- One is enough>> Not just for charging 12V 24V batteries, but also as a 36V 48V battery charger. Now you only need one charger to charge different batteries like SLA, AGM, GEL, lithium, LiFePO4, deep cycle battery. It can be used to charge car, motorcycle, vehicle, RV, ATV, SUV, Golf Cart, forklift, 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.
- Intelligent charging program>> Be sure to choose the corresponding voltage to charge your batteries. The charger will automatically adjust the charging voltage and current according to the battery status. Constant current, constant voltage power supply for zero voltage charging for troubleshooting low voltage batteries or equalizing unbalanced battery system for longer battery life.
- What is "H" mode>> "H" means pulse of high-voltage, A golf cart usually comes with 4 to 8 batteries. One of them can go bad at any time. It makes sense to want to keep or change just the bad one especially if you only need to use the cart on the weekends or save money. That's what "H" does,also known as EQUALIZING CHARGE
- 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. Please do not connect lithium LiFePO4 batteries without a BMS to the charger for a long time.
- Adjustable output voltage range from 1.25V to 37V continuously adjustable.
- With voltmeter display, voltmeter error ± 0.1V, range 0 ~ 45V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4V)
- Touch the button to switch the measurement input or output voltage, and there is an indicator to indicate which voltage is being measured, and keep the last setting, even if it is powered off and then on.
- With terminal block, it can be easily used without soldering, and the wire bond point is retained.
- The voltmeter can be turned off. When not needed, the jumper cap of P3 can be removed to provide reverse connection protection, and the reverse will not burn.
