BYD Battery-Box HVB Battery Module 2.97kWh 51.2V LFP (Single Module)

Single BYD Battery-Box HVB expansion module (2.97 kWh, 51.2 V, 27.3 kg) for building or extending an HVB tower system. HVB towers are configurable from 2 to 10 modules per tower. Uses cobalt-free LFP cells and supports BYD’s modular concept to extend anytime at any SOC (system/inverter dependent). The BYD Battery-Box HVB module is the building block of BYD’s newest-generation high-voltage LFP storage platform. Each module adds capacity to an HVB tower and integrates via BYD’s patented internal plug connection for fast, clean stacking and service-friendly installation. BYD specifies you can extend anytime at any SOC (platform feature). BYD positions HVB as a professional-grade ESS platform using cobalt-free LFP cells developed in-house and a solid die-casting case for robust long-term deployments. Why buy a single HVB module: Expand an existing HVB tower by adding capacity (within the allowed HVB tower module count). Replace a module in an HVB installation (service/maintenance scenario). Keep system growth flexible: BYD highlights modular design and 'extend anytime' behavior (platform feature). Technical specifications (single module): Model: BYD Battery-Box HVB Module. Energy (per module): 2.97 kWh. Nominal voltage (per module): 51.2 V. Weight (per module): 27.3 kg (also noted as '1 module < 30 kg' on the feature page). Cell chemistry: Lithium Iron Phosphate (LFP, cobalt-free). System requirements and compatibility (critical): HVB towers are built from 2 to 10 modules per tower. One module is not a complete tower/system. HVB systems require the correct HVB BCU / Power Module and must be paired with a supported high-voltage hybrid/battery inverter using the required module count / voltage window for that inverter. Platform reference: communication interfaces are CAN / RS485 (implemented at system level with compatible inverters). What’s included: 1× BYD Battery-Box HVB battery module (2.97 kWh / 51.2 V / 27.3 kg). Not included (sold separately): HVB BCU / Power Module, base/interconnect parts, and complete tower kits (2–10 modules). Inverter, communication/accessories, monitoring modules (where applicable).
