Important general information

The 36V batteries in Hailong I case, which we assemble, are so-called “Frame Batteries”, which can be fixed to the bike’s frame. The batteries are assembled with plastic cell-holders. Charging is enabled using a DC round plug (5.5 mm / 2.1 mm) and discharging is done with a discharge cable with an XT90 plug.

The Hailong I is the most compact case of its kind with space for 40 18650 Li-ion cells, and suitable especially for users, which are looking to save space on the bikes. The battery is placed in a case which can be easily mounted on the frame of the bike.

The battery is also equipped with a USB socket, which allows you to use it as a power bank to charge your mobile devices (smartphone, tablet etc.) on the road (up to 12W output power).

The BMS (Battery Management System) can somewhat withstand a constant current (22A). Hence this battery is suitable also for motors with up tp 750W.
