How many batteries are needed to insure that a Progressive Dynamics PD4655V (55 amp using 4g wires) will go into boost mode when the batteries are at 50% SOC?
A 55amp charger will start to taper from constant 55 amps at 72% SOC on a 220AH bank at 14v. 72% of 220 is 158, but the PD goes to 14.4, so add a bit, so my est is 170ish. However it will taper right away.
With a Charge Wizard answer is, one battery. :)
