Is it better to lithium battery or lead -acid battery?solar powered generator for camping

　　According to the current trend, the function of lithium batteries is better than lead -acid batteries. The number of long cyclic life: The charging and discharge rate of lithium -ion battery is 1C. Its cycle life is greater than or equal to 500 times.

　　2. Good low-temperature discharge function: Lithium ion battery can operate normally at -25 ° C, the capacity can reach 70 % of the standard, and the lead-acid battery can reach 50 % at -10 ° C, but- Do not work normally at 25 ° C.

　　3. Strong endurance. The weight of the lithium -ion battery is only 30 % of the lead -acid battery, so at the same voltage and capacity, the durability of the lithium -ion battery is strong.

　　4. High ratio: Because the volume of lithium ion batteries is only 30 % of the volume of lead -acid batteries, in the same space, the energy of lithium ion batteries is greater than the lead -acid battery.

　　5. The operating temperature range is wide: lithium-ion batteries can work within the range of -25C to 55C, while lead-acid batteries can only work within the range of 10c to 40C.

　　6. Short charging time: Lithium-ion batteries can charging large currents. The charging time is only 4-5 hours. The lithium battery can be charged continuously for 48 hours. There will be no accidents such as battery expansion and leakage rupture. The capacity remains above 95 %. And under the dedicated charger, fast charging and discharge can be performed. The lead-acid battery takes 8-10 hours.

　　7. High environmental function: Compared with lead -acid batteries, lithium -ion batteries are very environmentally friendly products. Lead -acid battery contains a large number of heavy metal lead that is harmful to the human body and the environment.

　　8. Large -current discharge: Lithium -ion battery discharge a large current at 1C, and the capacity is only 60 % of the additional capacity.

　　9. Large -current discharge does not affect the number of cycle life: Lithium -ion battery 1.5C multiplier large current discharge does not affect the number of cycle life. However, lead -acid batteries discharge at a high current of 1.5C. Its cycle life is only 30-40 % of the nominal loop life.
