❓ Frequently Asked Questions

What types of 48V batteries can this charger work with?

This charger is compatible with all 48V Lead-Acid battery varieties, including Sealed Lead Acid (SLA), AGM, VRLA, and GEL batteries with capacities between 100Ah and 200Ah.

How does the automatic charging process work?

The charger uses a 3-stage process (Constant Current, High Constant Voltage, and Low Constant Voltage/Float) controlled by an MCU to ensure the battery is charged quickly and then maintained safely once full.

What are the safety features included?

The unit includes comprehensive protections: over current, over voltage, short circuit, reverse polarity, anti-revert current, and anti-spark protection to ensure safe operation under various conditions.

What should I do if the LED indicator flashes red?

A red flashing LED indicates a "Charge Error." Please check if the battery polarity is correct, ensure there is no short circuit, and verify that the battery voltage matches the charger's requirements.

Is this charger suitable for high-vibration environments?

Yes, the charger is built to the SAEJ1378 Standard for shock and vibration, making it durable for portable use and demanding industrial applications.

Can I get a custom output connector for my equipment?

The charger supports a wide variety of output connectors, including Waterproof plugs, Crocodile Clips, Aviation Connectors, XLR, Ring terminals, and Anderson Connectors. Customization is available upon request.
