so the other day i dropped my megalodon on a concrete floor , while no damage occured to the pv itself when i tried to use it the dc carto tank i was using on it didnt fire so i threaded it off and back on again and fired right up . problem solved or so i thought , within the next few minuted i noticed my megalodon started feeling warmer and warmer , panic was starting to set in that the battery was going to pop . I quickly removed the battery took it oustide and left it for a half hour or so to make sure all was well . well it did cool down and unfortunately it was the only battery i had on me so i decided to give it another shot (yeah i know not the brightest thing to do but oh well) , so i switched out the cart tank for another and everything went like normal until later that evening when i tried the dropped carto tank and the battery started overheating once again; the battery is an imr 18350 . would it be best to just toss it or is the battery still good since it was the dropped carto at fault
