LiFePo4 battery could be one of the best solution for solar street lighting because of its unique advantage comparing to lead acid or gel battery .
Very Long Cycle Life
FGE’s LeFePo4 battery could reach 2000 DOD (Depth of Discharge) cycles but still Remaining 70% initial capacity, comparing to traditional lead acid battery with only average 300-500 cycles or some very best with 1000cycles
Safety
LiFePo4 battery is not Li-ion battery that used in our cell phone or mobile device that has explosion risk in extreme condition such as crash , burn or threw into fire etc. LiFePo4 has been proved by industry as very stable and safe chemistry structure and has very minimum risk to cause safety accident even in the most extreme condition.
High Energy Density
In the same volume, LiFePo4 has much higher capacity than lead acid battery because of its higher energy density. It could save a lot of volume and weight in the design and also save the transportation cost
