Default Re: Voltage when charging?

64v = 3.55 v per cell = 10.66 v per 6/8v battery
This is the final equalization phase of the charging algorithm (pattern)
Equalization is essentially a controlled over charge.
Higher capacity wet (flooded) batteries benefit from this procedure, particularly the physically tall golf cart batteries. The electrolyte in a wet battery can stratify over time, if not cycled occasionally.
In equalization, the voltage is brought up above typical peak charging voltage (to 11 to 12 volts in a 8 volt system) well into the gassing stage, and held for a fixed (but limited) period.
This stirs up the chemistry in the entire battery, "equalizing" the strength of the electrolyte, and knocking off any loose sulphation that may be on the battery plates.
