Lithium Batteries for Motorhomes
A lithium leisure battery that runs the whole van for a week off-grid.
TITAN 12V LiFePO4 batteries replace your motorhome's lead-acid leisure bank with up to 5x the runtime, half the weight and a 10x cycle life. Designed in the UK, end-pack QC in Cheltenham. Lifetime warranty, lifetime app monitoring, and the comms package to talk directly to your Victron, Sterling or NOCO charger.
A lithium battery the rest of the van trusts.
Motorhomes are a tough environment for a battery. Vibration, heat, cold, deep discharges, fast alternator charges, solar input, the inverter that spikes when the microwave kicks on - lithium has to handle all of it without nuisance-tripping. That's where our custom BMS earns its keep.
Every TITAN motorhome battery ships with a heater pad built in. Lithium can't take a charge below 0°C, so the BMS pre-warms the cells before letting any of the incoming current through to charge. The heater uses the incoming charge current first; if that's not enough to bring the cells up, the BMS draws up to 3.6A from the pack itself to finish the job. Either way it's fully automatic. That's why our packs work properly through a UK winter where most lithium leisure batteries simply refuse to take a charge.
The comms package is the second piece. CAN-bus to Victron Cerbo and the GX range, RS485 for compatible monitoring systems, Bluetooth to the TITAN App V2. The app recognises your appliances by their current signature - fridge, kettle, water pump, diesel heater - and flags anything drawing more than usual.
And there's the lifetime warranty - fully transferable, no registration, repair-first. The full text lives on the lifetime warranty page.
Sizing maths in 60 seconds.
The rough rule for a motorhome is to size your lithium bank to 2 days of expected daily Ah draw, plus enough headroom for the inverter spike on a kettle or microwave. Most owners land somewhere between 105Ah and 180Ah of TITAN. Heavy users with diesel heaters running all night, full inverter kitchens and frequent off-grid stints lean towards the 180Ah or 230Ah.
- Weekend warrior, hookup most nights: 80-105Ah is plenty
- Two weeks off-grid, fridge + lights + USB + occasional inverter: 120-150Ah
- Full-timer, induction hob, big inverter, diesel heater overnight: 180-230Ah, or twin 120Ah in parallel
- Long-term off-grid with solar: 230-460Ah, possibly with a B2B charger
The battery size calculator walks you through it. Tell it what's on board - kettle, fridge, diesel heater, water pump - and it gives you a number and a recommended TITAN model. Two minutes.
