The lithium upgrade for your motorhome.
Most UK motorhomes leave the factory on a single lead-acid leisure battery that you can only half use and that hates being left over winter. A TITAN drops into the same locker, gives you the full rated capacity, and saves weight you can put back into your payload. It is the same DIN format your van already takes, whether you run a Bailey, a Swift, an Elddis or an Auto-Trail.
Why motorhome owners switch to lithium
A coachbuilt or A-class spends long spells parked, then gets used hard for a fortnight at a time. That pattern is exactly what wears a lead-acid battery out, because it sits part-charged and sulphates between trips. Lithium does not mind sitting, gives you close to 100% usable capacity, and recharges far faster when you do get going.
The other win is weight. Swapping a heavy lead-acid bank for a single TITAN frees up payload, which matters on the lightweight Ford-based vans like the Bailey Adamo where every kilo counts towards your MTPLM. You get more usable power and less weight at the same time, which is rare.
Every TITAN uses a custom BMS with a built-in heater so it charges safely down to -30C, carries a lifetime, transferable warranty, and is opened, retorqued and discharge-tested by hand at our end-pack QC bench in Cheltenham before it ships.
A starting point by motorhome
Layouts and battery lockers vary a lot between models and years, so treat this as a guide and measure your locker before you buy.
| Your motorhome | Typical setup | Popular fit |
|---|---|---|
| Bailey Adamo, AloraLightweight Ford-based, payload-sensitive | Weekend and touring use, save weight | 120Ah to 150Ah |
| Swift, BessacarrKon-tiki, Voyager, Edge and similar | Fridge, heating, water and devices | 150Ah to 180Ah |
| Elddis Autoquest, AccordoCompact and mid coachbuilt | Touring, occasional off-grid | 120Ah to 180Ah |
| Auto-Trail, AdriaLarger tourers, more onboard kit | Longer off-grid, inverter use | 180Ah to 230Ah |
| A-class and twin-batteryHymer, Carthago, Auto-Sleeper and similar | Full-time and high-draw setups | 230Ah+ or twin packs |
These are popular pairings, not a guaranteed fit. Locker size and shape differ by model, year and converter, so check the battery dimensions against your space, or send us a photo and a measurement and we will tell you honestly what works. To total your own daily use, run the battery size calculator.
A true drop-in replacement
UK motorhomes are built around a standard leisure battery box, usually a DIN Type 019 footprint. TITAN packs are made to that same format, so in most vans the upgrade is a genuine swap: out with the lead-acid, in with the TITAN, reconnect and go. There is no tray to rebuild and no relocating the battery.
Because one TITAN gives you the usable energy of two lead-acid batteries, a lot of owners downsize a twin lead-acid bank to a single lithium and reclaim both space and weight. If your van runs a charger or solar controller set for lead-acid, it is worth setting it to a lithium profile, and our charger compatibility list covers what works.
Charging on the road and on site
A motorhome charges from three places: the mains charger on hook-up, roof solar through an MPPT, and the engine while you drive. Lithium takes all three faster than lead-acid, so a sunny afternoon or a decent drive puts real capacity back rather than a trickle.
For charging from the engine, a DC-DC (battery-to-battery) charger is what we recommend, and we would fit a Victron Orion every time. A standard split-charge relay does work, and many motorhomes already have one, but it is not the most reliable way to charge lithium and some relays cause a backfeed that quietly skims around the top 15% off your usable capacity. Feeding straight off the alternator with no relay and no DC-DC is not something we recommend.
