Quick battery question - i have two 4s batteries wired in series (soldered together). I Also have a 4s Lipo charger. What would happen if i tried to charge just one of the batteries using a 4s JST?
I had a 4S parallel balancing lead from HobbyKing i.e 2 4s JST connectors -> 1 4s connector, didn’t think it through and obviously got a big old spark as soon as i connected the batteries.
Whats the best way to approach charging these batteries? I’d liket to be able to charge them both with the 4s charger if possible.
