/diy/ - Do It Yourself

>>1895554

dont use your bench supply unless you have a smart one that you can program to go from constant voltage to constant current at some given voltage. measure between + and - terminals, if it's around 3.7V you can use any old charger, like from a camera battery that puts out 4V. just connect the plus and minus pins and ignore all the rest. you can get these for a buck at the thrift store.

if it's 7.2V or higher, you need a more sophisticated Lipo charger with buttons and a screen to set things up. often these will detect the voltage and set themselves up accordingly.
