I am using a LiPo battery to power a model helicopter.
After my first flight with it i noticed a yellow discoloration around the seam of one of the cells. The battery isn't puffed up.
The voltages for the cells are the following:
- 3.844 V
- 3.845 V
- 3.825 V
- 3.843V
Is it still safe to charge and fly this battery?
EDIT: I did charge the battery again and flew it and it worked. But i would still like to figure out what that stuff is and why it seems to be leaking out.
