Long service life of lithium batteries

The annual loss of lead-acid batteries is so fierce that they often need to be replaced once a year or two. The service life of lithium-ion batteries is 3-5 years, which can generally be guaranteed for three years. The cycle life of lead-acid batteries is 300 times. For lithium iron phosphate batteries, the cycle life of 3C is more than 800 cycles.

 Lithium batteries have higher safety and no memory effect.

Lead-acid batteries are easy to enter water, lithium batteries are not easy to enter water. Moreover, lead-acid batteries have memory, that is, when they are not fully discharged, the charging will have memory effect, which will affect the service life of the batteries. Lithium batteries have no memory and can be charged at any time. This is safer and more reassuring to use. Lithium iron phosphate has gone through rigorous safety tests and will not explode even in severe collisions.

High energy density of lithium batteries

Lithium batteries have a high storage energy density, reaching 460-600Wh/kg, about 6-7 times that of lead-acid batteries. This will better store energy for solar street lamps.
