Charging mode
1. solar charging only: photovoltaic charging only, without
starting mains charging, the most energy-saving way 2. Photovoltaic
priority: Photovoltaic priority charging, starting mains charging
only when photovoltaic fails.
3. commercial power priority: commercial power gives priority to
charging, and photovoltaic
charging is started only when commercial power is invalid.
4. Hybrid charging: Hybrid charging of photovoltaic and commercial
power, giving priority to
photovoltaic, commercial power supplement, the fastest way.
Output way
1. Photovoltaic priority: Photovoltaic+battery power supply,
maximizing the use
of solar energy while maintaining battery energy.
2. commercial power priority: commercial power is given priority,
and uninterrupted.
3. backup UPS is started when commercial power is invalid.
Inverter priority: maximize the use of DC power.

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.
Why choose Benergy 48V Lifepo4 battery pack?
The Benergy 48V 150Ah is a Lithium Iron Phosphate battery (LiFePO4)
with a rated capacity of 150Ah. The unique combination of
state-of-the art technology and smart software makes this lithium
battery a robust, safe and easy to use energy storage solution.
Compared to conventional lead-acid batteries, the Benergy 48V 150Ah
lithium battery offers an enormous weight and space saving. It is
very efficient, has extremely high performances and is maintenance
free.
FAQ:
Q1: Can I get free sample?
A1: Generally we don't provide free sample, but we can return
sample cost when the buyer plant a bulk order.
Q2: How should I pay?
A2: You can pay via T/T, PayPal, Western Union, Cash etc., 100% T/T
in advance for samples. For large quantities, 30% T/T in advance as
soon as order confirmed and the balance before shipping via T/T or
L/C etc. If you prefer other payment terms, please contact us
freely.
Q3: What is delivery time if we place an order?
A3: It depends order quantities. Usually, we can deliver goods
within 10 -15 working days for small orders, for more QTY. order,
let's confirm when you place offical order.
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.
