If you're hammering a battery with a 40-amp discharge/charge cycle to heat it up and drop the
impedance to get better performance you're probably not overly concerned with the life of your batteries. I believe there's also a rule that your battery has to be within a few degrees of the ambient temperature of where you are racing. I'd also prefer someone use an iCharger to cycle their batteries than sticking a battery in a toaster oven.
Note: Most of the crazy charge/discharge and heating of batteries is for stock racing. If you're racing mod, then just get a decent charger that will charge your batteries. Although, an iCharger is nice to have as it does a good job of showing you the stats of your batteries and helps with maintaining the health of your battery.
