With 4,275Wh of energy, 300A maximum discharge and a robust smart BMS, it provides a stable power supply for inverters, refrigeration, tools and onboard electronics over long duty cycles. Built‑in heating, Bluetooth connectivity and proven EVE LF334 prismatic cells make it a practical choice for logistics, commercial and industrial projects where predictable performance and simple monitoring are important.\u003c\/p\u003e\n\n\u003ch2 style=\"text-transform: uppercase;\"\u003eKey features of the Fogstar Drift 334Ah Gen2\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli style=\"font-size: 16px !important; margin-bottom: 8px;\"\u003e12.8V, 334Ah (4,275Wh) LiFePO4 leisure battery using EVE LF334 Grade A prismatic cells for stable, long‑life energy storage.\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important; margin-bottom: 8px;\"\u003e300A maximum discharge and 300A maximum charge capability, suitable for high‑load systems when correctly designed and protected.\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important; margin-bottom: 8px;\"\u003eIntegrated smart BMS with over‑current, over‑discharge and temperature protection plus 2A active balancing for cell health over the battery lifetime.\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important; margin-bottom: 8px;\"\u003eBuilt‑in low‑temperature heating pads to enable safe charging in cold conditions, powered from the incoming charge current rather than the battery itself.\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important; margin-bottom: 8px;\"\u003eSeries and parallel linking: up to 16 batteries in parallel or 4 in series (up to 48V), allowing flexible system design for larger off‑grid and commercial installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eIdeal applications\u003c\/h2\u003e\n\u003cp style=\"font-size: 16px !important;\"\u003eThis 334Ah Gen2 LiFePO4 leisure battery suits campervans, motorhomes and overland vehicles that run high‑demand loads such as inverters, induction hobs, refrigeration and heating for extended periods away from mains power. It is equally at home as a marine house bank on yachts and workboats, or in static off‑grid systems such as site cabins, containerised power units and backup systems for small commercial premises. Multiple batteries can be combined for larger 12V, 24V or 48V systems and integrated with solar arrays, alternator charging and inverters using appropriate control equipment; for anything beyond a simple drop‑in replacement we recommend installation and commissioning by one of our trusted partners or your preferred qualified installer.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eCell Type: LF334\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eCell Configuration: 4S1P\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eNominal Capacity: 334Ah\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eEnergy: 4,275Wh\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eCell Chemistry: Lithium Iron Phosphate\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eCell Nominal Voltage: 3.2V *4 (12.8V)\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eCycle Life: 4000 Cycles @ 80% DOD\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eMaximum Discharge: 300A\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eNominal Voltage: 12.8V\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eStandard Charging Voltage: 14.4V\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eMaximum Charging Voltage: 14.6V\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eDischarge Cut Off Voltage: 10V\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eDischarge Temperature Range: -20°C ~ 55°C\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eCharge Temperature Range: 0°C ~ 55°C\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eHeating Function: 0°C ~ 10°C\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eStorage: -20°C ~ 45°C (1 month) \u003cbr\u003e 0°C ~ 35°C (3 months)\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eMeasurements (LxWxH mm): 383 x 193 x 250\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eWeight: 29kg\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eHousing Material: ABS Plastic\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBMS specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eMaximum Discharge: 300A\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eTemperate Protection: Yes\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eOvercurrent Protection: Yes\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eOverdischarge Protection: Yes\u003c\/li\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eMax Charging Current: 300A\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBattery series and parallel mode\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli style=\"font-size: 16px !important;\"\u003eOur 12V models can be connected sixteen (16) in parallel OR four (4) in series -
