What charger do I need for a 72V battery?

A standard 72V 20S lithium-ion battery typically requires an 84V charger.

Can I adjust the charger voltage?

The supplied specifications state that certain HRH300 models have internal voltage and current adjustment potentiometers. Opening the charger is required, so adjustments should only be performed by a qualified person.

Can this charger be used as a power supply?

The supplier states that the charger can directly output voltage and current for use as an adapter. However, output configuration and electrical requirements should be verified before using it for applications other than battery charging.

Does the OLED display measure accurately?

The supplier states that the display parameters have approximately a 10% operating reference tolerance. Use the display primarily as a charging-status/monitoring indicator.

⚠️ Important Ordering Notice

Do not choose your charger based solely on the nominal battery voltage.

Verify your battery's:

Voltage • Full-Charge Voltage • Chemistry • Charging Current • Connector • Polarity

If you're unsure which charger you need, check your battery label for the required voltage and charger specifications before ordering.
