Choose the Correct Voltage

Battery voltage and charger output must match your bike's electrical system.

48V lithium-ion battery: Typically uses a 54.6V full-charge charger.
52V lithium-ion battery: Typically uses a 58.8V full-charge charger.

The supplier also lists a 42V charger, which is typically used for a 36V lithium-ion battery. Confirm the exact battery variant and charger compatibility before connecting or purchasing a charger.

Compatibility Guide

This battery is advertised as compatible with selected Ridstar Q20 Pro, Quercus, Sequoia, Pinus, and step-through e-bike models. Compatibility is not guaranteed across every model year or configuration.

Before ordering, check:

Voltage: Match your bike's original battery voltage.
Dimensions: Compare the listed 367.5 × 122 × 95 mm dimensions with your battery compartment and mounting rail.
Connector and polarity: Ensure the electrical connector matches exactly.
Current requirements: Confirm the battery's continuous current rating is suitable for your controller.
Mounting style: Verify the down-tube rail and locking arrangement.
Charger: Use only a charger rated for the selected battery voltage and chemistry.

A battery that physically fits may still be electrically incompatible with your bike.

Why Choose a Replacement eBike Battery?

A correctly matched replacement battery can help restore riding range and everyday usability when an original battery loses capacity. Actual range depends on battery condition, motor power, rider weight, terrain, temperature, tire pressure, and riding style.
