I think I fried my battery. Any help?

I have a 10s4p Samsung 30q pack(with BMS) that I only used once then I stored it for a few months. Today while rigging the positive/negative charging terminals I accidentally shorted it for a split second. I didn’t see any smoke and visually the pack looked fine.

Then I took it out for a ride. The battery got down to 92% then dead to 0%. I had to push the board back. When I got home it showed 92% again.

I don’t think it was a loose connection because the battery meter was still on showing 0%. I’m thinking that maybe because I shorted it the battery will die when it’s under load after a while?

are you just going off a battery meter? or have u used a multimeter? id start with a multimeter and check the leads? could be the bms…could be more…

You gotta be more specific. Energy doesn’t just disappear.

Don’t freak out! Dead BMS. BMSs don’t tolerate shorts! But also search for ripped solder or weld-joint (Could also be a cause).
