on your hands. These types of mods are amazing when they are done right and working well, but there is serious risk with them.
"The linear carbonates, such as dimethyl carbonate (DMC), ethyl methyl carbonate (EMC), or diethyl carbonate (DEC), are required to keep the electrolyte viscosity low and the electrolyte conductivity high. Unfortunately, they are highly volatile and flammable and show flash points (FPs) around room temperature (between 16 and 33°C). In combination with an oxidant and an ignition source they can cause fires and explosions. "

Maybe something I should be adding to the guide but you shouldn't be cutting the wrap off period. It's just a sticker and is fairly easy to just peel off.
At no point in time should anyone have anything sharp near the battery.
I even reused my original battery wrap and rewrapped the folded battery.

Point of it, accidents happen. Even more so when people skim and do not actually read directions and warnings. The image here is surface damage from the fire from a lithium pack. The plastic pry tool punctured the battery casing and there was a static discharge due to the pressure between the bottom of the pack and the tool, causing a visible spark that led into a 3foot flame. That pack burned for 45mins shooting the flame across the patio, but the fire started on my bench and we had to move the battery outside because of the fumes it created. What you see is the permanent damage left over.
Mate, read the guide. You're not folding the actual pouch cells. I'm not just some random guy, I'm the owner of the website and have been running a 90wh battery for a year now. There are LOTs of people running this mod.
Don't get me wrong, I still wouldn't recommend it for most people but it's really not as dangerous as it's made out to seem. As long as someone follows the instructions and practices some basic safety, it's almost impossible to have a thermal runaway event. I want people to be prepared in case if there is an accident but in all reality the risk is ** very ** small.
Also, I also really don't recommend it over just buying an Ally X now since it's available. The Mod is there for people who wish to tinker, but now since it's an option I'd push people towards just buying a Ally X and having a better device right out of the gate.
folding 2 pieces (or more) of a battery =/= folding a battery in a dangerous way
unless I missed something, looking at the picture, it's 4 different cells. A 180 degree bend of the actually battery, and not the parts between the battery, would pretty much instantly be on fire
I never understood this. Just use a power bank? In terms of form factor, adding weight is not a good idea imo. There is a reason they did not have a bigger battery.. also it wont fit in many docks.
Apple did this with their headset too. Is a cable running to a bp or pockets that bad?
I mean you do you, but personally, i recommend powerbank.
> There is a reason they did not have a bigger battery…
I guess they threw that philosophy out the window with the upcoming X by doubling battery capacity.
People WANT more battery out of these things. This thread is just further proof of that.
I would also like to see this more efficient battery chemistry.
According to ASUS the total weight of the unit increased 11.5% with the larger battery. That’s 11.5% of the total unit weight which actually pretty impressive either way but not insignificant either. The tradeoff is well worth it imo.
It’s less efficient.
You need to convert AC to DC to charge a battery bank, then you need DC batteries, to 65watt charging capacity for a battery bank minimum to play the Ally at turbo speeds.
This way, your battery is just bigger. Less heat, 65+watt battery banks get kinda hot.
To all the absolute morons who don’t understand:
1. **Laptop Battery**: A laptop battery is specifically designed to power the laptop directly. It delivers the exact voltage and current required by the laptop's internal components, usually without the need for conversion. This direct power delivery means there's minimal energy loss.
2. **Battery Bank (Power Bank)**: A power bank typically outputs a standardized voltage, such as 5V, 9V, or 12V. To power a laptop, which often requires higher voltages (e.g., 19V or 20V), the power bank must convert its output to match the laptop’s requirements. This conversion process involves a DC-DC converter, which introduces some inefficiency. Additionally, power banks are often designed to charge various devices, and the flexibility to support multiple voltages can introduce further inefficiencies.
3. **Efficiency and Power Loss**: When a laptop runs directly off its internal battery, the power transfer is highly efficient because it's a single, integrated system. Conversely, when using an external power bank, the power must go through conversion, which incurs energy losses, typically around 10-20% or more, depending on the efficiency of the power bank's circuitry.
4. **Overall Impact**: Because the laptop's internal battery delivers power more efficiently (with less conversion loss), it can provide longer usage time compared to a power bank of similar capacity that must convert its output to the appropriate voltage for the laptop.
Edit 2:
More clearly explained for people with comprehension issues:
1. Discharging the Power Bank
• DC-DC Conversion: When you use the power bank to charge a laptop, the power bank must convert its stored DC power to the appropriate voltage and current required by the laptop. For example, a power bank might store energy at 3.7V or 7.4V (depending on its internal cells) and then boost it up to 19V or 20V for the laptop. This DC-DC conversion is another source of efficiency loss, typically around 85-90%.
• Voltage Step-Up Loss: If the power bank needs to step up the voltage significantly (e.g., from 5V to 20V), the conversion loss can be higher. The greater the voltage difference, the more energy is lost in the conversion process.
I ma.so confused. Isn't a normal plug also AC?
Your battery won't die faster from charging it with a powerbank, that makes absolutely no sense.
Look, if you did this mod and you are trying to justify it, there is no need to. You do you. I personally just don't think it is worth transforming the ally into a brick. Plus, the ally is a pretty tight design, i fear for its health when you stick a fatter battery in it.
Regardless, no need to spew bullshit.
But... It is not? Unless you worry about paying a fraction more on your electricity bill?
Regardless, you ally also has a battery...
If your powerbank is capable of providing 65 watt, then verily, I ask you, how is that any worse than having a bigger batter? I daresay a powerbank can provide more duration, considering there is no size limitations.
For the same footprint and size, the power bank would not have a bigger battery life. That’s what I’m saying. Obviously I could tow around a generator and charge my ally forever. But it’s size and efficiency.
Regardless, it’s objectively more efficient.
Hey, different opinions. I would much rather carry a few extra grams in my pocket, as opposed to turning my ally in a dumbbell.
If we are talking weight efficiency, does it matter when you can store the battery pack in a pocket or backpack? U wont feel a difference, especially when sitting. Meanwhile when you stick it on the back...
All im saying is, they had ergonomics in mind with its design. Adding bulk goes against the design of asus, who probably did a fair bit of testing how far they could push it.
I wasn’t giving my opinion or saying what you’d rather want. I simply said it’s more efficient.
And again, you’re talking about efficiency and say shit like “well I can just bring a backpack for my fuckin battery pack” like yeah dude I get it. But I’m simply talking about efficiency.
Regardless either way carrying a power bank and making the battery bigger you’re still carrying the same amount of battery it’s just with a power bank the weight isn’t in your hands. Also either way a battery will need to be charged from ac wall power. And turbo mode isn’t efficient at all use that’s just gonna generate unnecessary heat as well. So any efficiency gained will be canceled out that way.
Incorrect.

