Fogstar Energy IP65 16.1kWh LiFePO₄ Battery — 51.2V 314Ah
Engineered for serious off‑grid, backup and commercial duty, the Fogstar Energy IP65-Rated 16.1kWh LiFePO₄ battery delivers dense, dependable storage with safety and control built in from the cell upwards. The integrated fire suppression and active battery heating make cold garages, plant rooms and unheated outbuildings viable installation locations — a practical necessity for UK off‑grid projects year-round.
Key features
- 16.1kWh LiFePO₄ storage, 51.2V nominal, 314Ah — suited to residential, agricultural, commercial and light-industrial off‑grid and backup systems.
- PACE 200A BMS with 2A active balancer for precise cell management, stable operation at high currents and extended service life.
- IP65-rated enclosure — dust-tight and splash-protected, suitable for outbuildings, plant rooms and external battery enclosures.
- Built-in heater activates below 5°C, enabling safe charging down to 0°C and reliable discharge to −20°C.
- Factory-fitted aerosol fire suppression, heat-activated at 170°C — rapid localised response without external systems.
- Scales to 15 units in parallel, supporting multi-day autonomy and larger commercial installations on a shared DC bus.
- 10-year warranty covering BMS failure, cell failure, temperature sensors, charge/discharge faults and internal corrosion.
- 15-year design life — aligns with long-term off‑grid and commercial project horizons.
Designed for real-world UK conditions
The integrated heating system keeps cells within safe operating limits, enabling charging at 0°C and discharge to −20°C — so unheated agricultural buildings, roadside cabinets and remote plant rooms remain viable year-round. A factory-fitted aerosol suppression unit inside the enclosure provides rapid localised response to thermal events at 170°C, without dependency on external detection or suppression infrastructure.
A 250A onboard breaker and dedicated isolation switch simplify safe working and routine maintenance. At 128.8kg, installation requires appropriate mechanical handling; at 500 × 232 × 915mm the unit has a practical footprint for battery rooms with limited floor space.
System integration and control
The PACE 200A BMS manages protection, charge and discharge limits, and communications across CAN, RS485 and RS232 ports. Pre-loaded inverter protocols cover Victron, Luxpower, Sofar, Solis, Sunsynk and more — selectable via the onboard LCD touchscreen without additional software or firmware tools, keeping commissioning time low on remote sites.

Cabling, scalability and supply
Each unit is supplied with 1.5m battery cables with Amphenol connectors for battery-to-battery parallel linking, a 1.5m RS485/CAN communication cable, and a 1.8m PC cable for diagnostics and setup. Always connect negative conductors before positive. Up to 15 units can be connected in parallel — these batteries cannot be connected in series or mixed with other chemistries.
