Today my 48v 15Ah LiFePO4 ebike battery fell off from my bicycle and got a little bit of road rash on the corner:
It still works. Does not seem to be heating or discharging on its own.
However, between battery minus and a tiny bit of the exposed area (not all exposed area in the picture is metal though) there seem to be +2V, which is making me somewhat nervous.
What would happen if I would simply apply liquid electrical tape on that area and call it a day?
Thoughts going on in my head:
- Could internal short happen and battery catch on uncontrolled fire?
- Does LiFePO4 chemistry play any role in this as well and add to the safety?
- I don't know what form factor cells are inside the battery pack and if that plays any role as well. Obviously dont seem to be anything durable like 18650.
- Should I simply throw away this battery and get a new one?
P.S. since its Halloween I am up to hear all horror stories on what may happen...
