Bought a 12s4p battery from bimmer about a year and a half ago. After the first one he sent me short circuited in the mail, the second one seemed fine. A couple months pass and the battery stops working. I open it up and spot welds are falling apart, and half the batteries are corroded.
Looking to buy a new battery! Single stacked and any size. If you can build a battery for me, I can send you the (few) working 30q cells from my last battery.
