I’m running two 3s 11.1v 5000mah batteries in serial, and for the first part I was charging each one individually, because I don’t yet have a 2 x 3s > 6s balance lead adapter, then I got lazy and just started charging it in series with no balance leads! Now both my middle sells are at 0.00v and they won’t charge up! Is there anything I can do or are they a gonner?
Thanks for your help. I think I’ve learnt a valuable lesson here
