Innovative “plug-and-play” stacking technology, no complex configuration required, can flexibly combine 2-4 batteries to meet flexible energy storage needs from small residential to commercial projects.
✅ Military-grade safety, durable and long-lasting
Lithium iron phosphate (LiFePO4) battery cells with a cycle life of ≥6,000 cycles, maintaining over 80% capacity after 10 years.
IP65 protection rating + intelligent BMS protection, real-time monitoring of voltage, temperature, and current, eliminating risks of overcharging, over-discharging, or short circuits.
✅ Smart energy management, saving energy and peace of mind
Supports multi-source input from solar power, the grid, and generators, automatically switching to the optimal power supply mode.
🏠 Home energy storage | Pair with a photovoltaic system to achieve zero electricity bills and worry-free power outages.
🏪 Commercial backup power | Ensures 24/7 uninterrupted operation of critical equipment in supermarkets, clinics, and data centers.
🚐 Off-grid power supply | Provides stable, clean energy for RVs, boats, and remote workstations.
Founded in 2011, Shenzhen Haisic Technology Co., Ltd. is a national high-tech enterprise dedicated to the research, development, and production of energy storage products such as LiFePO4 battery packs, commercial& industrial energy storage residential energy storage, portable power station/solar generator, solar inverter, lift truck battery, RVAlandscape bus/golf cart battery and other OEM/ODM battery in China.
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.
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.
