A 2S voltage cut-off of 3.6 would be safe and this is usually set through your speed control.

That is 3.6v per cell, so if you've drained your 2S pack to only 5v then you may have done some damage already.

since were on the subject of 2 cel lipo's... what is the main reason lipo's start to puff ? I get a puff battery at least 3 times a year and I never over charge... I use a Orion Clubman charger... I never run my batteries down very low.... I store my batteries after a 5 or 6 minute race for the week... I do have a bad habit of leaving batteries plugged in while still in the car for the week but never on... when I charge the night before a race they never are drained low... I keep them all in room temperature... am I doing something wrong or is this puffing thing normal ? this has happened with very expensive batteries to normal priced ones from all different brands...

I've noticed that the easiest way to puff a lipo is to leave it hanging around fully charged. I always run my batteries down before I store them away if I know it'll be a few days before I run them again.

And to the OP, yea your lipo battery is probably jacked now.
