Not on the chargers they have - 20A is the most an LRP will do! I was talking about the 40A merchants, and the top drivers I know don't have equipment to go to 40A. 10A is 1.5C these days for our cells, so hardly in the realms of the 40A merchants doing it to raise cell temp for best performance.
If you feel their cells before they race, they are room temp, so not getting any advantage from a warm cell to lower IR, etc. I know some discharge, but not at 40A which is where you get the real advantage... or so people think...
