The composition of an electric motorcycle battery

Battery Cell

The core of the battery is crucial, affecting overall lifespan and stability. We have long-term procurement of various cells, including Samsung, LG, 18650, 21700, soft shell, and hard shell, to ensure the best choices.”


BMS (Battery Management System) is an essential component used to manage the stable operation of battery packs. In China, many companies use third-party protection boards, but we have our own developed BMS protection board, allowing for a more comprehensive control of battery performance.

Fire-proof shell

For some past orders, we required the batteries to be dustproof and waterproof. We have rich experience and the materials needed to meet IPX67-level requirements.
