Upgrade your electric bicycle with this Hailong rechargeable lithium pack that delivers up to 52V20Ah (1040Wh) of reliable range for daily commutes or weekend expeditions.
You will match your drivetrain easily thanks to broad compatibility across standard mid-drive and hub motor systems running between 250W and 1500W.
You can monitor energy levels instantly through an integrated LED display while relying on a multi-stage BMS that safeguards against short circuits, overheating, and deep discharge.
You can switch between downtube and rear rack mounting profiles depending on your frame geometry, securing the unit with dedicated locking keys against theft.
You will sustain capacity through extensive charge cycles in varying conditions, as the internal cells handle discharge down to -15°C and operate safely when recharged between 0°C and 45°C.
