FAQ 
1.What is special about lithium batteries?
A: With high energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. Long service life, life span can reach more than 6 years. Light weight, the weight is about 1/5-6 of the lead-acid product under the same volume.

2. What is a lithium battery used for?
A: Lithium battery is used for power and energy storage. Like emergency power backup or UPS. Dependable electric and recreationalvehicle power, golf cart, reliable and light-weight marine, solar power storage, solar house, small processing factory, surveillance or alarm systems in remote locations.

3.Are your batteries safe?
A: Our batteries are safe. All Zwayn batteries use the safest and most stable components, including a LiFePO4 cathode and abuilt-in Battery Management System (BMS). The BMS protects the cells against excessively high or low voltages, high currents,short circuits, and excessive heat or cold. These are the most common causes of battery failures, and we have taken everyprecaution to mitigate these risks in all of our batteries.

4.How do I choose the correct lithium deep cycle battery for my application?
A: In most standard 12, 24, or 48 volt systems, the best choice of lithium battery is LiFePO4 (Lithium Iron Phosphate/
Pouch/Primary battery cell). The voltage of this type of battery is very similar to an AGM and will work great with readily
available system components for your RV, boat, off-grid power system, solar house(TV, refrigerator, washing machine, air
conditioner, water heater, microwave oven, induction cooker, dishwasher, printer, computer),Telecommunication Tower, hybrid &off-grid solar energy system applications.

5.Can it be series or parallel for use?
A: Yes sir, it can support max. 15 in parallel connection for use, Max 150kwh storage box.

6.Can these battery pack be compatible with my inverter? do you have a company list of the inverter which iscompatible? 
A:Yes sir, our battery pack can compatible with most brand of inverter on the market, such as Deye, MUST, SMA, Growatt, Solax,Solis, Sungrow, Sofar, Voltronic, Sorotec, Studer, etc.
