Product Highlights:

  • One is enough>> Designed to charge 12V,24V, 36V, 48V, 60V, 72V batteries pack. Now you only need one charger to charge different batteries like SLA, AGM, GEL, LiFePO4, lithium, deep cycle battery. It can be used to charge car, motorcycle, vehicle, RV, ATV, SUV, Golf Cart, Marine, Boat.
  • Two charging modes>> Normal mode and “H” mode(pulse of high-voltage). Normal mode for daily charging, turn the AMPERE knob to set the charging rate, “HIGH” for an emergency quick charge. “H” mode for battery maintenance, “LOW” rate charging is recommended.
  • Choose right voltage>> Be sure to choose the corresponding voltage to charge your batteries. For example, when charging 36V batteries, please turn the knob to the “36V” position, and the charging voltage is 44.1V. But if you turn the knob to “48V” by mistake, the charger will not output amps after a while to avoid damage to the batteries.
  • What is “H” mode>> “H” mode is also an EQUALIZING CHARGE mode, which not only restores lost battery performance but also compensates for the balance between batteries and extends battery life. Turn the voltage knob to the “H” position, and set the current to the lowest. Charge your lead-acid battery slowly at high voltage, which removes lead sulfate and reverses acid stratification more efficiently.
  • Connect it& Forget it>> Overload circuit breaker and automatic control chip give you full protection. Just plug it, charging your batteries 24/7 without worry.
  • More power: Compared to model C20, the 60V 72V voltage level is added and the charging current is increased.12V-16A(max), 24V-14A(max), 36V-12A(max), 48V-10A(max), 60V-8A(max), 72V-6A(max)
