The BMS will burn up excess current to the cells which are fully charged, allowing the remaining cells to get topped off. Eventually, this results in a perfectly top balanced pack.
So that figures! but can someone give me an idiots guide to a question regarding my G-Wiz (leads) it charges & when fully charged it runs! occasionally it equalises.
Whats the difference between charging & equalising?
If I converted to lithium do the same principles apply? as I know a BMS is an absolute must with them!
