Detailed Reviews
1. EcoFlow DELTA 2 — £899
Rating: 4.8/5
The EcoFlow DELTA 2 has become the go-to power station for UK van lifers. With a 1024Wh capacity, you can run a 12V fridge for up to 24 hours, charge your phones and laptops multiple times, and even power a small heater on low. In my testing on a three-week Scottish Highlands trip, it handled everything from a fridge to a portable projector without needing a recharge.
2. Bluetti AC200MAX — £1,599
Rating: 4.7/5
The Bluetti AC200MAX offers 2048Wh of capacity in a rugged, all-aluminium housing. It is heavier than the EcoFlow but offers significantly more power for appliances like kettles and microwaves. Perfect for basecamp setups where you are not moving the unit daily. The AC outlet delivers 2200W — enough for most UK standard appliances.
3. Vicatam 12V Lithium Battery 100Ah — £299.99
Rating: 4.5/5
For pure 12V battery value, the Vicatam 100Ah is hard to beat at under £300. BMS-protected, with Bluetooth connectivity to monitor charge levels from your phone. In a standard Transit Custom, this fits neatly under the bench seating and will power a fridge, LED lights, and phone charging for 3-4 days before needing a recharge.
4. BLUETTI 12V Lithium Battery 100Ah — £349.95
Rating: 4.6/5
BLUETTI's dedicated 12V lithium battery is a solid choice for those who want a proven brand. The 100Ah capacity delivers consistent voltage and the built-in BMS protects against overcharging. Excellent for UK winters where temperature fluctuation can kill lead-acid batteries.
5. Victron Energy Lithium 100Ah — £649
Rating: 4.7/5
Victron is the gold standard in marine and van electrical systems. Their 100Ah lithium battery is pricier but comes with a 5-year warranty and near-perfect reliability. The VictronConnect app gives you real-time monitoring of voltage, current, and temperature.
Buying Guide: What to Look For
Key factors when choosing a campervan battery:
-
Capacity (Ah) — The 100Ah capacity is the sweet spot for most UK campervans. It provides enough power for a fridge (30Ah/day), LED lighting (10Ah/day), and phone charging (5Ah/day) for 3-4 days.
-
Lithium vs AGM — Lithium batteries are 2-3x more expensive upfront but last 2,000+ cycles vs 500 for AGM. For long-term UK van life, lithium pays for itself within 2 years.
-
BMS (Battery Management System) — Always choose a battery with an integrated BMS. It protects against overcharging, overheating and deep discharge — all common killers of van batteries in the UK.
-
Weight — A 100Ah lithium battery weighs about 10kg vs 30kg for AGM. In a small van conversion, every kilogram matters for fuel economy.
-
Price per cycle — The Vicatam at £299.99 delivers the best price-per-cycle ratio, making it ideal for budget UK van builds.
FAQ
How long will a 100Ah lithium battery last in a campervan?
A 100Ah lithium battery will power a 12V fridge (30Ah/day), LED lighting (10Ah/day), and phone charging (5Ah/day) for approximately 4-5 days before needing a recharge. This assumes you do not have a strongbox, if you are running a 12V microwave or kettle, cut that to 1-2 days.
Do I need an inverter to run 240V appliances from a campervan battery?
Yes, an inverter converts 12V DC to 240V AC, allowing you to run standard UK appliances. A 300W pure sine wave inverter handles laptops and kettles. For running a fridge and kettle simultaneously, you will need 1000W+. Factor in around 10% energy loss during conversion.
Conclusion
The best campervan battery for UK use depends on your budget and power needs. For most UK van lifers, the Vicatam 12V Lithium Battery at £299.99 offers the best value-to-performance ratio. If budget allows, the Victron Energy Lithium 100Ah at £649 is the premium choice with a 5-year warranty.
