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.

Buena calidad, tengo otra igual, colocada en la misma autocaravana
Estoy contento con la batería tiene unas medidas muy compactas la aplicación del teléfono funciona muy bien y de momento la batería funciona genial. No sé qué pasará en el futuro
My camper van is small, but my power needs are huge, so this 314Ah Mini is a blessing. It’s compact enough that I still have room for my actual gear, not just batteries. Delivery was fast—faster than I could finish my coffee. The Bluetooth app works great, which means my new favorite hobby is checking the battery status every time I blink. Solid build, high efficiency, and no headaches so far. Highly recommend if you want real power without losing your living space!
Good batteries, now will se what happening in time.
De perfecte boot accu voor schip van 10 meter.
Ook in de winter als de zonnecollectoren weinig leveren en koud weer is. Is de verwarming in de accu perfecte keuze. De 12V hetelucht verwarming doet het perfect op de accu.
Wat een uitvinding, super Watt cyclus.
Per ora do 4 stelle perché non l'ho ancora installata ne provata, ho solo collegata con Bluetooth e il tutto sembra funzionare benissimo ed è carica al 66%. penso comunque che sarà un buon prodotto.
Dalle recensioni che ho letto è visto, penso che sia uno dei migliori prodotti come qualità prezzo.
Posso solo dire per adesso che sia l'ordine che il trasporto (consegna veloce e perfetta come da foto) tutto ok 5 stelle.
una sola cosa ho visto che non ha, "il bilanciamento delle celle attivo ma passivo. Questa è una pecca, spero che le prossime avranno il bilanciamento attivo delle celle. Per adesso grazie.
Getting ready for the life in the wild. Everything working and looks great for now! App shows the state of the batteries and voltage for each battery cell.
Bin sehr zufrieden mit dem Produkt hält was es verspricht
Gerne wieder.
Great value for money. The size is perfect under the sofa in the van.
spokojen
The battery is excellent. The courier damaged my battery during delivery. I praise "Wattcycle" for the communication and fast delivery of the new battery.
so far so good!! Looking good en delivery was quickly
Die Batterien kamen in gutem Zustand und gut verpackt an. Lieferung inklusive kurzen und längeren Schrauben. Sehr hilfreich. Ich habe 4 davon als Hauptversorgung für die Wohnraumbatterien im Boot installiert. Sie ersetzen jeweils 4 AGM-Batterien mit 210Ah, die um die Hälfte größer und doppelt so schwer waren (je 120 Pfund) wie diese ~60 Pfund schweren 314Ah LiFePO4 Batterien. Dadurch verdreifachte sich meine Kapazität und ich sparte 240 Pfund Gewicht. Ich habe an jede Plus-Batterie 250A MRBF-Sicherungen sowie eine 350A Klasse T-Sicherung auf der gesamten DC Plus Seite angebracht. Zusätzlich installierte ich einen wasserdichten Victron 500A SmartShunt zur Überwachung von Lade-/Entladeständen. Für die Ladung ergänzte ich einen Victron Orion XS 50A-DC/DC-Ladegerät für die Lichtmaschine sowie ein 40A LiFePO4 AC/DC-Ladegerät mit ferngesteuertem Stecker. Bisher scheinen die Batterien wie angegeben zu funktionieren.
Buona batteria, 280 Ah smart mini.Per la su capacità ,gode di dimensioni super compatte. Si riesce a montare di fianco ( ho chiesto al suporto tehnico l'approvazione)
sotto il sedile del camper su base Ford Transit ,e credo anche Fiat Ducato.
The battery seems to be very good. Nice build quality, incredible capacity!
The BT is really disapointing. Just had an app-update. The app gives very little information. Just voltage, percentage of capacity, temperature. No information about the seperate cells. No possibility to change the settings of the BMS.
No worth the extra money spent on the Bluetooth module.
VERY IMPRESSED so far! I ordered 2 of the NEW 300 amp hour MINI lithium batteries, and they are working perfectly. I ordered them Friday, October 18th, 2024 and received them both on October 25, 2024 in perfect working order. I started off by testing 1 quickly then placing it in a freezer set to 26 degrees Fahrenheit to test the low temperature charging protection, left it in for about 12 hours and hooked to a charger and it would not allow a charge to pass! I allowed it to warm up slowing and then tested again and it then would allow charging again. Very happy to see this feature working! Being able to use my system in freezing conditions is very important to me and this helps to know my investment in these batteries will be protected!
The second battery I began charging up off my 1000 watts of solar panels and Victron charge controllers I have in/on my fully converted cargo trailer camper. I use it as an "off-grid baby camper" as I call it. We use the camper (I built in spring 2020) for family trips, camp outs, cross country road trips, and "deer camp" where we expect it to deliver all the comforts of home in a small package while going wherever we want. We depend on the solar and lithium batteries along with chargers and inverter to keep the food in the fridge cold, my family and pets cool in the air conditioning in the heat of summertime, electric heaters and diesel heaters keeping us warm in the winter. Along with being able to run a coffee maker in the morning or making microwave popcorn for watching a movie on the TV before bed.... all while being able to camp anywhere we want without the concern of pluging in at a campsite or having to listen to a noisy and stinky generator. So far the available power in these batteries compared to my previous lithium battery bank I can instantly tell these batteries will be a major upgrade to my system.
My previous system consisted of 465 amp hours of lithium-ion in 3 parallel batteries. Connected in my system with a 12v Giandel 2200/4000 watt inverter it powered all our needs but I noticed a slight delay in developing power on some higher demanding appliances. With my limited time with these new Wattcycle 300ah Mini's, I've so far hooked up some power tools in my garage and a microwave in my trailer and they all have preformed like they were plugged into a regular outlet in my house. That's with only 1 battery hooked up! I've already been so impressed I've purchased a third to make my system 900ah!
The compact size of these 300ah Mini's is remarkable! Each of them is about the size of my previous 160ah lithium-ion batteries. I am going to be able to double my total power in the same space. They do weigh more (about 57 pounds each) than my previous batteries, but that is to be expected with their higher density..... or whatever they've done to pack so much power into such a small battery.
