Why not just parallell them for a while? Voltage should be equal on all cells then. Notice that you MUST disconnect the series connection first!

Well for one its a PITA since he's already installed the pack.....

its much easier to put a single cell charger on each one for a little while and do it that way.



As far as isolated chargers, you really only need one if you're using multiple chargers at the same time.

Ok, that is true (but still for free).

Could someone explain why switching chargers are necessary?
