[RE-wrenches] Magnum System - Discharged Battery Bank

[Jay Peltz]

I find it really curious. 
I've been dealing with batteries for almost 20 yrs. I've seen so many dead, flat batteries, systems etc I can't count them all. 
But I've yet to find a reversed one. 
I understand the process. 

I'm trying to understand how he could get multiple reversed batteries at one go?
