BYD B-Box Premium HVM 13.8 kWh Lithium Battery

Product Description

The BYD B-Box Premium HVM 13.8 kWh Lithium Battery is a high-voltage tower composed of 5 HVM modules of 2.76 kWh on a Base and managed by the BCU. It provides 13.8 kWh usable with a nominal voltage of 256 V, LFP technology (LiFePO₄, cobalt-free), and a modular, safe, and efficient design (≈96 % round-trip) with IP55 protection rating. Thanks to its CAN/RS485 communication with BYD profile, it integrates natively with the main hybrid/grid HV inverters on the market.

Main Features

• Usable capacity: 13.8 kWh (5× HVM 2.76 kWh).
• Nominal voltage: 256 V (typical range 200–300 V).
• Chemistry: LiFePO₄ (LFP), safe and cobalt-free.
• Current: 50 A continuous; 75 A peak 5 s.
• Round-trip efficiency: ≈96 %.
• System protection: IP55 (indoor/outdoor protected).
• Plug-in connection between modules, no internal wiring.

Advantages or Benefits

• Modular and expandable: add or reconfigure modules to grow up to 22.1 kWh per tower.
• Superior safety: LFP chemistry with BCU that coordinates SOC/SOH and events.
• Wide compatibility: CAN/RS485 integration with single-phase and three-phase HV inverters.
• Clean installation: Robust Base and organized architecture that reduces time and errors.

Purpose or Applications

Ideal for residential and commercial self-consumption, systems with high-reliability back-up, and off-grid projects that require high, stable voltage, solid power response, and maximum safety.
