8. 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 warehouse 15℃~35℃ where it’s dry, clean, shade, and well-ventilated.

* The battery should be stored in 50% SOC during transportation. (The suggest method: Charge the battery fully29.2V, and discharge the battery until reaches the discharge cutoff voltage20.0V, then charge the battery up to 50% SOC26.4Vand storage in proper circumstance according specification.)

* The battery need to be charged every 6 months if out of use

9. Warning & Tips

Before using the battery, please read and follow the specifications and precautions on the surface of the battery. Improper use may cause heat, fire, rupture, damage, or capacity deterioration of the battery. Shenzhen Guanyu New Energy Technology Co., Ltd. is not responsible for any accidents caused by use, which does not meet our specifications.

² The battery must be far away from heat source, high voltage, and avoid to be exposed in sunshine for long time.

² Never throw the battery into water.

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 manufacturer, 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 emit peculiar smell, heating, distortion or appear any abnormity during working or storage, please stop using and take it out from 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.

² It is strictly prohibited any series between the battery packs. Any requirements on serials connection, please contact GUANYU for details.

 

10. Battery operation instruction

10.1 Charge and discharge

10.1.1 Charging current:Do not surpass the largest charging current that specification stipulated.

10.1.2 Charging voltage:Do not surpass the highest limited voltage that specification stipulated.

10.1.3 Charging temperature:within temperature scope that specification stipulated.

10.1.4 Charge with constant current, then with the constant voltage, no reverse charge, which is dangerous

10.1.5 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 long time floating please use the recommended floating model specification.Battery when not in use for a long time, because of its own self-discharge characteristics can also cause discharge, to prevent the occurrence of a discharge, battery should maintain a certain capacity, maintain the voltage at 50% state of SOC.

 

11. 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 full charged, even battery is charged correctly, and this may indicate it is time to

change the battery.
