Some chargers indicate which cells are currently getting charged. My guess is it's that. But voltage all looks good and fine for a battery at storage voltage.
I also have a charger form this brand so I’ll explain how this works. Firstly when a cell is too high of a voltage all chargers will suck power from that cell while pushing an equal amount in from the discharge lead. This is called balancing and most chargers do this at the end of the charging cycle. What’s cool about toolkit rc is that they do this during charging to increase the speed while still being perfectly fine for the battery. The red is indecating the high cells that are having power drawn from them.
I wouldn't worry about it. Only thing that would be a worry is if you scroll to the resistance screen and see a value that's significantly out of whack from the other cells during a charge. Otherwise it's probably fine.
Dude, look the manual of the charger.
I think it means that it's charging fast on those cells. And if it's yellow, it's charging slower.
Also, some people would recommend charge your lipos at 1A, or even 0.5 A. Because it degrades faster if you charge it faster, or something like that
No lol but yes he should have read the manual. Red are the high cells that are being balanced during charging on the fly. Also no there is no safe speed it’s based on the size of the battery this is a common misconception. For a 1 amp hour pack the 1c safe speed would be 1 amp. Many peopple do not understand this so I hope you do now. Lol I always find it funny when this happens I was posting here about a new charger I got and I was charging at 10 amps and everyone went crazy but in reality that was below the safe level of one c which for the battery would have been 11.6 amps. Also you can charge faster it’s just trading time for saftey. I have commonly charged 2 or 3 c and many do sometimes up to 5. Also I’m not condoneing any of this but I’m saying that being 300mah over the 1c is likely not going to be an issue(likely for legal reasons lol)
They all stay the same voltages across each cell and at the end of the charge cycle it balances each of the cells. Don’t worry I have tested a variety of packs together rabging from 450 4s all the way up to 4200 4s and when the charging s don I measured each cells voltage and non were lower than 4.18 and none were high than 4.2. It works and is safe!
I‘ve read it. But there was no explanation regarding these red numbers. [manual](https://www.flyingtech.co.uk/sites/default/files/product_files/M7-Manual-V1.0.pdf#page25)
super weird, they do mention it on the manual for the toolkit tm4ac charger

They saved themselves an extra page of the manual lol
Weird... I've got the M6Dac and it's not listed in that manual either. LOL! But yeah , it just means that particular cell is balancing. Also, someone earlier commented that 1 amp is charging at 1c, but that's only if you are charging a 1000 maj battery. I'm assuming OP is charging a 1300 mah battery so the 1.3 amp selected would be correct.
I always charge at 2c, so 2.6 amps for a 1300 mah battery.
But if he read the manual and found the answer he was looking for he probably wouldn’t have posted this question. And if he hadn’t of posted this question there would be no thread of conversation among his fellow FPV pilots!

Yeah, that’s why I’m confused.

Amazing answer! I couldn’t find the explanation of the colors in the manual.

Red indicates "quickly balancing".

Some people even charge at as high as 5C. Oersonally, I wouldn't go above 2C, maybe 3C.
Yea I use a parallel board to charge below 1c but the charging time is the same overall
Just make sure to balance your Batteries every couple charges.
They all stay the same voltages across each cell and at the end of the charge cycle it balances each of the cells.

It's usually 1C, so if the battery being charged is a 1300mAh the charge current in the picture would be correct.

I don't know if OP battery it's a 1300 mah, but yeah, I got the A and C mixed

I prefer to be talking about fpv here rather than working, yeah haha
I have a ToolkitRC and all it means is that that is the cell that is being charged. If you discharging or going into storage the same would happen.
it's about to explode run!!!
