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.
