    How much damage is too much for a lipo?

    I accidentally landed upside at full throttle. Oops.

    This is what it looks like. It looks worse in the photo than real life.

    Is this safe to use? I already killed one battery I hope this is not the second!

    Thank you.

    Doesn't look too bad... I used worse


    Do a couple of bench flights at full throttle and if it passes muster I say use it like normal. Unless your operating where a failure could be catastrophic in terms of crash and burn/ crash and hit expensive things I wouldn't worry too much.


    Oh, and keep an eye on it during the balance charges between your bench/test flights just to make sure it charges normal.

    Some good suggestions, I go with the "How much do you like this aeroplane guide?" That works for me

    If I have any doubts about the integrity of a pack, there's no way I could feel 100% about sending a >$1000 fully loaded FPV bird out a few miles with it. It joins the GS power club.

    No prob using it in a beater park flyer, or a ground pounder too. I have several old and damaged 5000 3S packs powering my fleet of RC trailing trucks.

    I dropped a new 3S 5000 on the parking lot ground after its first flight. Dinged the corner of one of the cells. Way less severe than what you have. No big deal, but I still never flew it again. Just anal of me I guess.

    No that's called using your head versus draining your wallet or worse.

    The cost of a new battery is minimal when compared to the loss a damaged one might cause.

    For something sitting on the ground it's not such a big deal, more of an annoyance than anything, but if it fly's it has to be 100% correct or no takeoff, I have read too many woeful tales of hobby pilots who have taken large losses due to failing to complete a preflight check-list.

    Have to agree with Wayne and Pushjerk. I discard damaged batteries. What I am most worried about is my plane or house burning. Think about a lipo going off inside a large foam plane in mid flight. It doesn't take a lot of imagination…….
