Solar Energy Storage Battery Description :


Specification - Voltage: 12v; Amp: 20Ah; Dimension: 7.16*3.03*6.10inches (L/W/H); Weight: 2.45kg/5.4lbs.


Flat Discharge - LiFePO4 technology gives a very flat discharge curve which means sustained power to the end of the cycle. If you are powering lights they will remain brighter for longer, giving you sustained performance.this LiFePO4 battery applicate better for Energy Storage system.


Our experienced team utilizes proven technology and innovative engineering to design, assemble, and test rechargeable Solar Energy Storage. We support high and low volume manufacturing for a diverse customer base that includes some of the most recognized companies in the world. Whatever the power requirements of your mobile or portable Equipment, we have the ideal batteries solution.


5000 Charging Cycles - Lead-acid batteries last 100-300 cycles is a lot more typical while lithium-iron batteries will go 5000 cycles with no problem. Lithium batteries can be fully discharged without risk and without loss of future capacity as well.


Products through UL, CE, FCC, RoHS certificated.
