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.

Product Advantages
1. Long cycle life. More than 2500 times (charge and discharge at 1C, 80% capacity retention after 2500 cycles);
2. Compact in size and light in weight. 1/3 smaller in size, 2/3 lighter in weight than lead acid battery.
3. High safety: No fire and explosion in overcharge test; No explosion, no fire under collision, over charged or short circuit.
4. Good charging and discharging performance. 3C continous discharge and 10C burst.
5. Full green and no pollution. All raw material of the batteries are environmental-friendly,
6. Wide working temperature range: From -20℃ to 60℃, extremely cold and hot weather will not affect its performance.
7. Bar Code management system. All data is managed by system, we can trace the cell information and match every pack with closest data.
8. Produced with automatic equipments.

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 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.
