LiFePO4 batteries for campervans: 100 Ah and 200 Ah compared
SpaziouSpaziou · Campervan power · 2026 comparison
More time off-grid.
Fewer worries.
A good LiFePO4 battery can change how you travel: fridge, lights, phones, water pump and remote work without constant dependence on a socket.
Start with your actual consumption
You do not need the biggest battery. You need the right one.
Before comparing brands, calculate how much energy you use each day and how you will replenish it. A 100 Ah battery can suit an efficient campervan perfectly; 200 Ah makes sense when consumption and charging justify the step up.
The quick answer
100 Ah for an efficient campervan. 200 Ah if your consumption and charging setup call for it.
At a nominal voltage of 12.8 V, 100 Ah is approximately 1,280 Wh and 200 Ah around 2,560 Wh. What matters is not just storage capacity, but also how much you use and can replenish each day through the alternator, solar or mains.
100 Ah, 200 Ah or more
Size your battery before choosing a brand.
The right capacity comes from three figures: Daily consumption in Wh, days without charging and usable reserve to retain. Then check whether your solar system, DC-DC alternator charging and mains charger can return that energy to the battery.
Convert daily consumption and desired autonomy into nominal Ah and Wh.

What to check before buying LiFePO4.
1. Convert Ah to Wh
To compare energy, multiply nominal voltage by amp-hours. At 12.8 V, a 100 Ah battery stores around 1,280 Wh nominal and a 200 Ah battery around 2,560 Wh.
2. Check the BMS
The BMS limits the current you can draw from the battery and provides protection. If you use an inverter, check the continuous current required rather than relying only on the inverter's advertised power.
3. Consider cold conditions
Charging LiFePO4 batteries at low temperatures requires protection. If you travel in winter, prioritise models that clearly specify a cold charging cut-off or self-heating system.
4. Measure the space
Two 100 Ah batteries can have very different dimensions. Measure length, width and height, allow room for terminals and wiring, and check how you will secure the battery.
5. Size the charging system
A large battery is of little use if it takes days to replenish consumption. Consider solar, DC-DC and mains charging together and think about how you actually travel.
6. Protect the installation
Fuses, cable sizes, isolators and connections must be sized for the actual current. If you lack experience with vehicle electrics, consult a professional.
Before confirming your basket
Check capacity, BMS, maximum current, cold protection, dimensions, weight, warranty and compatibility with your DC-DC charger, solar controller and inverter.
Your questions answered
Frequently asked questions
Is 100 Ah enough for a campervan?
It can be enough for an efficient campervan with a fridge, lights, pump and moderate electronics, especially with daily alternator or solar charging. Calculate consumption in Wh first.
When is upgrading to 200 Ah worthwhile?
When daily consumption is high, you want several days of reserve or frequently use a computer and inverter. Also make sure your charging system can replenish that energy.
Why does the BMS matter?
It is essential because it manages and protects the battery. Its maximum current also determines continuous output, which matters especially when using an inverter.
Do I need Bluetooth?
Not essential, but convenient for checking state of charge, current, temperature and other data on your phone, depending on each manufacturer's app.
Can I directly replace an AGM with a LiFePO4 battery?
Not always. Check the charger, alternator or DC-DC charger, solar controller, charging voltages, wiring and protection. A simple physical swap does not guarantee electrical compatibility.
What about cold temperatures?
LiFePO4 batteries can discharge in cold conditions within the manufacturer's limits, but charging at low temperatures needs particular care. Always check the specific protection of the battery you buy.
