Uh oh....should I keep using this battery?

Had a little accident today. Took two hands to pull the motor out of the ground. Unfortunately the battery followed the motor in. The lipo bag is unpunctured, but being fairly new to electric flight, I am not sure if this is still safe. Any thoughts?

You may hear or read stories of people who have successfully re-wrapped and flown damaged batteries that haven't puffed.

But, personally, I wouldn't trust it in my model, or home, or car. The damage it has sustained, even if it still seems to be working okay, significantly increases the risk of it failing catastrophically without warning. I would discharge it somewhere safe (I left mine in the garden for a couple of weeks after a similar incident) and then dispose of it.

I've flown and continued to use Lipo's in worst condition but Abenn is absolutely correct, you are taking a chance. If you decide to keep it, just take extra precaution.
