You can't beat a smart charger designed for SLA batteries with a max output current of 6 amps per output. There are a few that have five or six outputs of five amps each that work fine. Smart chargers will modify the output current throughout the charge cycle and will automatically stop the charge cycle or switch to a low trickle when fully charged.

Please remember that although the charger is only able to supply 6 amps, the battery that it is connected to has the ability to supply more than 500 amps when charged. That potential is available at any improperly insulated connections that you supply on the charger side. This is a common mistake that teams make. It is also the reason for the rule this year because burning wires have resulted in the past.
