Lithium battery function parameters:
Model: 70AH
1. 70AH, ABS engineering plastic sealing, lithium iron phosphate battery, life span of 10 years, long service life;
2. Strong high and low temperature adaptability, adapt to the ambient temperature range of -10℃ to 45℃;
3. With overcharge, overdischarge, and overcurrent protection functions;
4. Equipped with a waterproof housing that can be hung;
5. Lithium batteries have relatively high energy and high storage energy density.
Early solar street lamp energy storage batteries were mostly gel or lead-acid batteries, most of which were buried underground, and are now being replaced gradually. With the continuous maturity of lithium battery technology, construction units have begun to gradually adopt lithium battery energy storage technology, so the advantages and precautions of lithium battery energy storage:
First, the lithium battery is nearly fully discharged, and the marked capacity can be fully utilized;
Secondly, the lithium battery is light in weight and can be placed on the upper part of the light pole for easy installation and maintenance;
Third, the design of the lithium battery capacity can be appropriately reduced, which can be reduced by 30%-50%. Taking into account the large design power of the original battery board, the charging time can be greatly reduced.
It is also necessary to pay attention to the issue of keeping warm in winter (northern) when replacing lithium batteries. Insulation cotton can be protected to ensure normal charge and discharge in winter.
