Charge 4 Lithium Ion Batteries in series? Answered
I have got 4 3.7v 6000mAh lithium ion batteries connected in series with 2 batteries holders. I would like to charge them without taking them out (prefer to seal a unit). Anyone know how to do this (I could connect the 4 "cells" individually to separate input/outputs.)?
Also have 19v 3.16A power supply available to use also for charging (Batteries are for making it portable and plug for the 19v)