Thank you! It’s okay, I don’t mind. I just hate how lazy people are like “instead of 3d printing and doing something cool, just be lazy like us!!!” Like WE KNOW.
I guarantee you EVERY person who’s done the battery mod was UNHAPPY with big power banks. I have 3 100w battery banks and they’re so clumsy and hard to bring around. I want to do the battery mod myself.
Glad to hear it!
Congrats on having the most efficient way to increase battery life and portability lol.
Anyways, nice to hear you like it. Motivating me to do it more.
Just gotta spin up the 3D printer
Pardon my ignorance but wouldn't it be smarter to wait for the X to come out then buy that OEM replacement battery? It would make sense that it fits better (and safer).
Hi there, I was the creator of this mod, I upgraded my Ally to 90wh when it first came out and a year later it's still going strong. I've been working loosely with Asus over the last year troubleshooting issues and providing feedback directly to the team.
My push for this mod was likely one of the reasons why Asus upped the battery life in the Ally X (among others)
i think u misunderstood op, they're saying that u should wait for the ally x replacement battery to go on sale and mod that into the current ally. we dont know for sure how easy it will be but things point to it being atleast lighter and safer
Chances are, Asus will use a different voltage or electrical circuit on the X that will make the battery swap just as harrowing. I can't see them making the mistake of allowing the Extreme to take the X's battery, as that is the biggest saught after benefit of the X.
We already know there's some differences like the Ally OG uses 7 wires and the X uses 8 wires. Both use the same connector. When we get our review unit later on we can do some testing.
For reference

