Advantages of 3.7v li-ion battery

Durability:

Lead-acid batteries are generally deep-charged and deep-discharged within 400 times, with memory and a life span of about two years. If you are using a maintenance-free lead-acid battery, it should be noted that the battery has less water loss, and it is generally not necessary to add distilled water during use. Lithium batteries are durable, consume slowly, charge and discharge more than 500 times, and have no memory. The general life span is 4-5 years.

Volume and quality:

Generally, the weight of the lead-acid battery pack is 16-30 kg, and the volume is relatively large; the lithium battery is generally 2-6 kg, and the volume is relatively small, so the riding is light and easy to carry. As far as quality is concerned, it is difficult to define whether the two are good or not, and consumers can purchase batteries produced by regular manufacturers according to their own needs.

In terms of price and warranty period:

At present, the mainstream battery in the market is 48 volts. If it is replaced, the lead-acid battery is about 700 yuan, and the warranty period is 1 year; the lithium battery is relatively expensive, requiring about 1,200 yuan, but the warranty period can be 3 years.
