Hello all. New member, thanks for having me. I'm an FPV drone hobbyist and I'm in the process of making a 100aH battery to take out to the field when I spend hours flying. The battery will power the charger that charges my drone batteries so I can stay in the air.
I'm currently using an old car battery.
I purchased 4 Liitokala 3.2v 100aH cells off AliExpress a year ago and only started using them recently. I've wired them up as a 4 cell battery with a balance lead and am charging them off a SkyRC hobby charger at 100w charge. It should take over 12 hours to charge considering I have 1280 watt hours. I am using the LiFePO4 charge profile setting on the charger
Instead, the batteries get to 3.32 - 3.33v per cell after about 5 hours of charging, the charger says it's at "57%" charge and it just sits there apparently charging at 100w but nothing is happening. Even after hours, the cells are not going over 3.33v per cell.
Are my batteries no good? Or do I need a more advanced charger with a customizable LiFePO4 profile.
Regards
Kris
