Choose Your Battery Capacity

36V Battery Options

• 36V 10Ah — 360Wh

• 36V 15Ah — 540Wh

• 36V 20Ah — 720Wh, calculated from voltage and capacity

48V Battery Options

• 48V 10Ah — 480Wh

• 48V 15Ah — 720Wh, calculated from voltage and capacity

• 48V 20Ah — 960Wh

Watt-hours (Wh) indicate stored energy. A higher-capacity battery generally stores more energy, but actual riding range depends on motor power, rider weight, terrain, speed, temperature, and riding conditions.

Built-In Battery Management

The supplier advertises BMS protection against:

• Overcharging

• Over-discharging

• Overcurrent

• Overheating

• Short circuits

The supplier lists a 30A BMS for 10Ah versions and a 40A BMS for 15Ah and 20Ah versions. Confirm the specifications for your selected battery before ordering.

Check Compatibility Before Ordering

Before purchasing, confirm all of the following:

1. Your bike uses the correct nominal battery voltage: 36V or 48V.

2. Your battery rail and mounting dimensions match the Hailong case.

3. Your battery holder has the correct connector and pin arrangement.

4. Your controller supports the selected battery voltage and required current.

5. Your charger matches the battery chemistry and specified charging voltage.

A 36V battery and a 48V battery are not interchangeable unless the bike's electrical system is specifically designed to support both.

Important Technical Note

The supplied specifications contain conflicting battery chemistry information: the product is described as both lithium-ion using 18650 cells and lithium iron phosphate (LiFePO4). These chemistries can require different cell configurations and charging voltages. Confirm the actual chemistry, charger requirements, connector wiring, and battery configuration with the supplier before listing or using the product.

Order the correct voltage and capacity for your e-bike. Check your existing battery label and mounting system before selecting a replacement.
