Important General Information

This 36V (37V) Li-ion battery in Hailong-I case, ehich we assemble is a frame battery (fixed on the frame of the bike). The batteries are manufactured in plastic cell brackets. Charging is done via a DC round plug (5.5 mm/2.1 mm), discharging is done via a discharge cable with XT90 connectors (male), which comes out of the case of the battery.

The Hailong I is the smallest case of its kind with space for 40 18650 Li-ion cells and is suitable for users which are more looking to save space and weight. The battery comes with a mount that can be mounted on the frame of the bike.

Our BMS (Battery Management System) can withstand a lot of continuous load (22A). This battery is also suitable for engines with up to 750 watts.
