Product information "HaiLong I Frame Battery Li-Ion 36V 11.4Ah with 29E"

ENERpower HaiLong Frame Battery Li-Ion 36V 11.4Ah for Pedelecs & eBikes DIY Conversion Kit, powered by 29E battery cells from Samsung.

  • For motors from 250 Watts and up to 750 Watts

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

So you can choose not only the connector itself, but also the right charger. The difference between the chargers is due to the different output currents (charging speed).

* For technical reasons we cannot ship Hailong batteries to Italy. We apologize for the inconvenience.
