1. Durability: The battery is generally charged and discharged for 300 times, with memory, and its service life is about two years. And there is liquid in the battery. After a period of time, if the battery is found to be hot or the charging time is shorter, it is necessary to replenish the liquid. Lithium ion battery has strong durability, slow consumption, more than 500 times of charging and discharging, no memory, and a general life of 4-5 years.

2. Volume and quality: Compared with batteries with the same capacity on the market, lithium-ion batteries have a volume of 2/3 of the battery's volume and a weight of about 1/3 of the battery's weight. The capacity of lithium-ion batteries with the same volume is higher than that of batteries. The reduction of weight increases the endurance of electric vehicles by about 10%.

3. Price and warranty period: At present, the mainstream battery in the market is 48V. If it is replaced, the battery will cost about 450 yuan, and the warranty period is one year. Lithium ion batteries are relatively expensive, about 1000 yuan, but the warranty period is two years.

4. Charge and discharge resistance: The lithium-ion battery can keep charging for 48 hours under normal temperature without battery expansion, leakage, rupture and other accidents, and its capacity is kept above 95%. In addition, it can conduct rapid charging and discharging under the special charger.

5. Environmental protection: Lead acid battery is polluted in the production process. If it is not recycled properly, it may also cause pollution; Lithium ion batteries are relatively green.
