Yes, but you also would want a decent charger to keep the lead acid batt topped up. As well, you would need a 12v battery in the first place, if not, you are paying at least $100 for a good deep cycle lead acid, at least I would want a deep cycle batt for that.
It's a fast way to charge at the very least though, and I don't know of a programmable power supply that can deliver 20 amps and charge 3s for under $200.
