You may not have done this, but make sure you NEVER leave your batteries plugged in with a brushless ESC - they suck juice even when turned off an can ruin a fully-charged lipo in as little as 24 hours.

i always unplug them so that could not have done it

Were you using the lipo cutoff on the ESC? If not the previous outing may have over discharged one or both cells. At any rate; that is not good being swelled. Maybe got it wet? There are a lot of variables

your gonna want to do some research on "Properly Discharging and Disposing Lipo Batteries"...

 

[JimmyG]

You need to give full details on when you used, was it charged after use, etc. Need every little detail, but yes, if its swollen...get a new one.

okay yea i actually took extreamely good care of it i even gave it a storage charger 10 mins after use
