EXCELLENT Based on 31 reviews Posted on Violet Vyner2025-10-09Trustindex verifies that the original source of the review is Google. Without question a 5 star product and amazing support! My story… had 2 agm batteries on my campervan van and wanted to upgrade. Did loads of research into lipo4 batteries. I then talked to a really helpful guy at Lithium pro. I asked thousand questions about inverter compatibility and my existing bms etc. . He was very patient and answered everything without any sales pitch. I ended up buying the arctic extreme 175amp v2 along with the victron mains charger. There is no denying it is an expensive battery, but with the good warranty and features and build quality inside the battery, I felt that this battery would last me pretty much for my lifetime! ( in my sixties) . The battery is now installed in my van, with me asking more rather moronic questions on the whatsapp support ( they reply quickly). The phone app is super cool and i can see everything you could want to see re battery management. As for the power, im trying to run the battery down to zero ( to calibrate the app thing… just need to do it once) and after 2 days with fridge on its STILL got 87 per cent left! Excellent battery, excellent support and imo worth the money.Posted on malcolm gibson2025-10-08Trustindex verifies that the original source of the review is Google. Had my Lithium Pro 105Ah battery now for just over 12 months, well, what a game changer is has been. Did not tend to send much time off grid before because of "battery anxiety" but that is now a thing of the past. I have the blue tooth capable one and the app that you get is just brilliant, lets you know exactly what the status is and more. Took me a while to decide to take the plunge but glad I did. Wish I had done it sooner. At one point before a three week trip looked like it was not charging on electric hook up and phoned their technical service. They were brilliant, turns out it was my van with the issue but they talked me through it and helped get me sorted. 5 star service for reliability and post sales help.Posted on dave gledhill2025-08-07Trustindex verifies that the original source of the review is Google. Purchased a 105ah battery from them for my motor home. It's a direct replacement for my existing lead acid battery. No need to change the terminal connections or change my existing charger. The app to check on my battery has a good interface and allows me to double check that I have not left anything on when I park my motorhome up for a couple of weeks. Glen at the office was super helpful when due to user error, I let my battery drain a bit too much. He diagnosed the problem in seconds. Thank you.Posted on Jackie Short2025-07-18Trustindex verifies that the original source of the review is Google. We have had our 175 lithium battery for our caravan for a year and it works well and nice not to worry about the battery draining like a lead battery. We worked out that it will pay for itself within another year not needing electric hook up. We are mainly off grid and battery is sufficient for our usage. The people at Lithium Pro are all helpful and knowledgeable and would recommend them.Posted on Glynn Rixom2025-07-15Trustindex verifies that the original source of the review is Google. Decided to bite the bulletin and go lithium and purchased a 105ah Ultravolt. I was a bit worried the cost would outweigh the benefits. I recently went away for 3.5 days totally off grid. I previously was very careful in my 12v usage when off grid and managed to eke out my AGM battery for 3 days. This time I didn’t bother being careful with my 12v usage. We had showers every day, kept lights on until late, used Sat Tv every night etc etc . Ended up with 56% battery indicating I could have survived off grid for 6 days. Overall very impressed and happy I took the plungePosted on Glen Mcleod2025-06-25Trustindex verifies that the original source of the review is Google. I bought a 280amp seat base battery from Lithium Pro about 6 weeks ago this is probably the best upgrade I have ever made. I have 200w solar and a b2b charger and since fitting it I have not had to plug into grid power at all yet. I have a compressor fridge that I can run 24/7 with no worries. As most of my camping is off grid this makes things so easy. Glen is very knowledgeable and gave me some good advice. The icing on the cake was I got a phone call from Glen yesterday checking everything was working as it should, how many other companies do that after they’ve got your money. I can’t recommend this company and it’s products enough 5 STAR product and 5 STAR service.Posted on Jon West2025-06-10Trustindex verifies that the original source of the review is Google. The Articxtreme is a perfect fit for UK caravans and more than powerful enough to move my 2.3 ton VanMaster. So much better than