CORRECTION at the 4 minute 30 second mark I say that the current is being shared between the cells. It is not being shared and each cell receives the full current. Sorry for the mistake.

I test a BMS and what happens when applying voltage through a BMS into a 3 cell lithium ion 18650 battery pack connected in series. This can give a nice rechargeable 12v battery pack but does the BMS recharge the lithium batteries properly and safely?
