By the way you do not PUMP current into batteries. The battery will determine how much current it wants to draw based on how much DC VOLTAGE is being applied.
If you have 15VDC available it will want to draw more current but may boil out your fluids.
It has been determined the best DC VOLTAGE for deep cycle batteries is 14.4 or so allowing the batteries to demand around 17-20AMPS of DC current to do it's charge cycle and not boil out battery fluids. You can have a 200AMPS BATTERY Supply connected to the battery but if you hit it with 14.4VDC it will only draw around 17AMPS DC Current of the 200AMPS that is sitting there...
The idea of having alot of DC CURRENT available to be used is so you can re-charge multiple batteries at the same time...
Just my layman two cents worth
