Puffed = ?

I have a puffed TP2070, it charged to 12.60v. What does the puff mean? Less power, shorter life, no good ??? Can i still use it, and get the same power during flights? :?:

Well if it puffs the cell chemistry has changed. Something has released a gas, and it won't ever be the same again.

Personally I wouldn't use it. Odds are it's more volatile now, either because of the gas or whatever it has left behind.

They are at risk for fire when they are puffed.

If you use it, be VERY careful. Charge in a safe place, watch it carefully when flying, and remove it from the heli as soon as you land.

Thanks. Tunder Power said they will replace them for $45, Thats better than $80 new. No more 315 blades on 450, thats where I went wrong, back to 325 blades.

What went wrong with the 315 blades?

I dont know, 315s arn't made for 3D. I never had a problem till the change.