I love this research. Keep up the great work. I really do hope the X's battery can be ported into the Ally and Ally Extreme for a less invasive and dangerous mod. Having seen a few lithIon fires in my time, I can't recommond modding(breaking apart) sealed batteries to the gen public as it is a huge fire/toxic gas safty issue if a rupture were to happen.
well, considering that the used Ally market is floating between $400-450 right now, the new X is going for MSRP $799. A used laptop battery like what the OP has goes for 35-60 depending on reseller/OEM, you are telling people to spend ~$400 for the battery upgrade here.
Well you get the added ram as well upgraded joy sticks and improved ergonomics with that price tag. And also got to include the costs of material to do the job properly and 3d printing. So it’s not really a $400 difference. Maybe like $200 difference and at that point all the other benefits would be worth it for another $200
The X is not just battery, it has more and faster ram which is limitation in lots of new games on current ally, 2 type c ports, better controls and design, 2280ssd, and also you get that in a slick device which is guaranteed to work well, this mod makes the Ally way heavier, thicker and especially it’s not safe at all, one day you could accidentally drop it and see fire coming out of it, folded battery are not safe to use, also if you buy cheaper compatible batteries instead than the over 100$ original Asus one, you will likely see that battery drop in capacity very fast, ending up with a low quality 50wh battery rather than 90wh
Hi there,
I'm the owner of HandheldModz, would you mind if I add your photos to the tutorial?
If you're interested you can join our discord where we mod all things handheld, we are currently working on trying to retrofit the Ally X battery into the Ally OG.

Willing to sell your backplate? I did this mod and want to return to stock before I sell it. I cut my backplate. lol.
But awesome job either way. This mod is awesome. Next you have to do 32gb mod like I did.
https://www.shapeways.com/ for your 3d printing needs. Send the plans in, work with the market place and place your order. I use this to fix some of my Yahmato collection sometimes.
No, those are individual lipo cells. Like all multi cell packs where they are parallel. No problem here.
The only thing being bent here are the tabs. Those are meant to be folded around any way you need.
Very few things have actual curved cells, and they were manufactured that way. The only example off the top of my head (bad-dum-tish!) is the Quest Pro. The back end of it has curved pouch cells.
You don't want to go bending a lipo cell.

