HELP!! Battery Mod gone bad?!
 

ok so i installed my new 150 mah battery and then i charged it 3 times and at the end of the 3rd it started to make a sizzliing sound! wtf happened?! It wont move for more than like 5 seconds.... any help would be GREATLY appreciated since i just got my brang new auto modellista set and i am doing this on my new boost chassis! please help!!!!

I did the same thing. I asked "WTFH" too. If I were you i would get a new battery.I also have a tip. never put a soldering gun on the floor without wearing shoes.

what if i reversed the battery could it possibly be because the ends are mixed up?

probably what went wrong.
