Choosing a lithium battery or a lead-acid battery depends on your specific needs and use environment. 12
Price and cost: The price of lead-acid batteries is usually lower than lithium batteries, which is more suitable for users with limited budgets. For example, a 48V20AH lead-acid battery costs about 550 yuan, while a lithium battery of the same specification costs about 1,300 yuan.
Service life: The average service life of lead-acid batteries is about two years, while the service life of lithium batteries is long, up to 3 to 4 years.
Safety performance: The safety of lead-acid batteries is high, and fewer safety accidents occur. In contrast, lithium batteries have poor safety performance and are prone to spontaneous combustion or explosion, especially when improperly used or damaged.
Applicable population: If users do not have particularly high requirements for the service life and battery life of electric vehicles, only daily traffic use, lead-acid batteries are enough to meet the needs. For users who need to use electric vehicles frequently, such as take-out brothers and express brothers, lithium batteries can better improve work efficiency.
Lightness: Lithium batteries are light and small, while lead-acid batteries are large and bulky. Compared with batteries of the same size, the weight of lithium batteries is only one-third of that of lead-acid batteries.
Charging performance: Lithium batteries have higher charging and discharging efficiency, no memory effect, and can be charged at any time. The charging and discharging efficiency of lead-acid batteries is relatively low, there is a memory effect, and it needs to be fully discharged regularly to maintain the battery performance.
Technology maturity: Lead-acid battery technology appears more than 100 years earlier than lithium batteries, and the technology is mature and stable. Lithium batteries are still relatively new products, and there are safety flaws.
To sum up, if you pay attention to cost, have low requirements for battery performance and have high requirements for safety, lead-acid batteries are a better choice. If you are looking for high performance, lightweight, long life and fast charging, while not mind high initial costs and relatively low safety, then lithium batteries may be more for you. The final choice should be based on your actual needs, economic situation and use of the environment to decide.
