Guys.. I am a little confused..

When you use your LIPO do you run the car till the battery dies? Or do you stop prior? Reason for me asking is this explanation below?

The other thing that will heat a pack up fast is if you push it right down to or lower than 3.0 volts per cell under load. Even if you have a 40C pack and can only draw half that amount, if you push it hard right down to 3 volts per cell - it will become very warm/hot and will shorten its life substantially.
