How durable are the p2 batteries?

[max01726]

accidently dropped my p2 battery this morning when removing it... just wondering how durable they are... cant see any damage and it still charges and indicates battery level fine. just don't want to take it for a fly and the battery shut off!
cheers

If you can't see any physical damage it's likely fine. Just keep an eye on it when charging and make sure it doesn't start to bulge.