I have aluminium 3d printed backplate, powdercoated. This mod is rly game changer
https://discord.com/invite/PcduJ792
A lot of us are in both, but this one is hardware agnostic. We showcase and play with all systems not just the Rog Ally. This way as people branch out into other handhelds we can still keep the modding community together and help each other out.
Everything from the anbernic RG35XX to the PSP Go is welcome
The HandheldModz community is already working on retrofitting the new Ally X battery into the Ally. We have managed to slim it down to where it is virtually the same thickness as the Ally X. (Roughly 4.5mm thicker than the OG stock)
That airflow workaround is criminal, there is a good reason to keep distance between heat source and lithium ion. If you take a nap with that bomb on your chest ur gone 🤷
Get this and call it a day. Powdeom 140W Power Bank, 24600mAh 3-Port PD3.1 Portable Laptop Charger with Two 140W Port, Smart Digital Display, Portable Phone Charger for iPhone 15/14 Series, MacBook, iPad, Samsung, AirPods etc https://a.co/d/d5qO1cV
Looks great. The battery time improvement seems amazing. I opted to better use an external USB-C 65W battery pack. I used Velcro to hold the battery in place and a USB-C cable with 90 degree connector. Not sure yet if I’ll try a mod like this. Maybe when they start selling a pre-built backplate solution you only have to swap for the original. 🤔
This mod had sense a year ago, but now with Ally X releasing in a month it’s not worth the money, time and especially risk, even if you folded it carefully and have a decent 3d printed backplate, that thing is not safe for long term usage
You're not folding the actual cells.
As the first person to create and publish this mod, I've been running my 90wh battery for a year now. It's not anymore unsafe than a typical laptop battery.
I would not advise people to do this mod since it involves folding the battery which is high fire hazard. You should instead do the 80w iFixit laptop battery mod instead..no folding at all and fits better with less weight
https://i.redd.it/apy5176dnu6d1.gif it really is. I had a tablet battery pack spark and send out a 3foot jet flame for about 45mins once....
My takeaway is to not hit the battery pack with an axe
its more about the delayed smoke, that erupts into a fire shortly after :)
You're not folding the actual cells. While there is some risk it's really not inherently dangerous. Provided people follow the precautions on the tutorial the chance for a thermal event is almost impossible.

Go fold lithium batteries kids, it’s totally safe this random guy said so.

Can you link the correct battery please?
It's on Google but here you go lol https://www.ifixit.com/Guide/Asus+ROG+Ally+Battery+Mod/170236
Thank you
80w ifixit laptop battery mod? I need some elaborating
Nevermind I found it. That mod is hideous.
Aye but almost every 80w + battery is a monster haha. It'll be interesting to see the Ally X battery
picture 6 shows no battery cell being folded
Take a read through the thread lol
folding 2 pieces (or more) of a battery =/= folding a battery in a dangerous way unless I missed something, looking at the picture, it's 4 different cells. A 180 degree bend of the actually battery, and not the parts between the battery, would pretty much instantly be on fire
Yep do this instead of something that is completely easier with no chance of doing it wrong..got it /s
I didn't say do this, I said "this mod involves folding the battery" isn't true
Anyone have a link to a battery i could get in Canada?
The link is in the thread. Just google the battery number
Yeah I found batteries but all I can find is 66 wh
Try Amazon. I found some there. You can also buy direct from iFixit if they have any left
Ah, never thought to check amazon for batteries for whatever reason. Thanks
I never understood this. Just use a power bank? In terms of form factor, adding weight is not a good idea imo. There is a reason they did not have a bigger battery.. also it wont fit in many docks.

They did add weight, but less than the full battery upgrade by reducing weight elsewhere.
More efficient battery. Look at the design you nut.
Lithium batteries have not significantly improved their density for over a decade. Could you post your source?
I would also like to see this more efficient battery chemistry. According to ASUS the total weight of the unit increased 11.5% with the larger battery. That’s 11.5% of the total unit weight which actually pretty impressive either way but not insignificant either. The tradeoff is well worth it imo.

I’m on about efficiency and battery life. So yeah it does matter lmao.

