Product Specifications

Availability of each capacity at each voltage must be confirmed. Specifications may vary between battery configurations.

Available Voltage Options

36V E-Bike Battery

The 36V option typically requires a compatible 42V full-charge lithium-ion charger. Confirm that your controller is designed for a 36V battery system.

48V E-Bike Battery

The 48V option typically requires a compatible 54.6V full-charge lithium-ion charger. Check the controller's supported voltage and current requirements before installation.

52V E-Bike Battery

The 52V option typically requires a compatible 58.8V full-charge lithium-ion charger. Your controller must explicitly support a 52V battery system.

Important: These charging voltages apply to conventional lithium-ion battery packs with the corresponding series-cell configurations. Always confirm the specifications of the exact battery you purchase.

Which Battery Capacity Should You Choose?

Battery capacity, measured in amp-hours (Ah), affects how much energy a battery can store. At the same nominal voltage, a higher Ah rating generally provides more stored energy.

Actual riding range depends on rider weight, terrain, speed, motor power, tire pressure, temperature, and riding conditions. Do not rely on battery capacity alone to predict mileage.

Compatibility Guide

Before purchasing, verify these details:

1. Voltage: Match the battery voltage to the controller's approved operating range.

2. Capacity: Confirm the exact Ah option available for your chosen voltage.

3. Continuous current: Check that the battery's BMS continuous discharge rating meets the controller's requirements.

4. Peak current: Confirm the duration of any advertised peak-current rating.

5. Mounting dimensions: Compare the listed dimensions with the available space on your bike frame.

6. Connector and polarity: Ensure the battery connector, wiring, and polarity match your system.

7. Charger: Use only a charger approved for the exact battery voltage and chemistry.

The listing mentions Bafang, Voilamart, CSC, and motors rated at 500W, 750W, 1000W, and 1500W. Compatibility is not guaranteed for every motor or conversion kit. A motor's wattage alone does not establish battery compatibility.

What's Included?

The supplier advertises a charger with the battery. Confirm the selected variant's package contents before ordering, including the charger output voltage, connector, mounting cradle, keys, and any required wiring.
