What is lifepo4 battery and why choose Benergy lifepo4 battery?
A LiFePO4 battery, short for Lithium Iron Phosphate battery, belongs to the category of lithium-ion rechargeable batteries. It operates at a single voltage of 3.2V and can possess a capacity range from 90mAh to 300Ah.
LiFePO4 batteries stand out as the safest lithium battery variant currently accessible in the market. They exhibit characteristics such as lighter weight, smaller dimensions, extended cycle life, low maintenance requirements, absence of pollution, and no memory effect. Consequently, they can effectively substitute lead-acid batteries as well as Ni-MH/Ni-CD batteries.
Benergy has been manufacturing and exporting LiFePO4 cells since 2009, offering globally recognized battery solutions renowned for their quality, dependability, and safety.

Q4: Are your factory or trading company?
A4: We are proffesional Lifepo4 cells and packs manufacturer with our own factory and brand BENERGY. We provide all kinds of OEM/ODM services for clients around globe.
Q5.What is your warranty?
A5:We offer 2 years warranty for all our battery pack.we ensure at least 2000 cycle life for the LiFePO4 battery pack, which means,after 2000@80% DOD,there will still around 60% capacityt left.You can use it for at least 5 years for normal 1 time charge and discharge everyday.
Q6.Can we put 12V LiFePO4 battery pack in parallel or series by ourself?
A6:Yes. The battery can be put in parallel by customers. But there are few tips we need to pay attention:
1> Make sure the voltage of each battery are same before put inparallel. If they are not same, charge them to the same rate;
2> Do not put discharged battery and undischarged battery in parallel. This may reduce the capacity of the whole battery pack;
3> Do not put the 12V batteries in series.
4> If you are not professional in parallel batteries, please don't handle the battery by yourself. It may cause danger and hurt the cycle life of battery;
5> If you want to make a higher capacity battery pack, like 12V 200Ah, pls order 12V 200AH directly. The cost for one 12V 200AH is lower than two 12V 100AH pack. To charge or discharge one 12V 200Ah directly is better than to charge or discharge two 12V 100AH packs, cycle life longer, safer.
