Professional R&D team covering Structural Design, Electrical Design, Fluid Simulation Design, Professional Matching of BMS and PCS, and comprehensive Verification Tests. Our team of mechanical, BMS, electrical, application, and technical support engineers ensures a reliable, one-step energy storage solution from custom design to mass production.
With 37 integrated production processes and 7 steps of rigorous quality verification, we maintain high standards of stability. Our complete quality control system covers incoming material verification, in-process checking, and final output inspection. We perform 100% full testing and aging cycles on all units.
To better ensure the safety of your goods, professional, environmentally friendly, convenient and efficient packaging services will be provided.
Our batteries are exceptionally safe. All units utilize stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS). The BMS protects the cells against excessively high or low voltages, high currents, short circuits, and extreme heat or cold to prevent battery failures.
For standard 12V, 24V, or 48V systems, LiFePO4 (Lithium Iron Phosphate) is the optimal choice. The voltage is highly compatible with AGM setups and integrates with components in RVs, boats, off-grid systems, solar home applications (such as refrigerators, air conditioners, and washing machines), telecommunication towers, and hybrid solar energy setups.
Yes, they support parallel connection (up to 15-16 units depending on configuration) to scale system capacity, allowing for energy storage configurations up to 150kWh+.
Yes, our battery packs are compatible with most major brands of inverters on the market, including Deye, MUST, SMA, Growatt, Solax, Solis, Sungrow, Sofar, Voltronic, Sorotec, Studer, and others.
The BOX40S series features premium LiFePO4 cells designed to deliver over 6,000 charge and discharge cycles at 80% Depth of Discharge (DOD), ensuring long-term operational efficiency and system durability.
The built-in BMS actively monitors and balances the individual cells. It acts as a safety shield, protecting the entire battery system from common hazards like over-charging, over-discharging, short circuits, and thermal runaway.
