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.

The short exploded video showcases our SMARTIQ SERIES ARCTICXTREME 150ah Lithium battery, with UL Listed, Grade-A, Prismatic Cells and self-heating technology that enables the battery to be charged in sub zero climates down to -20c enabling uninterrupted use.
Lithium Pro Energy use traceable QR coded, grade A, 'matched' EVE Lithium iron phosphate (lifepo4) cells in our batteries. Producing upwards 4000-8000cycles @ a 80% depth of discharge DOD. Compared to only 200-500 cycles of conventional 12v lead-acid deep cycle batteries.
A 12v lithium leisure battery can discharge 100% using all its stored energy. Whereas if you discharge conventional deep cycle lead acid batteries below 50% it causes permanent cell damage, resulting in reduced cycle capacity.
Our batteries have undergone rigorous sign-off tests to pass UKCA, CE, ROHS, RED and UN38.3. LithiumPro batteries have all been subject to Vibration tests, Shock tests, Short Circuit tests, Crushing, Thermal tests, even undergone testing at Altitude.
All lithium lifepo4 batteries can be recycled and do not contain any dangerous gases or sulphuric acid.
With a cell cycle capacity of upwards of 4000 -8000 cycles at a 80% depth of discharge means if used daily and cycled to 80% of its capacity it will provide up to 11-21 years of continuous power.
Unlike with lead acid, a lithium leisure battery does not require any maintenance.
Lithium is capable of of being fast charged at rates above 1C. Meaning a 100ah lithium battery can be charged in as little as 1hour if your charger is capable.
Our advanced proprietary 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. Weighing 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.
Lithiumpro Energy® batteries are designed with conventional (SAE) solid brass terminal posts. and with the traditional mounting rail at the base to safely secure the battery its tray.
When choosing a 12v lithium leisure battery for your application whether that be a motorhome, boat, caravan, or campervan you should carry out some market research on the brands available. There are many new lithium batteries flooding into the UK market and with enticingly cheap price tags. It is hard even for us, sometimes, to tell the difference of which are quality products and what are cheaply manufactured products with no certification. Many of the Chinese imports are a give away with their wacky names and branding.
Be wary of cheap Chinese imported batteries. Although they may seem appealing with their lower prices, they often suffer from poor quality components, manufacturing defects, quality issues and lack of official certification to be sold and used in the UK & EU Markets. These batteries rarely undergo any form of safety testing. Its important to note that if you suffer any malfunction with imported goods sold via amazon, ebay or the internet which results in a claim with your insurance company, you will find that you are not covered unless the product carries the appropriate certifications to be sold in the UK/EU.
Always Remember! cheaper batteries often come with no warranty or customer service backup. Here at LithiumPro we offer a dedicated customer care service and a comprehensive 5 year warranty support, leaving you to enjoy carefree adventures. Support British and prioritise reliable brands that meet all the UKCA, CE safety standards and offer UK customer support.
Many ‘off-the-shelf’ imported lithium batteries on the market lack the official certifications needed for legal sale and use in the UK and EU. In some countries, there are no strict manufacturing regulations, so companies often skip costly safety testing. At Lithium Pro, all our products undergo rigorous testing to meet the required certifications, including E-MARKING ECE R10, UKCA, CE, ROHS, RED and UN38.3
Motorhome and campervan manufacturers must follow strict safety and quality standards, only using E-marked products approved by governments or industry experts. In contrast, aftermarket van builders and converters are less regulated and can use uncertified components. However, they are responsible for ensuring the safety and quality of their work.
When purchasing batteries, always ask for certification to ensure you’re getting a product that meets the safety standards for your market.

Lower-cost lithium batteries often cut corners by using cheaper components or omit safety altogether in an effort to reduce costs.
For example, flimsy cotton straps may replace sturdy carry handles, and essential features like a base rail for securing the battery in vehicles may be missing. Safety features such as battery isolation, over current protection or even pre-charge protection are frequently not found on cheaper chinese imports.
Even externally, quality differences are visible—poorly applied labels, signs of rough assembly, with overspill when sealing lids with glue rather than precision fittings all indicate subpar construction.
At LithiumPro, we design all our batteries with screw-top cases, allowing easy access for servicing or part replacement if required. This approach enables us to fully honour our 5-year comprehensive warranty while ensuring superior quality, safety, and long-term reliability. Unlike many imported batteries, which are glued shut and cannot be repaired, our design promotes sustainability and peace of mind.

