Products Description
The Ebike Lithium Battery serves as the vehicle's energy unit, providing DC power output to the motor and control system. This battery is suitable for urban commuter e-bikes, folding bikes, lightweight bikes, and all-terrain fat-tire e-bikes, and its structural and electrical parameters can be matched to the vehicle's power requirements and frame space.
Advantages
Grade A Power Cells
Utilizes Grade A power cells sourced from large-scale cell manufacturers such as CATL, BYD, and EVE Energy, ensuring consistent battery pack configuration.
Continuous Output
Nominal 36V system, operating voltage range 27.5V–42V, maximum continuous discharge current 25A, covering motor power requirements from 250W to 750W.
IP67 Protection
The sealed casing meets IP67 standards, preventing dust ingress and withstanding rain or short-term immersion.
Hardware-Level BMS Protection
The BMS is integrated within the battery, providing overcharge, over-discharge, overcurrent, short-circuit, and temperature protection through hardware circuitry. Protection actions are executed by detection circuits and MOS switches, eliminating the need for an external control system.

FAQ
Q: How to choose between LiFePO4 and ternary lithium batteries?
A: LiFePO4 has a longer cycle life and higher thermal stability; ternary lithium batteries have higher energy density and a lighter overall pack weight. Choose based on your range requirements and vehicle weight goals.
Q: Can a 25A maximum discharge support a 750W motor?
A: In a 36V system, a 750W motor operates at approximately 20A. A continuous 25A discharge can cover this power range.
Q: Can the battery be used in low-temperature environments?
A: The charging temperature range is -20℃ to 55℃, and the discharging temperature range is 0℃ to 45℃. Discharge capacity will decrease at low temperatures due to material properties.
Q: Can IP67 be used in rainy weather?
A: IP67 protects against rain and short-term immersion, but prolonged immersion or high-pressure water washing is not recommended.
Q: Can the battery be compatible with different controllers?
A: As long as the controller voltage platform is consistent and the current requirement is within the battery's discharge range, it can be matched.
Q: Can the BMS parameters be changed?
A: Current limits and communication protocols can be adjusted according to the vehicle's control strategy.
