So over the off season we plan to develop a battery charging cart that will charge the battery at 2 Amps for a while, then 4 Amps, and then 6 Amps to get our batteries at full complicity and keep them living longer. Does anyone have any ideas on how we can make this possible?

Charging a battery to 15v will not make it last longer, it is the other way around. The 6 amp charger will go green at 13v but will charge up to 14.6 if you leave it to maintain the battery. The best way to charge a battery is by charging the battery at 6 amps then slowly lowering the amperage as it gets closer to a full charge.
If you want to charge to 15v every time get one of these (