lead acid. The charger was also easy to install and is very fast at charging. Staff always answer the phone and are very helpful, troubleshooting step by step and finding practical solutions. So glad we found LithiumPro. Highly highly recommended. Thank you, JonPosted on T&P2025-05-27Trustindex verifies that the original source of the review is Google. We had a 280ah Underseat battery fitted from Lihium Pro Energy and we can’t say enough about their fast delivery but also their aftermarket service is fantastic. We not tech minded but Glen and the lads walked us through all the settings to make sure everything was OK not only with the battery but also all our charging and solar settings to make sure they are working to the optimum efficiency. Thanks again for a great product and a reasonable price and for such good service.Posted on gary stubbington2025-05-27Trustindex verifies that the original source of the review is Google. Didn’t believe how easy it was to upgrade to lithium batteries. With the information they gave me it really helped to install. You need a bit of knowledge but I made several phone calls just to make sure. I’ve have had it for several months now and really happy with it. Thank youPosted on Gareth Mckee2025-05-26Trustindex verifies that the original source of the review is Google. So I had a lot of back and forth chat with Glen. He is very knowledgeable and interesting guy if you're into batteries. So I left my review a good while to test the battery. I bought the 175AH arcticxtreme V2. This fits into a standard (low profile) caravan locker. I actually get 182AH from it. So it's more than rated. I upgraded my solar to victron 175w and mppt. Then I upgraded my BCA charger from apuljack to lithium profile. Quote expensive really. But we have a coachman xcel and did suffer with AGM not lasting at all. Using the battery app I can see our movers pull 100 amps at times. No idea how the wires don't melt actually. Then the leveling. No wonder AGM batteries are not so good. Since moving to this I have never been near flat. Even running a coolbox fridge and no hook up for 4 days. No problem. The solar with this battery smash it easily. I would always use these batteries. I don't think you can match the case size Vs power output. Really solid product even in winter.
Lithium iron phosphate (lifepo4) batteries can produce 5000cycles @ 90% depth of discharge. whilst still retaining up to 80% of their original capacity thereafter. compare this to 200-400 cycles of conventional 12v lead-acid deep cycle batteries.
A 12v lithium leisure battery can discharge 100% using all its stored energy. conventional deep cycle, lead acid batteries discharging below 50% causes permanent cell damage.
Our batteries have undergone rigorous sign-off tests to pass UN38.3 for transportation. They have been subject to Vibration tests, Shock tests, Short Circuit tests, Crushing, Thermal tests, even undergone Altitude training,
All lithium lifepo4 batteries can be recycled and do not contain any gases or sulphuric acid.
If you discharged a 12v lifepo4 battery to 50% every day for 365 days it would give you over 10 years of continuous power.
Unlike with lead acid, a lithium leisure battery does not need maintenance. no more topping up with distilled water
Our 12v lithium plus battery can be charged from flat to full in as little as 1 hours
Our advanced on-board Battery Management System (BMS) Safeguards the battery in case of exceeding usage parameters. When necessary, the BMS automatically shuts down the battery to protect itself.
At 9 kgs our COMPACT Lite battery is the lightest on the market. Weighs less than half the equivalent 12v lead acid, AGM or GEL battery.
Lithium leisure batteries exhibit a low self-discharge rate of less than 3% per month. This means that you can store them for extended periods without the need for frequent charging.
Unlike lead acid batteries, Lithium does not emit harmful TOXIC gases during charging or discharging. You can safely store them inside your vehicle without any health risks.
Our lithiumpro energy® batteries are designed with familiar conventional (sae) solid brass terminal posts. along with the traditional mounting rails at the base to safely secure the battery its tray.

Using the latest Bluetooth 5 technology on your IOS or Android device you can pair to a SMARTIQ SERIES battery for real time data monitoring.
Whether your system is connected in SERIES or PARALLEL with our APP you can now monitor all your battery data on a single screen
The BMS Battery Management System controls all battery parameters, logging and logs the faults when it has had to intervene for safety and help you use your battery more efficiently.
No more guessing - Get live data showing the % State of Charge SOC of your battery and how long till your battery will be to fully charged or completely discharged
