Battery charge notice
It is important to consider temperature when the battery pack is charging.
Charging is most efficient at normal room temperature or in a slightly cooler
environment. It is essential that batteries are charged within the stated range of
0°C to 40°C. Charging batteries outside of the specified range could damage
the batteries and shorten their life cycle.
CAUTION! Do not charge batteries at a temperature lower than 0°C. This will
and make the batteries unstable and dangerous. Please use a
battery temperature detecting device for a charger to ensure a
safe charging temperature range.
CAUTION! To ensure the unit working properly, please keep all connectors
away from the contaminants staying inside of them such as dust,
grease, mud, and water. The negligence may cause the unit with
no communication, short circuited, overheated and so on.
CAUTION! If the connector is damaged, please ensure the connector is being
fully repaired before use the unit to avoid causing short circuited.
