Features:
Long Service Life
Many Charge and Discharge Cycles: The number of charge and discharge cycles can reach 1,000 - 3,000 times. Calculated with 70% capacity retention, the 100% charge and discharge cycle times of the battery pack can exceed 200 times, and the service life can reach 5 - 8 years, which is about 2 to 3 times that of lead - acid batteries.
Low Self - Discharge Rate: The self - discharge rate is less than 5% per month. Even if not used for a long time, it can still maintain a relatively high power, which is convenient for users to use at any time.
Good Safety Performance
Perfect Protection Function: The battery management system (BMS) can monitor each cell with high precision and perform low - power intelligent management. It has perfect protection functions such as overcharge, overdischarge, overtemperature, overcurrent and short - circuit protection, as well as reliable equalizing charge function, which can effectively extend the service life of the battery and ensure the safety of use.
Stable Chemical Properties: Some lithium - ion batteries use phosphate iron lithium as the positive electrode material. Even if the battery is internally or externally damaged, it will not burn or explode, and has good safety.
Environmentally Friendly
No Toxic Substances: Li - ion batteries do not contain toxic substances such as lead and cadmium. They are called "green batteries" and are more environmentally friendly, which is in line with the concept of sustainable development.
Low Pollution: During the manufacturing and using process, it produces less waste water, waste gas and other pollutants, which has little impact on the environment and helps to promote the green development of the e - bike industry
