Powerwise 36 Volt Battery Charger Manual __link__
108–125 Volts AC, 60 Hz, single-phase, drawing approximately 10.5 amps.
As referenced in any PowerWise 36 volt battery charger manual , these chargers rely on the specific state of the batteries to regulate the charging current. This is a crucial concept: the charger is "dumb," but the battery pack is "smart." The charger will only output its maximum amperage if the batteries are significantly discharged. As the batteries fill up, their internal resistance rises, automatically forcing the charger to lower its output. This prevents overcharging without the need for complex digital timers. powerwise 36 volt battery charger manual
