Battery maintenance

  • If you know you won’t be using the battery for more than a few days, keep it charged at about 80% capacity. At 80%, the battery will degrade less than at higher charge levels.
  • The battery would possibly be in an over-discharged state if it is not used for a long time. In order to prevent over-discharging, the battery shall be charged periodically (Recommended 3 months one cycle). Over-discharging may cause loss of cell performance, characteristics, or battery functions.
  • Don’t immerse the battery in water, and keep the battery in a cool dry surrounding if it stands by.
  • Don’t use or leave the battery at high temperatures as a fire or heater. Otherwise, it can overheat or fire, or its performance will degenerate and its service life will be decreased.


  • The battery can be charged while it is attached to or detached from the e-bike. (You can remove the battery by inserting the key into the lock on the side face of the battery slide. To lock the battery, insert the key into the lock on the side face of the battery slide.) 
  • Use the original charger to charge the battery.
  • When charging the battery, first connect the charger and the battery end, and then plug the charger into power.
  • The light on the charger will be red when the battery is charging and will turn green when charging has finished. 
  • Avoid leaving the charger plugged in when the battery is fully charged. 
  • Charging the battery should take approximately 4-6 hours if the battery is mostly empty.


  • Do NOT submerge the battery in a liquid of any kind.
  • Do NOT use any metal to touch the charging port, that will cause a short-circuit.
  • Turn off the battery when not in use and before removing it from the e-bike.
  • Only grab the charger by the plug and not the cable when plugging and unplugging from the wall.
  • Lithium-Ion batteries can be dangerous. Take care when using and charging your battery. Failure to follow the above guidelines could result in damage to property and/or serious injury. Contact us immediately if you have any questions regarding battery safety.
