Recommended storage environment:
Long time storage:
If the battery need be stored for a long time, the voltage should be 52.8V (50%SOC), and stored in the condition as storage proposal. It need at least one charge & discharge cycle every six months.
² Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
² Battery should stay in the warehouse 15℃～35℃ where it’s dry, clean, shade, and well-ventilated.
² The battery should be stored in 50% SOC during transportation.
² The battery needs to be charged every 6 months if out of use
² Keep the battery against dropping, turning over and serious stacking during loading.
² Ensure the single 48V 100Ah battery module in the independent package and keep it face up.
6. Warning & Tips
² 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. SHENZHEN TOPBAND BATTERY CO.,LTD. Describes is not responsible for any accidents caused by the usage without following our specification.
² The battery must be far away from heat source, high voltage, and avoid to be exposed in sunshine for a long time.
² Do not put the battery in a charger or equipment with wrong terminals connected.
² Never connect the positive and negative of battery with metal.
² Avoid excessive physical shock or vibration. don't hit, fall, stamp on the battery
² Without the permission of the manufacturer and guidance, forbidden to remove or to assemble the battery
² Do not use the battery mixed with other different manufacturers, type, or model batteries.
² Keep the battery against high temperature. Otherwise, it will cause battery heat, get into fire or lose some function and reduce the life.
² When battery run out of power, please charge your battery timely (≤15day).
² Please use the matched or suggested charger for this battery.
² If battery emits a peculiar smell, heating, distortion or appears any abnormity during working or storage, please stop using and take it out from the device.
² If the battery leaks and get into the eyes or skin, do not wipe, instead, rinse it with clean water and see doctor immediately.
² Please far away from children or pets.
² Do not put disuse battery into a fire or water.
7. Battery operation instruction
7.1 Do not surpass the largest charging current that the specification stipulated.
7.2 Do not surpass the highest limited voltage that the specification stipulated.
7.3 Charging temperature:within temperature scope that specification stipulated.
7.4 Charge with constant current, then with the constant voltage, no reverse charge, which is dangerous
7.5 Special note:
Short time doesn't affect the use of the battery overcharge too, but for a long period of time over discharge or over charge can affect the function of the battery failure, or the battery can't use permanent, appear serious safety hazards, need a long time floating please use the recommended floating model specification.
8. Other Chemical Reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges, the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the discharge time is much shorter than the normal after fully charged, even battery is charged correctly, and this may indicate it is time to change the battery.
