Do not short-circuit the positive and negative poles of the battery, do not disassemble the 

battery by yourself, and do not leave the battery in a damp place to avoid danger.

Discarded batteries should be handled safely and properly, do not put into fire or water.

The battery pack should be stored at ambient temperature and should be charged to a 

capacity of 40%~60%. To prevent overdischarge of the battery, please charge it every 3 months.

The battery pack should be used under specified conditions, and battery performance over 

one year of storage is not guaranteed.

The battery must meet relevant regulations during transportation, such as packaging, 

documentation, and labeling requirements.

Cannot be used in mixed batches, only in series with the same batch.  

The difference between the total module voltages should ≤ 100mV when the battery modules are in series.  

The connecting conductors used in the series module should be as thick and conductive as possible, the 

contact surface at the series should be large, contact looseness and other phenomena should not occur, 

and the series resistance between the modules should be reduced as much as possible.  

Maximum 4 battery modules in series.

If the product is used incorrectly, the circuit is connected incorrectly, the input power or the 

load function parameters do not match the performance parameters marked in the product 

specification, etc., these phenomena are improper use. The company does not assume any 

responsibility for damage to the product, load and surrounding connections due to improper use.
