2.56kWh 25.6V Wall Mounted LiFePO4 Battery with CAN RS485 Communication
This wall mounted LiFePO4 battery provides 2.56kWh of nominal energy on a 25.6V, 100Ah platform. It is designed for home solar storage, UPS backup, communication equipment and other low-voltage projects that require compact battery installation without occupying valuable floor space.
The battery works as the DC storage section of the system and requires a compatible external inverter or charger. Its integrated BMS, communication interfaces and parallel capability support projects ranging from one battery module to a larger low-voltage storage bank.
The 25.6V battery platform is intended for compatible 24V-class inverter and DC systems. Its 22.4–29.2V operating range should be checked against the selected inverter, charger and connected equipment before ordering.
The wall-mounted enclosure measures 336 × 360 × 181mm and weighs approximately 28kg. The supporting wall, mounting hardware, cable route and service clearance should be reviewed before installation.
The battery stores 2.56kWh of nominal DC energy. It can support lighting, routers, computers, communication devices and other selected loads when paired with a suitable inverter.
The rated charge and discharge current is 50A. The product sheet also lists 100A continuous current and 105A for 10 seconds, with 1.28kW rated power, 2.56kW continuous power and 3.07kW for 10 seconds.
Actual operating current and power may be lower according to temperature, battery state of charge, inverter limits and the complete project design.
RS485, RS232 and CAN interfaces provide communication options for compatible inverter and monitoring equipment. The inverter model and supported battery communication method should be confirmed before ordering.
The specification recommends six batteries in parallel and lists support for up to sixteen units. Capacity expansion should be planned together with the inverter, cables, protection devices, busbar arrangement and battery addressing.
The product sheet lists Bluetooth as optional and Wi-Fi as a remote-data option. The supplied monitoring configuration should be confirmed during quotation.
The IP21 enclosure is intended for a dry indoor or protected technical location. The battery should remain protected from rain, water exposure and condensation, with access provided for the bottom cable outlet.
The operating range is 0°C to 50°C during charging and -10°C to 60°C during discharging. Rated current and power may vary with temperature and battery state of charge.
The inverter, charger, solar array, mounting hardware and external electrical protection are selected separately according to the project.

Choose an inverter or charger that supports a 25.6V lithium battery, the 22.4–29.2V operating range and a compatible communication protocol.
Yes. The specification recommends six units in parallel and supports up to sixteen units when the complete system is compatible.
Bluetooth is listed as optional, while Wi-Fi is listed as a remote-data option. Confirm the supplied monitoring configuration during quotation.
That depends on the inverter, connected loads, daily energy use and required backup period. The 2.56kWh rating is nominal DC battery energy.
Provide the inverter model, load list, required backup time, expected battery quantity, installation layout and communication requirement.
Send the inverter specification, daily energy requirement and available wall space. We will review voltage compatibility, module quantity and communication options for the project.
