1. Durability:
Lead-acid battery is generally charged and discharged less than 400 times, with memory and a life of about two years.If a maintenance-free lead-acid battery is used, it should be noted that its battery has little water loss, and generally there is no need to add distilled water in use.
Lithium battery has strong durability, slow consumption, charging and discharging more than 500 times, and no memory, and the general life is 4-5 years.In terms of durability, the battery has good shock resistance and is safely fixed in a fully charged state. The battery vibrates for 1 hour with an amplitude of 4mm and a frequency of 16.7Hz. There is no leakage, no battery expansion or rupture, and the open-circuit voltage is normal.Good overcharge resistance, 25 ° C, fully charged state battery 0.1CA charging for 48 hours, no leakage, no battery expansion and rupture, normal open circuit voltage, capacity maintenance rate of more than 95%;Good resistance to large current, fully charged battery 2CA discharge for 5 minutes or 10CA discharge for 5 seconds, no conductive part of the fuse, no appearance deformation.
2. Volume and mass:
General lead-acid battery weight is 16-30 kg, large volume;Lithium batteries are generally 2.5-3kg, relatively small in size, so cycling is light and easy to handle.In terms of quality, which is better or worse is difficult to define, according to their own needs, consumers can buy regular manufacturers of good quality brand batteries.
3. Price and warranty period:
At present, the mainstream battery on the market is 48 volts. If replaced, the lead-acid battery is about 450 yuan, and the warranty period is 1 year.Lithium-ion batteries are relatively expensive, costing around 1,000 yuan, but are guaranteed for two years.
4. Mileage:
On a full charge, both lead-acid and lithium-ion batteries can travel 30-40 kilometres on the same 48V battery.The speed depends largely on the size of the motor used.
5. Battery capacity:
The capacity of lead-acid battery is about 20 amps.Lithium batteries have a capacity of 8-10 amps.
6. Environmental Protection:
After the state promulgated the "Conditions of Access to lead battery Industry" in 2012, the lead acid industry has been reorganized and integrated. Most manufacturers have adopted the internalized green production without cadmium and arsenic, which is more environmentally friendly and energy-saving.Lithium batteries are relatively greener in terms of production and recycling.
