The lithium battery for your Buccaneer caravan.
From the Skyliner Cruiser to the flagship Starliner Aruba, every Buccaneer leaves the dealer with a lead-acid leisure battery that gives you roughly half its rated capacity and degrades a little with each season. A TITAN delivers close to 100% usable power in the same footprint, holds voltage flat for the motor mover and self-levelling, and handles months of winter storage without losing capacity.
Consett, County Durham: Britain's most prestigious twin-axle caravan
Buccaneer has been part of Erwin Hymer Group UK since 1998 and is manufactured in Consett, County Durham, alongside the Elddis and Xplore ranges. The brand sits at the top of the Erwin Hymer UK portfolio - it is the most premium touring caravan built by a UK-based manufacturer. For the 2026 model year the range divides into two tiers: the Skyliner, available in five layouts (Aruba, Barracuda, Bermuda, Commodore, and Cruiser), and the flagship Starliner, which offers three of those layouts (Aruba, Barracuda, and Cruiser) on an uprated 2,250kg chassis with a higher standard specification including air conditioning and a premium mattress.
Every Buccaneer is 8ft (2.45m) wide and built on a twin-axle AL-KO chassis, with automatic self-levelling and Alde wet central heating fitted as standard across the entire range. Alde runs on gas or, when connected to a 230V serviced pitch, on its electric heating element - which draws from the site supply rather than the leisure battery. Off-grid, the Alde burner runs on gas, but the pump and controls still draw from the 12V leisure battery throughout. The twin-axle build and generous MTPLM figures mean Buccaneer owners typically have substantially more payload headroom than a lightweight single-axle caravan, so fitting a larger battery bank rarely means sacrificing load allowance.
Like all towed caravans, a Buccaneer has no engine and no alternator. The leisure battery is the sole on-board 12V power source. That makes capacity and charging strategy more important than on a motorhome, and the shift from lead-acid to lithium is a more impactful upgrade here than on almost any other vehicle type. For a broader overview of switching to lithium in any caravan, the caravan battery guide covers the fundamentals.
Sizing a TITAN by Buccaneer model and usage
Every Buccaneer is twin-axle with generous payload, so you can fit a larger battery than you could on a lightweight single-axle van. Starting points by model tier and how you use the caravan.
| Model | How it gets used | Good fit |
|---|---|---|
| Skyliner Aruba, Barracuda, Bermuda, Commodore, CruiserStandard touring. Lights, fridge, Alde on gas, water pump, motor mover. Mostly serviced pitches. | Regular touring, serviced and unserviced pitches | 120Ah to 150Ah |
| Skyliner - any layoutExtended off-grid, inverter use, or prolonged stays on club certificated locations without electric. | Off-grid, inverter, extended stays away from hook-up | 180Ah to 230Ah |
| Starliner Aruba, Barracuda, CruiserFlagship tier. Higher standard specification, air conditioning, premium usage profile. Uprated 2,250kg chassis gives maximum payload for a large battery bank. | All usage - touring through to extended off-grid | 180Ah to 230Ah |
These are starting points, not fixed rules. The honest figure comes from your own loads - total them in the battery size calculator. Locker dimensions vary between model years and specification levels, so measure the space including terminal height before ordering. Twin-axle payload headroom on a Buccaneer is generous compared with lightweight single-axle caravans, which means a larger bank is often practical where it would not be on a smaller van.
Where the leisure battery lives in a Buccaneer caravan
Buccaneer caravans have an external battery locker, typically positioned at the front of the van. The exact location and the usable internal dimensions vary between model years and layouts - the best reference is your handbook, or measure the locker yourself before ordering a replacement battery. The key measurement to take is the height available above the terminal posts with the lid or retaining bar in place, not just the floor footprint, as terminal height is what most often catches owners out.
Because the external locker is exposed to British weather year-round, a sealed case matters. The TITAN case is rated to IP67, so it handles the damp, condensation, and temperature swings of an external front locker without issue. The RJ45 comms ports drop to IP32 while a cable is connected - keep any plugged port clear of standing water. The DIN-format footprint sits low and stable in the locker without rattling on the road, which matters on a twin-axle van covering longer distances at motorway speed.
If you are in any doubt about which battery fits your specific Buccaneer, check the external locker dimensions against the TITAN product dimensions listed on each product page, and contact our team if you need confirmation before ordering.
Charging your Buccaneer's lithium battery
A caravan has no engine, so there is no alternator. Charging comes from three sources:
- 230V mains hook-up via the onboard charger. This is the primary charging source on a serviced pitch. The onboard charger fills the leisure battery from the site's electric supply. Check your charger against the charger compatibility list to confirm it supports a lithium profile - most modern Buccaneer onboard chargers do, but it is worth verifying. A lithium battery charges considerably faster than the lead-acid it replaces, so the battery is typically full well before you need it to be.
- Roof solar through an MPPT controller. All 2026 Buccaneers come with roof solar provision as standard. Solar is the key charging source on club certificated locations and any pitch without electric. An MPPT controller extracts significantly more from the panels than a basic PWM unit - if the factory-fitted controller is PWM, upgrading it alongside the battery makes a meaningful difference. The solar sizing guide helps you match panel area to your real off-grid load.
- Trickle charge via the 12S or 13-pin towing plug. While the caravan is being towed, the tow car sends a small charge through the 12S or 13-pin electrical connection. This is a maintenance trickle - it keeps the fridge running and gently tops up the battery during the journey, but it is not a fast charge and is not a substitute for mains or solar. You arrive at the pitch with a slightly better state of charge than you left home with, which is a useful bonus rather than a significant charging event.
Motor mover and self-levelling. Buccaneer caravans are heavy, and motor movers draw a large surge current to get a loaded twin-axle van moving. A lead-acid battery that is even partially discharged can sag badly under this load, causing the mover to hesitate or cut out mid-manoeuvre. A TITAN holds its voltage flat right through the surge, so the mover responds as the manufacturer intended at any state of charge. Automatic self-levelling systems similarly draw peak current during levelling cycles - a healthy lithium voltage means they complete reliably without a low-voltage trip. The higher usable capacity also means you can manoeuvre and level several times on arrival without the battery falling to a level that affects performance.
Winter storage. Buccaneer caravans often sit unused from October to March. Lead-acid batteries self-discharge steadily and suffer permanent capacity loss if left discharged. A TITAN has a very low self-discharge rate and tolerates long storage without degradation. The built-in low-temperature heater in the custom BMS means the battery charges safely down to -30C - so if you connect solar or mains during winter storage, it accepts charge correctly regardless of ambient temperature. Every TITAN carries a lifetime, fully transferable warranty.
