Solar street light is a good or gel battery with lithium batteries?

- -

recently a customer asked me again, solar street lights is to use lithium battery or gel battery? In fact, for this problem, there is no absolute certainty. Now let's look at their respective advantages and disadvantages.

1, the advantages of lithium battery

the average voltage of the lithium battery is better, the depth of discharge is higher, its energy density is high also, in other words the same size of lithium batteries and gel batteries, lithium batteries more energy. Charging speed faster, and lithium battery solar street lamp installation is more simple and convenient, do not need to bury the battery, greener.

2, the shortcomings of the lithium battery

security stability than gel battery, cost more expensive relative to the colloid battery, cold weather in the north prone to damage, greatly influenced by temperature. So the north is not suitable for installation of lithium battery solar street lamps.

3, the advantages of gel battery

gel battery price is cheaper, more acceptable, and the gel battery is old technology, more stability, more cycles, so relative to the lithium battery service life is longer.

4, colloid battery defect

low energy density, low discharge depth, charging slow, high weight, it is not convenient to installation and maintenance after

the lithium battery has many advantages, but the market is lithium battery solar street lamp is not much, could people for its technology not trust, but lithium battery technology have been developed for many years, although there are flaws, but the south is worth using.

all in all, the emergence of lithium battery and applied to the street lamp is the progress of the solar street lamp industry, with the continuous development of technology, I believe the future a lot of problems will be solved, then lithium battery solar street lamps will be all over the country.
