Purpose-built for Fiat Ducato, Citroën Jumper, Peugeot Boxer and Ford Transit camper conversions, the WattCycle 12V 314Ah Caravan Leisure Battery combines high energy capacity, intelligent battery management and a compact seat-base design. Whether you're touring across Europe, camping off-grid or travelling through winter, it delivers dependable power.
High-demand appliances place significant stress on a battery. A robust 250A BMS which supports continuous loads up to 3,200W helps ensure stable power delivery while protecting both the battery and connected equipment.
Cold temperatures can prevent LiFePO4 batteries from accepting a charge. WattCycle 12V 314Ah Caravan Leisure Battery has internal heating pads, bringing the battery to an appropriate charging condition before charging begins, reducing interruptions during winter adventures. This feature supports safer winter operation during skiing trips, mountain camping and cold-season travel.
Whether you're driving through mountain passes, gravel roads or long-distance European tours, the reinforced construction is designed for demanding campervan environments. A durable metal case provides additional protection against impacts and everyday use. The internal metal frame helps maintain internal structural stability and minimise cell swelling over long-term use. Removable handles and top cover (fixed by screws) ensure more flexibility during the journey.
Many high-capacity lithium batteries become too tall for European campervan seat bases, and lead-acid batteries provide only half usable energy while taking more space. The 12V 314Ah Caravan Leisure Battery was designed differently. It fits under many European campervan seats perfectly to save valuable storage space on your trip.
A single battery with 4019Wh usable energy can typically support 2–3 days of off-grid camping (depending on your energy consumption), making it ideal for weekend escapes and longer European road trips. Instead of worrying about campsite hook-ups, you can enjoy the freedom to power the appliances you use every day.
This 12V 314Ah battery supports configurations of up to 4 batteries in parallel and 4 in series (4P4S), for a total usable energy of 64.30 kWh. Regardless of how your energy grows, your battery system can grow with you straightforwardly.
It can be used not only in campervan living but also provides reliable off-grid electricity without relying on campsite hook-ups.

Yes. The WattCycle DISCOVER 12V 314Ah Caravan Leisure Battery features a Bluetooth interface with password protection, allowing you to monitor the battery status and manage additional functions.
Using the WattCycle App, you can monitor the following data (for reference only; actual data may vary depending on the app version): status, temperature, voltage, current, and individual cell voltages.
You can also control the charging and discharging processes of the battery directly via the app.
Yes. The battery features Bluetooth connectivity and works with the WattCycle App, allowing you to monitor key battery information in real time from your smartphone.
You can check the basic parameters like voltage, current, power, or temperature. The WattCycle App also supports modifying the parameters by yourself. But keep in mind that always contact us first to confirm if the parameter can be changed for safe use.
Yes. Our 250A BMS protects against charging or discharging in unsafe temperatures.
We recommend using a WattCycle LiFePO4 battery charger, which is specifically designed to meet the unique charging needs of LiFePO4 batteries. Alternatively, you can also charge the battery using photovoltaic solar panels through MPPT or use an inverter with a built-in AC to DC charging function.
No, this battery cannot start the car. However, it can be used as an auxiliary battery for the car.
Yes. The housing of the WattCycle 12V 314Ah Caravan Leisure Battery is removable.
However, please note: If you make any unauthorised modifications to the internal structure of the battery without consulting customer service, and this leads to an incident, WattCycle will accept no liability, and the warranty will be void.
