Schumacher battery charger. I don't run an alternator, so I need to charge batteries between rounds. I set it on 20 amps and charge+ run water pump&fan at the same time.
Lots of guys say you shouldn't do it that way, you should use a 2nd charger or spare battery to run the fan/pump. I will probably wire in a disconnect this off season and bring a smaller charger with me to the track. I have several in the garage.
