Ok, 1st mileage test complete---75.41 miles on flat roads ---stopped test @ throttle red light---batteries discharged to 22.18 volts---checked battery voltage w/ 10 seconds of stopping---batteries on charger now. Is this too low of a discharge state? What is the safe discharge level?
(edit)The recommended end-of-discharge voltage for the SLA is 1.75V/cell. Unlike the preferred flat discharge curve of the NiCd, the SLA has a gradual voltage drop with a rapid drop towards the end of discharge (see Figure 5-1).
