12V 40AH Lifepo4 battery pack for solar system, can integrated with 70W solar panel and charger controller. 

With excellent safety, light weight, small size, stable performance and extremly long cycle life, Benergy Lifepo4 battery is proved to be the most suitable battery to replace lead acid battery for solar system applicatoin.

Advantages of Benergy Lifepo4 batteries:

1. High energy density: Compared with the same capacity lead-acid battery, LiFePO4 battery is 1/3 smaller in size, 2/3 lighter in weight, 5 times longer in cycle life, more economic and eco-friendly.Compared with same capacity Li-NixCoyMnZ battery, LiFePO4 battery is 2.5 times longer in cycle life, also most the same in weight & size.

2.Stable performance: Can bear float charge as lead acid battery do, which is very important for solar system. (Other types of lithium battery is easy to get bloating after long time floating charge). 

3. 100% safety.Benergy LiFePO4 is an intrinsically safer cathode material than Lithium-ion since exothermic reactions can not occur in batteries based on this material LiFePO4 cells do not incinerate or explode under extreme conditions. 

4.Extremly long cycle life: More than 2000 cycles and is several times greater than Ni-MH, Ni-Cd or lead-acid.

5.Environmental friendly. No toxic, or polluting material(such as lead, cadmium, mercury) is contained in lithium battery, which is a kind of green battery.

For many applications, our battery systems cost is even lower than lead acid because lighter-weight, longer-life batteries means fewer replacements, reduced maintenance and service costs, less shipping and material handling costs, and lower total inventory carrying costs.
