1. Safety Precautions
This section describes the safety information that must be observed when working with battery
packs. To prevent any damages, or personal injury, and to ensure the performance of the battery
packs, please read this section carefully and observe the safety precautions at all times.
1.1 Precautions
It is very important and necessary to read the user manual carefully before installing or using
the product. Failure to do so or to follow any of the instructions or warnings in this document
can result in electrical shock, serious injury or death, and could damage the battery, or
potentially rendering it inoperable.
If the battery pack is stored for long time, it is required to charge them every six months, and
the SOC should be no less than 90%.
Please recharged the battery pack within 12 hours, after fully discharged.
All the battery pack terminals must be disconnected before any maintenance.
Do not use cleaning solvents to clean battery pack.
Do not expose battery pack to flammable or harsh chemicals, or corrosive gases or liquids.
Do not paint any part of battery pack, include any internal or external components.
Do not expose the battery pack to direct sunlight for extended periods of time.
