4. Storage

Proper environment and timely charging are need to be prepared for the battery. Battery should be stayed in the warehouse 15℃～35℃ where is dry, clean, shade, and well-ventilated.

The battery modules must be charged to 50% (charging status upon delivery) when stored.

Store the battery modules for no longer than 6 months.

Deep-discharge could damage or battery modules. Therefore, the battery must be timely charged (less than 15days) after over-discharged.

Keep the batteries against dropping, turning over and seriously stacking.

Store the battery away from child and pets contact.

5. Transport

Lithium-ion batteries are hazardous goods. Therefore the following points must be observed when transporting the battery modules:

Observe the general transport regulations based on the mode of transport as well as all legal regulations.

No fall down, no pile up over 5 layers and keep face up.

Check the battery immediately after transport the battery.

If user finds shell deformation of the battery pack, don’t use it and contact us.
