Storage & Transportation
* Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
* Battery should be stayed in the ware house -20℃～35℃ where it’s dry, clean, shade, and well-ventilated.
* The battery should be stored in 50% SOC during transportation.
* The battery need to be charged every 6 months if out of use.
* Keep the battery against dropping, turning over and serious stacking during loading.

Warning & Tips
Please read and follow the specification and caution remarks on battery surface before use the battery. Improper use may cause heat, fire, rupture, damage or capacity deterioration of the battery. Describes is not responsible for any accidents caused by the usage without following our specification.
Warning！
* The battery must be far away from heat source, high voltage, and avoid to be exposed in sunshine for long time.
* Never throw the battery into water.
* Never connect the positive and negative of battery with metal.
* Never sheep or store battery together with metal.
* Never reverse two electrodes when use the battery.
* Never disassemble the battery without manufacturer's permission and guidance.
* Never knock, throw or trample the battery.
Tips！
* Keep the battery against high temperature. Otherwise it will cause battery heat, get into fire or lose some function and reduce the life.
* When battery run out of power, please charge your battery timely (≤15day).
* Please use the matched or suggested charger for this battery.
* If battery emit peculiar smell, heating, distortion or appear any abnormity during working or storage, please stop using and take it out from device.
* If the battery leaks and get into the eyes or skin, do not wipe, instead, rinse it with clean water and see doctor immediately.
* Please far away from children or pets.
* Do not put disuse battery into a fire or water.
* It is strictly prohibited any series between the battery packs.
