Fogstar Drift 12V 334Ah Gen2 Lithium Leisure Battery
The Fogstar Drift 12V 334Ah Gen2 gives caravan, motorhome, campervan and boat users a strong lithium upgrade. It uses Grade A LF334 EVE LiFePO4 cells and gives you 4,275Wh of energy. As a result, you can run key 12V items for longer while you stay away from mains power.
334Ah Power for Longer Off-Grid Stays
This 334Ah lithium leisure battery suits high-use 12V systems. For example, it can help run lights, pumps, a fridge, USB charging, heater controls, small tools, marine kit and inverter loads. Therefore, it works well for trips, weekends away and longer off-grid stays.
Great for Caravans, Motorhomes and Campervans
This battery gives leisure vehicle users more usable power than many lead-acid options. Also, it helps reduce weight and improves power use. As a result, caravan, motorhome and campervan users can build a stronger and more useful 12V setup.
Strong Choice for Boats, Cabins and Solar Setups
Boat owners and off-grid users can also use this battery for steady 12V power. In addition, the IP67 rated case helps protect it from dust and water. Therefore, it suits marine spaces, damp lockers, cabins and solar energy storage systems.
300A Smart BMS for High-Demand Loads
Fogstar fits this battery with a 300A Smart BMS. Because of this, the battery can handle heavy loads and support powerful inverter setups. Also, the BMS helps protect the battery while it charges and discharges.
Accurate Power Tracking with Bluetooth
You can check key battery data through the Fogstar Drift App. For example, you can track voltage, current, state of charge and temperature from your phone. As a result, you can manage your power system more easily while touring, camping or boating.
Active Cell Balancing for Better Performance
The built-in active balancer helps keep the cells aligned. Therefore, the battery can work more smoothly and keep a steady output over time. In addition, this feature helps support long-term battery health.
Built-In Heating for Cold Weather Charging
The built-in heater warms the battery before charging in cold weather. As a result, it helps protect the cells when the temperature drops. However, you should still use a lithium-ready charger for the best and safest results.
Built for Tough Leisure Use
The Drift 334Ah Gen2 uses a strong case, upgraded terminals and a built-in on/off switch. Plus, Fogstar backs the battery with UK support and a 10-year warranty. Finally, this makes it a strong choice for users who want long-term off-grid power.
