I want to build 6s4p 18650 pack. I will not use bms. I will using imax b6 to charge it with balance port. So I need help to soldering 6s4p pack with those balancing wires. A diagram would be great
A balance charger for 6s is fine. It is not complicated. First connect all your 4 parallel cells together to make a larger battery from your 4 small batteries and then wire them like it is shown here.
Just take precautions not to over charge your cells, or mishandle them in other ways because improperly handled lithium batteries can burn your house down.
Edit: Also do not over discharge the batteries beyond manufacturers recommendations or you will ruin your pack.
