quoteLithium leisure batteries may be gaining traction in the motorhome world, but what about caravanners? We recently asked caravan owners whether they’re already using lithium, sticking with traditional lead-acid batteries, or thinking about making the switch.
After more than 320 votes in our community poll, the results show a mixed picture, with just over a quarter of voters (28%) telling us they use lithium leisure batteries already.
Almost a third said they were considering switching – but 40% of caravanners reported not using lithium leisure batteries.
So while lithium isn’t yet the majority choice for caravanners, a significant one in three are actively considering an upgrade, especially those who might be looking to spend nights off-grid on small sites.
Here’s what you told us…
Some of those who commented explained that switching to lithium isn’t always simple. Tony’s experience stood out: “I was about to buy lithium replacements, luckily I did a bit of research and my solar panels and converter are not compatible, so it’s not a straightforward swap.”
It’s an important reminder that even if a lithium leisure battery physically fits, you need to look at solar controllers, battery management systems, as well as possible wiring upgrades.
Some commenters highlighted that not all lithium technology is the same.
Steven pointed out a difference: “There is a safety difference between Lithium ion and LiFePO4, the latter being much safer… and the price is dropping to be on par with lead-acid.”
And engineer Alan shared a detailed explanation about the need for a proper battery management system (BMS): “The battery MUST have a BMS that monitors temperature and voltage at the individual cell level… Never fit any Li-Ion battery not certified for the use you intend.”
For caravanners who store their vans for long periods or remove their leisure batteries over winter, this guidance is invaluable.
Off-grid potential
Although many caravanners rely on electric hook-up, more owners are dipping their toes into off-grid caravan stays, and lithium’s benefits came through strongly in your comments.
Chris shared how much lighter and more efficient lithium is during off-grid breaks: “Performance has been excellent off grid… solar charges the battery so much quicker. It’s the future for off-grid.”
And Garry, although a full timer, offered inspiration for caravanners considering more self-sufficient touring: “We have been using KS Energy batteries for the last three years… It’s totally transformed our living…with plenty of solar on the roof we can go from March to October without using EHU at all. The batteries have performed flawlessly…and saved approx 35kg in weight over my last AGM’s.”
Worth it… or not?
Some caravanners remain cautious. Thomas commented: “On this occasion, I do not think the grass is greener…”
For caravanners who mostly use electric hook-up, several commenters agreed that lithium batteries might not yet justify the cost — but for those who enjoy the freedom of the quieter, more remote campsites or farmstays, it could be a game changer.
So, are caravanners ready for lithium leisure batteries?
Our poll shows that caravanners are more cautious than motorhomers, but interest is on the rise. Lithium offers advantages — lighter weight, faster charging, deeper discharge and better off-grid performance — but compatibility, installation cost and storage habits still influence the decision.
If you’ve upgraded your caravan’s leisure battery, or you’re thinking about switching, we’d love to hear more. Share your experiences in the comments below!

I had not thought about it until this article. It’s food for thought. But with 59% damp issue on my 4 year old Elddis Chatsworth. Also visible signs of water ingress, a 9 month wait for warranty repair, I think, I have bigger issues to worry about, at present!
We have a 135ah lithium battery with a 175watt solar panel changed the battery charger for a lithium compatable one,all good get off grid regularly no issues. Will be putting a bigger solar panel on the new caravan in march possibly a 300 watt ISH size as we intend to go away more in the autumn/winter
Made my mind up, it isn’t broken so I won’t change it
Bought a new caravan made by Hymer in 2023 I was told I needed a new battery management system as well as a lithium battery.
Hymer were unable to offer me an enhancement to facilitate this, had no plans to assist me and moreover my warranty may be prejudiced if I go ahead.
My caravan is now in for its 2nd service and my dealership advises me the manufacturer has not offered any assistance despite the fact that customer interest continues to rise both in caravan and motorhome customers. The danger is some are swoping to lithium without amending the managing systems.
Excellent information as always, thanks.
Very interesting and useful
