I know a guy in the Dutch nationals who has more wires going to his lipo bag than only for charging. Because with charging there can be heat we have a rule that at the start of a race the battery may not have a higher temperature than 10 degrees C above the ambient temperature. This guy has a tire warmer in his lipo bag and heats his batteries to that temperature although external heating as internal by high amps charging and discharging is not allowed.
If I was a race director and would see that I would send him home.
