How to choose the battery of solar street light?

How to choose solar light batteries? Today, the first choice for solar street lights in the world is still split street lights. Split street lights use lead-acid batteries, which are either attached to the light pole or buried in the ground next to the light pole. In the burial box. The other is a lithium battery, which is placed on the other side of the panel assembly. 1. Environmental protection: Lithium batteries have no pollution (not absolute), and lead-acid batteries have heavy metal lead pollution. 2. Safety: Dynamic lithium batteries (lithium manganate and lithium iron phosphate) have differences in safety. Lead-acid battery technology is quite mature, and its safety is higher than that of lithium batteries. 3. Specific energy: The mass ratio and volume ratio of lithium batteries are about 40% higher than that of lead-acid batteries. 4. Price: Lithium batteries with the same capacity are more than twice as expensive as lead-acid batteries. 5. Service life: At present, the general lithium iron phosphate is charged 1500 times, and there is no recall effect. Recharge 1500 times, obtain 85% storage capacity, lead-acid battery charge about 500 times, the recall effect is remarkable 6. Self-discharge rate: monthly self-discharge rate of lithium battery u003c3%, lead-acid battery 15-30%, the difference is significant 7. Discharge characteristics: In simple terms, for batteries of the same capacity, in the case of high current discharge, lithium batteries emit about 30% more electricity than lead-acid batteries. 8. Voltage platform: The voltage platform of lithium batteries is u003e3V, lead The second thing worth saying about acid battery is 2V is that lead-acid battery is safe, and lithium battery is also safe, because lithium itself is very active, so it is still a problem. Therefore, although lithium batteries have advantages in performance and various aspects, the usage of lithium batteries is generally not low. Therefore, almost all users and integrators will choose lead-acid batteries from an economic point of view.