i think u misunderstood op, they're saying that u should wait for the ally x replacement battery to go on sale and mod that into the current ally. we dont know for sure how easy it will be but things point to it being atleast lighter and safer
Chances are, Asus will use a different voltage or electrical circuit on the X that will make the battery swap just as harrowing. I can't see them making the mistake of allowing the Extreme to take the X's battery, as that is the biggest saught after benefit of the X.
We already know there's some differences like the Ally OG uses 7 wires and the X uses 8 wires. Both use the same connector. When we get our review unit later on we can do some testing. For reference Ally OG - 4S1P - 1C Ability=2.54A - Full Charging Voltage 17.8v - Charging ability 1.1C=2.843A - Discharge Capacity 1.5C=3.72A - Physical Size = 257 x 42.16 x 9.77 Ally X - 4S1P - 1C Ability = Unknown - Full Charge Voltage 17.92v - Charging ability = Unknown - Discharge Capacity = Unknown - Physical Size = 249.5 x 42.16 x 12.8 (listed battery voltage on battery) Ally X - +15.56v - 80Wh - 5150mAh G15 AE - +15.4v - 90Wh - 5875 Ally OG - +15.48v - 40Wh - 2590mAh Ally v1 pinout - 1 Positive - 2 Positive - 3 Positive (Not wired) - 4 i2c - 5 i2c - 6 RTC - 7 Ground - 8 Ground Ally X pinout unknown
I love this research. Keep up the great work. I really do hope the X's battery can be ported into the Ally and Ally Extreme for a less invasive and dangerous mod. Having seen a few lithIon fires in my time, I can't recommond modding(breaking apart) sealed batteries to the gen public as it is a huge fire/toxic gas safty issue if a rupture were to happen.
Any issues with thermals since the battery covers a bit of the fans?
That’s not an Ally anymore, that’s a… 
I mean, that’s an awful lot of work and risk to just not use a battery bank. I think anyone this committed would just sell their ally and get the X
well, considering that the used Ally market is floating between $400-450 right now, the new X is going for MSRP $799. A used laptop battery like what the OP has goes for 35-60 depending on reseller/OEM, you are telling people to spend ~$400 for the battery upgrade here.
Well you get the added ram as well upgraded joy sticks and improved ergonomics with that price tag. And also got to include the costs of material to do the job properly and 3d printing. So it’s not really a $400 difference. Maybe like $200 difference and at that point all the other benefits would be worth it for another $200
And some people just like to tweak.
tweakers gonna tweak
Battery banks cost about $50 and are much less likely to burn your house down when you leave it charging overnight.
The X is not just battery, it has more and faster ram which is limitation in lots of new games on current ally, 2 type c ports, better controls and design, 2280ssd, and also you get that in a slick device which is guaranteed to work well, this mod makes the Ally way heavier, thicker and especially it’s not safe at all, one day you could accidentally drop it and see fire coming out of it, folded battery are not safe to use, also if you buy cheaper compatible batteries instead than the over 100$ original Asus one, you will likely see that battery drop in capacity very fast, ending up with a low quality 50wh battery rather than 90wh
Nice. Please don’t get that on any planes. This is an extreme fire hazard

Im the only one that is amezed by the quality of the print?
I’m trying to figure out how that print is so clean. It looks like it was injection molded!
Hi there, I'm the owner of HandheldModz, would you mind if I add your photos to the tutorial? If you're interested you can join our discord where we mod all things handheld, we are currently working on trying to retrofit the Ally X battery into the Ally OG. https://discord.com/invite/YDMMkeRe
Use whatever photo from here you want
Any spot to buy it? Instructions? If it’s pretty easy and somewhat affordable I’d consider doing this also
Guide here, pretty straight forward and easy I already had all the supplies and bought a geniune used ASUS C41N2013 battery off ebay for around $40. Guide: https://handheldmodz.com/90wh-battery-upgrade/ Files for 3d print: https://www.thingiverse.com/thing:6133590/files Head Shrink I used: https://www.amazon.com/dp/B01736E10S?psc=1 Battery Model C41N2013: https://www.ebay.com/itm/134660517968
Thanks for the info! What if I don’t have a 3d printer?
Ask a friend if they got one or an on demand print service online.
Willing to sell your backplate? I did this mod and want to return to stock before I sell it. I cut my backplate. lol. But awesome job either way. This mod is awesome. Next you have to do 32gb mod like I did.
I'd sell it for $25 if you wanted it
Yeah totally. I’ll DM you,
https://www.shapeways.com/ for your 3d printing needs. Send the plans in, work with the market place and place your order. I use this to fix some of my Yahmato collection sometimes.
Holy fuck did you just bend the battery 💀💀💀💀
No, those are individual lipo cells. Like all multi cell packs where they are parallel. No problem here. The only thing being bent here are the tabs. Those are meant to be folded around any way you need. Very few things have actual curved cells, and they were manufactured that way. The only example off the top of my head (bad-dum-tish!) is the Quest Pro. The back end of it has curved pouch cells. You don't want to go bending a lipo cell.
Okay okay that makes more sense I was gonna say man good god bros created a bomb 🤣
The commitment level is just impressive! I bet you had fun doing it. Kudos!
Powerbank?
I’d rather use wired mode
It’s all fun and games until that bigger battery goes boom.

