WARNING

If the battery can not be fully charged after 12 hours, please stop charging and contact 
your dealer.
To maximize the battery life, please keep the battery percentage within 20% to 80%.
The battery will lose more capacity in lower temperature conditions. To be more        
specific, the usable capacity at -10°C is 70%, 85% at 0°C, and 100% at 25°C.
The best battery capacity performance for storage is 50%. Storing battery with less than 
10% or more than 90% over a long period of time will cause irreversible capacity loss to 
the battery.

The battery needs to take out from the scooter for storage longer than one week.

 In this 

condition, please keep the battery at the temperature of 0°C to 20°C with capacity of 
30%-70%. It's advised to have at least one cycle of charge and discharge every 2 months 
to minimize battery capacity loss during storage.

If the battery failure is due to misuse or lack of proper maintenance as instructed, its 
warranty will be invalidated. 

Falling may cause uncontrollable internal damage to the battery and may cause      
leakage, overheat, smoking, fire or explosion.
