To=20 have a consistent 24-28 vdc output for a useful length of time, as = I=20 suspect would be required for a bench test setup, you would need a power = supply=20 with close to 40 or 50 A output to maintain the batteries = state of=20 charge. If that is the case, why bother with the batteries. = Check on=20 E-Bay
