First Time Hearing About Lithium?
New to Lithium? Start Here.
No technical knowledge needed. Here's what a lithium upgrade is, in plain English.
A bigger, smarter leisure battery
Your leisure battery is what powers everything when you're not plugged in. Lithium (LiFePO4) is simply the modern version — lighter, safer and far more powerful than the old lead-acid type.
Way more off-grid power
A lithium battery gives you roughly double the usable power of the same-sized lead-acid battery. That means more nights off-grid, faster charging, and appliances that don't suddenly cut out.
Tried, tested & warrantied
LiFePO4 is the safest lithium chemistry — no fire risk in normal use, no maintenance, and the cells we fit are warrantied by the manufacturer plus our own 12-month workmanship guarantee.
Still not sure where you fit? Don't worry — tell us what you run in your van (fridge, lights, heating, TV, phones…) and how long you camp off-grid, and we'll recommend the perfect size. Get your free quote →
Why Upgrade to Lithium?
Leave Lead-Acid Behind
LiFePO4 lithium batteries are safer, lighter, longer-lasting, and deliver far more usable power than lead-acid alternatives.
Any Size Camper
From compact seat base systems to full-scale motorhome builds — a lithium system to suit your needs and budget.
Upgrade Pre-Existing System
Already have a lead-acid setup? We swap it out for lithium and give you more power, more freedom.
Lighter. Smarter. Stronger.
Lithium delivers more usable power in less space and weight — improving payload and performance.
Safer & Longer Lasting
Premium LiFePO4 cells — the safest lithium chemistry. 3,000+ cycles vs 300 for lead-acid.
More Power, More Freedom
Run appliances longer and go off-grid with confidence. Never cut a trip short due to flat batteries again.
Faster Charging
Lithium accepts charge much faster than lead-acid — from your alternator, solar or mains hookup.
The Difference
Lithium LiFePO4 vs. Lead-Acid
Why upgrading from lead-acid to lithium is the single biggest electrical improvement you can make
Lithium LiFePO4
More Power, Less Weight, Longer Life
80–100% Usable Capacity
Use nearly the full rated Ah — effectively double the usable power of a lead-acid bank
3,000+ Charge Cycles
10× the lifespan of a typical lead-acid leisure battery
Lightweight & Compact
Up to 70% lighter for the same capacity — frees up payload
Faster Charging
Accepts high charge currents from alternator, solar and hookup — less time plugged in
Built-in BMS Protection
Battery management system protects against over-charge, over-discharge and temperature
Consistent Voltage
Steady 12.8V output right down to empty — appliances run at full power, no sagging
Lead-Acid (AGM/Gel)
Old Tech, Wasted Power, Short Life
50% Max Usable Capacity
Half your rated Ah is wasted — discharge deeper and you damage the battery
~300 Charge Cycles
Lasts a fraction of the time before needing replacement, at higher lifetime cost
Heavy & Bulky
Significant weight eating into payload, especially with multiple batteries
Slow Charging
Tapered, stubborn top-up means hours plugged in to reach full
No Built-in Protection
Relies entirely on external equipment — easy to damage through over-discharge
Voltage Sags Under Load
Output drops as capacity falls — appliances lose power as the battery drains
Lead-acid may look cheaper upfront — but replacing it 3–4× times a lithium bank's lifetime costs far more in the long run.

Lithium Battery Upgrades for Motorhomes, Caravans & Campervans
Upgrading from lead-acid to lithium LiFePO4 batteries is the single biggest improvement most motorhome, caravan and campervan owners can make to their electrical system. A lithium battery delivers up to 80–100% of its rated capacity as usable power — compared to just 50% for lead-acid — meaning you effectively double your usable energy storage overnight.
At ALP Vans, we install lithium battery upgrades across the UK from our Gloucestershire base. We're brand-neutral and use premium LiFePO4 cells including Fogstar Drift seat base batteries and larger 100–280Ah units, paired with Victron Energy chargers and monitoring equipment to give you a complete, professionally integrated system.
Whether you have a compact VW campervan, a mid-size panel van conversion, a large motorhome with complex power needs, or a two-berth tourer caravan — we design, supply and install a lithium system tailored to your vehicle and usage. Our mobile installation service means we come to your home, storage facility or touring site. No need to tow or drive to a workshop.
Every lithium installation includes professional fusing, appropriate cabling, a battery-to-battery (B2B/DC-DC) charger for charging from the alternator, and — where applicable — integration with existing solar panels or mains hookup chargers.
