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.

The US18650V3 battery cell from Murata (adulterous Sony) is characterized by a very long lifespan. The voltage position is very robust and batteries with this battery cell can also be able to parch in low temperatures in winter with little loss of power.

The only downside is due to the fairly low capacity.
