i had the balance tap wire break which is common with taps that have a stiff wire as many of you already know.
when i opened the lipo up it had pits in it from a small rock rolling around in between the hard case and the lipo itself
i did not even think to seal the ends when i brought them
any how heres a pic for comparison to other lipos
just note its says its 4000ah 25c but all these lipos where labeled wrong from the factory and are 3600ah 20c lipos