A Lithium Battery Management System (BMS) is essential for protecting and optimising lithium batteries, ensuring safety and longevity. Quality can vary significantly. The BMS controls the vital safety protocols built into the logic of the battery. It prevents dangerous scenarios that could lead to battery failure such as overcharging, over-discharging, over temperature, under temperature, over current protection, short circuit protection and incorrect polarity. Its also responsible for precision balancing of the individual cells that make up the battery pack. All these parameters are efficiently managed for optimal performance and reliability. A high-quality BMS safeguards against thermal runaway, electrical failures, and premature battery degradation, making it crucial for reliable performance in applications like Motorhomes, Campervans, Caravans, and Boats. Investing in a high performance battery with a quality BMS ensures safe operation, extended battery life, and peace of mind.


The image above of a poorly hand crafted BMS from a Lithium battery being imported for sale into the UK. It reveals a common theme found in cheap imported lithium batteries. The lack of build quality is concerning. Instead of utilising secure bolted connections to the BMS the manufacturer relies on poorly soldered joints, which are unsuitable for high-vibration environments such as motorhomes, campervans, and boats. This serverly compromises long-term reliability and safety of the product. The choice of cabling it protection and its limited cross-section suggest cost-cutting measures. The absence of thermal insulation or protection further indicates substandard construction. This BMS has very rudamenarty logic, this basic BMS logic provides minimal protection, lacking essential safeguards such as overcurrent protection and cold-temperature charging prevention. Many manufacturers permanently seal these batteries to conceal such shortcomings, which also prevents maintenance inspection or repairs.

Many importers are still selling the older style LiFePO4 cylindrical celled batteries. The vast majority are not traceable with not identification on them to acsertain the factories that produced them. Consequentially, you have no idea when the cells were manufactured or what Grade cells are being used inside the battery pack, let alone if they were ever certified to any form of safety standard post production.
All LithiumPro batteries use brand new cells produced by the top-tier manufacturers and are certified to stringent, UL standards, UL1973, UL1642 ensuring they meet both safety and performance criteria for use in vehicles as auxiliary power systems.
Cylindrical cells are much smaller in size and up to 80+ cells can be required to make a single 100AH battery. Four batches of 20 cells connected in series and then parallel to make up a 12.8v battery pack. This brings certain limitations in many aspects of design and battery longevity. Both monitoring and balancing 80 cells is a more complex task compared with more modern battery packs using only 4 Prismatic cells. Newer prismatic battery packs achieve superior battery performance for longer. The heat transfer of 80 cylindrical cells is far greater than just 4 prismatic cells. Also packaging of large numbers of cylindrical cells is not conducive to allow small compact designs either. Cylindrical cells are heavier and more bulkier in design. So make sure you understand what cells are in your batteries and if they have been UL certified for use in your application. Otherwise your insurers may refuse to cover you or payout in any claim.
When buying a lithium (LiFePO4) leisure battery in the UK — whether for your caravan, motorhome, boat, or off-grid solar setup — the quality of the individual cells inside is one of the most important factors. Not all lithium cells are the same, and using lower-grade ones can lead to shorter battery life, reduced performance, and even safety issues.

All LithiumPro batteries use modern prismatic LiFePO4 cells manufactured by EVE Energy, one of the world’s leading and most trusted cell producers.
Key advantages of these EVE cells:
Many budget batteries quietly use Grade B or recycled cells to hit a low price point. They might work fine for the first year or two, but you’ll notice the capacity dropping quickly, and the battery may fail long before the warranty suggests.
As of 2023, China dominates the global lithium production market, controlling approximately 80% of the supply. Lithium batteries worldwide utilise the same chemistry to achieve remarkable advancements in energy density and battery performance. However, it is crucial to recognise that the design, production, testing, and quality control processes can significantly vary among manufacturers.
LithiumPro batteries are designed to be used In high-vibration environments, such as motorhomes, campervans, and off-grid applications. The durability of connections between LiFePO4 cells is critical. Laser welding provides a permanent, robust bond that eliminates the risk of loosening over time, a common issue with bolted connections. Unlike bolts, which rely on mechanical pressure and can be affected by vibration, laser welding creates a seamless connection with no moving parts. Additionally, laser welding reduces resistance at the connection points, improving overall efficiency and performance, making it the ideal choice for demanding off-grid power systems.

Furthermore, as part of our quality control process, each battery undergoes a complete charge and discharge cycle before leaving our factory. This meticulous procedure ensures that every battery delivered to you is in optimal condition and ready to perform at its best.
The quality of critical components within the battery, such as the BMS (Battery Management System), is of paramount importance in ensuring the battery operates safely within defined parameters. These aspects of quality control play a vital role in determining the longevity, performance, and safety of our products.
At Lithiumpro Energy, we prioritise attention to detail during the design and manufacturing stages, we implement stringent quality control procedures throughout the production process ensuring all our components are high quality. We only use Grade A ‘traceable’ LiFePO4 cells. This commitment to excellence guarantees that there are no compromises when it comes to the quality and reliability of our batteries.
