What is an Lifepo4?

LiFePo4 battery mean lithium Iron Phosphate battery which is a kind of lithium ion rechargeable battery. The single voltage is 3.2V and capacity can be 90mAH to 300AH.


LiFePo4 batteries are the safest lithium battery type currently avaliable on the market today. With characteristic of lighter weight, smaller size, longer cycle life, free maitainance, no pollution, no memory effect they can fully replace lead acid batteries and Ni-MH/Ni-CD batteries.


Benergy has been producing and exporting Lifepo4 cells since 2009 and we have been providing quality, reliable and safe battery solutions worldwidely.
