This depends on how you use it and which car and battery you use. An electric bicycle powered by lithium iron phosphate batteries currently has two main voltages: 24V10AH and 36V10AH. There are dozens of companies that make lithium iron phosphate cells. It is estimated that the electric bicycle combined with cylindrical lithium iron phosphate cells will not exceed Ten. The battery factory packs the battery pack and the casing and provides it to the bicycle factory for assembly and delivery to the end customer. Generally, the cycle life of a single battery cell exceeds 2,000 times. Due to consistency issues, it is estimated that the cycle life of a good battery cell will be around 1,000-1,500 times. The length of use depends on the protection function of the protective board and the user's usage. power status. If it is shallowly charged and discharged, the cycle life will be very long.
