Durability:

Generally, lead-acid batteries can be deeply charged and discharged for less than 400 times, with memory and a service life of about two years. If the maintenance free lead-acid battery is used, it should be noted that the water loss of the battery is small, and distilled water is generally not required in use. Lithium battery has strong durability, slow consumption, more than 500 times of charging and discharging, no memory, and a general life of 4-5 years.

According to experts, as far as durability is concerned, lithium battery has good vibration resistance. The battery in fully charged state is securely fixed. It vibrates for 1 hour with an amplitude of 4mm and a frequency of 16.7Hz. There is no leakage, no battery expansion and rupture, and the open circuit voltage is normal; Good overcharge resistance, 25 ℃, fully charged battery 0.1CA charge for 48 hours, no leakage, no battery expansion and rupture, normal open circuit voltage, and capacity maintenance rate above 95%; Good resistance to large current. The battery in fully charged state is discharged for 5 minutes by 2CA or 5 seconds by 10CA. No conductive part is fused and no appearance deformation is found.

Volume and quality:

Generally, the weight of lead-acid battery pack is 16-30kg, and the volume is large; The lithium battery is generally 2-6kg, which is relatively small, so it is easy to ride and carry. As far as quality is concerned, it is difficult to define which is better or worse. Consumers can buy batteries produced by regular manufacturers according to their own needs.

Price and warranty period:

At present, the mainstream battery in the market is 48V. If it is replaced, the lead acid battery will cost about 700 yuan and the warranty period is one year; Lithium batteries are relatively expensive, costing about 1200 yuan, but the warranty period can be 3 years.

Driving kilometers:

With the same 48V battery, both lead-acid battery and lithium battery electric vehicles can travel 30-40km when fully charged. The speed mainly depends on the size of the motor used.