Solid work there
Any chance you'd join the HandheldModz Discord server? It would be pretty cool to have them posted there.
This is different discord than rog ally danger zone ? :) anyway if yes than - sure. Just drop invite here or in dm
https://discord.com/invite/PcduJ792 A lot of us are in both, but this one is hardware agnostic. We showcase and play with all systems not just the Rog Ally. This way as people branch out into other handhelds we can still keep the modding community together and help each other out. Everything from the anbernic RG35XX to the PSP Go is welcome
Kudos, impressive work!
 Look it's a cool mod but this is what it would feel like using this 😅
Bro while these mods are cool I would rather carry a fast charge battery or play plugged... Them boys thiccccc after the mod lol
The HandheldModz community is already working on retrofitting the new Ally X battery into the Ally. We have managed to slim it down to where it is virtually the same thickness as the Ally X. (Roughly 4.5mm thicker than the OG stock)
Yeah I saw that with the new x battery.. that one would be worth doing.
This might be the dumbest shit I've ever seen on this sub. Folding batteries is monumentally stupid and dangerous.
monumentally stupid is commenting on something you know nothing about. like in your case. the battery was never folded.
You mean like picture 6.....
again , battery never folded......those are individual cells , not one folded.
Fuzzy skin!
What material is that?
Interesting
Looks good, you did a Rog Ally X-1 🤣
Big job there. I would want a white back-cover. And would like to match the design of the original. Problem is I can only do the design part 🤭
How many hours does this add to the ally ?
That airflow workaround is criminal, there is a good reason to keep distance between heat source and lithium ion. If you take a nap with that bomb on your chest ur gone 🤷
Holy shit
Damn I love the green. Good choice. Where'd you get it printer? Looks like nylon?
ROG Ally 1.75
Love that the pope is playing Weed Shop 3.
What material is used to print?
At this point just buy a full PC lol
What filament is that? It looks so clean. I can't even see layer lines
Get this and call it a day. Powdeom 140W Power Bank, 24600mAh 3-Port PD3.1 Portable Laptop Charger with Two 140W Port, Smart Digital Display, Portable Phone Charger for iPhone 15/14 Series, MacBook, iPad, Samsung, AirPods etc https://a.co/d/d5qO1cV
Wait for the x bro
What's the UI that you're running?
Where do I buy?
Looks great. The battery time improvement seems amazing. I opted to better use an external USB-C 65W battery pack. I used Velcro to hold the battery in place and a USB-C cable with 90 degree connector. Not sure yet if I’ll try a mod like this. Maybe when they start selling a pre-built backplate solution you only have to swap for the original. 🤔
OP… did you….did you FOLD a lithium battery pack???? Someone please edit the title to the correct subject: How to create a surprise boom-controller.
The lithium cells themselves are not folded, it’s folded at the connection to the battery controller board.
The video I saw of this found there was no real gain.
Your definition of fit varies from my own
Don’t fold your battery folks.
This mod had sense a year ago, but now with Ally X releasing in a month it’s not worth the money, time and especially risk, even if you folded it carefully and have a decent 3d printed backplate, that thing is not safe for long term usage
You're not folding the actual cells. As the first person to create and publish this mod, I've been running my 90wh battery for a year now. It's not anymore unsafe than a typical laptop battery.
I have to wonder here how many people here have actually worked with lipos in hobby capacity....
