In recent years, with the large-scale use of lithium batteries for two-wheeled electric vehicles, some lithium battery accidents have occurred from time to time, so many people can't help but wonder whether it is really feasible to replace lead-acid batteries with lithium batteries, and whether battery car batteries should choose lithium batteries or As for lead-acid batteries, today, together with Topbond lithium batteries, we will discuss the differences between lithium batteries and lead-acid batteries from four aspects: service life, cost performance and endurance:

Mass volume

Lead-acid batteries are relatively large in size and heavier. Compared with lithium batteries, which weigh only two or three kilograms, lead-acid batteries with the same capacity generally require more than ten or even twenty kilograms. Although many lead-acid batteries have also begun to use light weight Quantitative design, but the flexibility and detachable installation method of lithium-ion batteries are better than lead-acid batteries;

Service life

At present, the service life of lead-acid batteries is generally about two years, and the cycle charge and discharge is generally within 300 times, while the cycle charge and discharge of lithium batteries exceeds 500 times, and the general service life reaches and exceeds 3 years. Many lithium battery manufacturers still Provide three-year product warranty time;

Cost-effective

At present, the price of mainstream lead-acid batteries is basically around 450 yuan, and lithium batteries will be relatively more expensive. With the reduction of lithium battery raw materials, there will be brands that will make the price of lithium batteries equal to that of lead-acid batteries;

Cruising range

This is a problem that many battery car users are very concerned about. If the same 48V battery is used, the battery life of a lithium battery and a lead-acid battery is actually similar when fully charged. It mainly depends on the speed and the power of the motor, etc. several factors;

lithium battery

To sum up, when the user is more sensitive to price, they can choose to use lead-acid batteries. If they care more about the operability, service life and performance of the battery, they can choose lithium batteries. Safety issues are the industry's top priority：Shenzhen Topband Battery Co., Ltd.，established in 2006, is a wholly-owned subsidiary of Shenzhen Topband Co., Ltd. (002139.SZ).
