Set up:
Losi XXX-CR
Mamba Max 7700
Orion 3200 2S Hard case lipo
86t spur
19t pinion
normal timing
throttle curve gradual for easier start
motor barely warm
ESC about 165 or so at fins but bottom barely warm.

If a hard cased lipo swells up enough to bust the battery strap off and get hot during use is it usable again after its cooled down and when back to normal size? Safe to use? Even now (4 days later) its sitting at 7.29v and i havent done a thing to it since it happened

Im running a Mamba Max 7700 system and the first time running it there was no issues....same battery and a few adjustment that shouldnt have mattered later (drag brake, throttle curve..etc.)....and then it swelled up like that. its a 2S like castle says I can use but Im told it could be cause the 7700 is turning too many RPM's and is discharging the battery too fast. Any thoughts? I cant see the company saying its ok to use a 2S battery if it wasnt at the cost of those batteries.
