Fogstar Drift Gen2 24V 334Ah LiFePO4 Leisure Battery High‑capacity 24V 334Ah LiFePO4 leisure battery (8,038Wh) for larger off‑grid, marine and commercial systems needing efficient 24V power. Integrated smart BMS with 300A discharge capability, low‑temperature heating and protection functions for controlled, year‑round operation. Up to 4,000 cycles at 80% depth of discharge, helping reduce replacement intervals and downtime in logistics, welfare and industrial applications. Fogstar Drift 24V 334Ah Gen2 LiFePO4 Leisure Battery The Fogstar Drift Gen2 24V 334Ah LiFePO4 leisure battery is designed for systems that are built around a 24V bus, providing 8,038Wh of stable energy storage in a single compact unit. Using EVE LF334 prismatic cells and a 300A BMS, it can support sizeable inverters, motors and DC loads where a 24V architecture improves efficiency and cable sizing. This makes it a strong option for marine house banks, commercial vehicles, off‑grid cabins, site cabins and containerised power solutions where dependable long‑term performance is essential. Key features 24V 334Ah (8,038Wh) LiFePO4 leisure battery using EVE LF334 Grade A prismatic cells for reliable, large‑scale storage on a 24V bus. 300A maximum discharge and 300A maximum charge rating, suitable for high‑load systems when correctly engineered with appropriate cables, fusing and control equipment. Smart BMS with overcurrent, overdischarge and temperature protection, plus 2A active balancer to maintain cell voltage alignment over time. Built‑in heater pads that warm the battery to enable charging in cold conditions, powered by the incoming charge current rather than the battery itself. 24V models can be linked: up to sixteen units in parallel or two in series (48V maximum), providing flexibility for larger off‑grid and commercial systems; professional installation is recommended for multi‑battery banks. Ideal applications This 24V 334Ah Gen2 LiFePO4 leisure battery suits marine house banks, larger campervans, off‑grid cabins and commercial vehicles that are already set up for 24V equipment. It is also well suited to site cabins, welfare units, telecoms support and containerised power packages where a 24V system helps reduce current and cable sizes while supporting substantial inverter loads. For systems combining multiple batteries, mixed charging sources (solar, alternator, chargers) or larger inverters, we recommend design and installation through our trusted partners or your preferred qualified installer.

Battery heating This battery has a built-in heater that heats the battery to 5°C to enable charging at low temperatures. The Drift heating pads are only activated when the battery is being charged, and are only powered by the incoming charge current, not the battery itself. If you put the battery on charge in cold temperatures, it will heat the battery first, and then allow current through to the battery when the temperature is safe enough to do so. Battery safety Do not disassemble your battery. Do not short the battery. Do not store your batteries in direct sunlight. Store the battery in a cool and well ventilated area. Keep batteries away from flammable objects and materials. Keep batteries away from static electric charges. Keep out of reach from animals and children. Do not immerse your battery in water. Do not crush, incinerate or modify your battery. Only use batteries within the manufacturers specifications. Recycle your batteries correctly. Storing your battery We strongly suggest your batteries are stored at room temperature, charged to about 30% to 50% of capacity. We recommend that batteries be charged once every three months to prevent over discharge. Battery performance Because Lithium Iron Phosphate batteries utilise a chemical reaction, battery performance will deteriorate over time even if stored for long periods of time without being regularly used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges, the life expectancy of the battery may be shortened, or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery. Charging Your battery should be charged using a lithium iron phosphate battery charger. Bulk Charge: 28.8V Float Charge: 27V Charging Current: up to 300A Battery warranty Fogstar offers a 10 year warranty on all Fogstar Drift Leisure batteries. Warranties only apply to the original owner and are non-transferrable. Fogstar will verify your purchase prior to processing any warranty claims or returns. Please contact us at [email protected] as soon as you encounter any issues. Our warranty does not cover items that have been damaged due to gross negligence, normal wear and tear, damage due to accident or collision, abuse or incorrect installation. Download the Fogstar Drift App As a Fogstar customer, you'll also get the use of our fantastic Fogstar Drift App. Our App has been custom built to connect directly with the BMS, allowing you to manage and maintain the health of the battery at all times. The Fogstar Drift app is free to download on both Android and iOS. Active balancing All cells used in the Gen2 range are Grade A, factory-matched and balanced EVE prismatic cells. - supplied directly from the manufacturer. This ensures your battery begins life with optimal uniformity in capacity and internal resistance. The 2A active balancer is fully integrated within the BMS architecture, rather than implemented as an external module. It engages only when cell deviation exceeds the defined threshold of 0.015V, and operates with minimal power draw. The system maintains long-term voltage equilibrium across the pack without continuous current consumption, and without requiring any user intervention.
