Stackable home battery & High-capacity modular battery : Stackable Battery

Introducing the WRES-L-25-048 Energy Storage Battery, a high-performance solution for reliable energy management. It offers a rated capacity of 945Ah, a voltage range of 44.8-57.6Vdc, and supports 700A charge/discharge current, with an efficiency of 90%.
Comprehensive safety protections include over-voltage, over-current, short-circuit, low-voltage, and over-temperature safeguards, plus cell balance technology. It features a Bluetooth/button-controlled screen (wall-mounted type) and supports CAN/RS485 communication for easy integration and monitoring.
Designed for flexibility, it can be wall-mounted or stackable, with dimensions of 6601164450mm and a weight of 458KG. With an IP20 rating, it’s suitable for indoor use (5%-95% RH, no condensing), operating in -20℃ to 55℃ and altitudes ≤2000m. Boasting a 15+ year lifespan at 25℃, this battery is ideal for industrial, commercial, and residential energy storage, delivering efficiency, safety, and durability.
