Kirbebike HS-II E-bike Lithium Batteries with 5A Fast Charger | 52V, 60V, 72V Options

This battery is available in multiple voltage and capacity options, making it suitable for a wide range of e-bike setups. Before ordering, we recommend checking your motor power, controller voltage, connector type, and available frame space to make sure the battery is compatible with your bike.If you're not sure which version is right for your setup, feel free to send us your motor and controller specs, and we’ll help you choose the best option.

The battery voltage must match your e-bike system and should not be mixed with a different voltage setup.In general:

• 36V / 48V / 52V are better suited for daily commuting and standard upgrades
• 60V / 72V are better suited for high-power systems, offering stronger speed and torque performance

For example, if your motor and controller are built for a 48V system, you should choose the 48V battery version. Choosing the wrong voltage may result in poor performance, system instability, or the battery not working properly.

This battery is equipped with a 60A BMS, which helps provide more stable power output and improves reliability during both everyday riding and higher-load use.It is also built with LG / Samsung premium cells, offering better consistency, stability, and long-term performance.
Overall, this battery is designed not just for capacity, but for dependable power delivery, improved safety, and long-term reliability.

This battery is rated IP65, which means it can handle light rain, splashes, and normal outdoor riding conditions.However, IP65 does not mean the battery should be submerged in water or exposed to high-pressure washing. To protect the battery and extend its lifespan, we recommend avoiding heavy rain, deep water, and direct pressure washing.

Actual range depends on several factors, including battery voltage and capacity, rider weight, road conditions, riding speed, temperature, and motor power.Depending on the battery version and the motor power it is paired with, the estimated riding range is typically around 30–70 km, with some higher-capacity versions reaching even more under the right conditions.For charging, this battery supports 5A fast charging, and most versions can be fully charged in about 4–5 hours. This helps reduce waiting time and makes it a practical choice for commuting and frequent daily use.
