My lithium pack has expanded, swelled, or warped and I don't know why! I was injured and bedridden for a few months and unfortunately the cart sat for almost 3 months. During that time, my pack came pretty close to discharging completely (I know this is bad).
Does anyone know if a total discharge would cause the warping or swelling of the cells to happen? As you can see in the picture, it even bent the frame! The only other info I can give is that the cart was outside the whole time under a carport. We had a pretty cold winter, but never too far below freezing. The battery is in a dry box in my cart, so it was completely dry and there was no direct contact with the cold weather or other elements.
Note: This is a Nissan Leaf 48v Lithium pack that I purchased from EVBatteryCenter a few years back. I have asked them about it and I haven't gotten a direct answer back yet. Any help would be greatly appreciated! I'm assuming it is not safe to try to do a trickle charge and power back into it?
