    Per battery voltages range from 6.27 to 6.34.   SG ranges from 1.265 to 1.275.   Battery Manufacturer says 1.275 is full charge.   After multiple charging cycles, some batteries/cells go no higher than 1.265.   When I set controller for equalize, 59.2 volts, the charger goes up to 58.4 volts and the amps level off at around 8 amps then goes no higher.   After four hours I terminate the equalize.
