Advantage of LiFePO4
Lithium iron phosphate batteries (LiFePO4 or LFP) offer lots of
benefits compared to lead-acid batteries and other lithium
batteries. Longer life span, no maintenance, extremely safe,
lightweight, improved discharge and charge efficiency, just to name
a few. LiFePO4 batteries are not the cheapest in the market, but
due to a long life span and zero maintenance,which means that you
don't need to replace in a long time,you can enjoy the convenience,
it’s the best investment you can make over time.

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 -5 years warranty for all our battery pack.we ensure
at least 3000 cycle life for the LiFePO4 battery pack, which
means,after 3000@80% DOD,there will still around 80% capacityt
left.You can use it for at least 5 years for normal 1 time charge
and discharge everyday.
Q6.Can we put 48V 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 48V
200Ah, please order 48V 200AH directly. The cost for one 48V 200AH
is lower than two 48V 100AH pack. To charge or discharge one 48V
200Ah directly is better than to charge or discharge two 48V 100AH
packs, cycle life longer, safer.
