Look at the Dyness B3.
The Dyness battery module B4850 is widely used in energy storage and back-up power systems. For new energy storage, from distributed household energy storage systems to centralized power station energy storage system, B4850 plays an excellent role for its modular design. For back-up power systems, module-based systems can be irreplaceable both in grid or off-grid.
