The 12V 280Ah Seatbase Lithium Battery delivers an impressive 250A/3200W continuous discharge capacity, making it the perfect choice for powering air fryers and induction hobs effortlessly when paired with a suitable inverter. Plus, it provides ample reserve capacity to support other off-grid adventures.

Engineered with cutting-edge automotive cell technology, this battery boasts an outstanding cycle life of over 8,000 cycles, far surpassing the 3,000 cycles offered by other seatbase manufacturers. Designed for performance and longevity, it’s the ultimate solution for those seeking seamless ‘plug & play’ integration with Victron, innovation, reliability, and high performance off-grid energy.

This state-of-the-art lithium battery is part of a range developed by Lithium Pro Energy called SMARTCOMM SERIES offering advanced market-leading capacity, power and safety features embedded within the battery as standard;

  • TYPE APPROVED: Certified to ECE R10, a requirement for road-legal installation. Mandatory in the UK for OEM and retrofit installers in motorhomes, campervans and commercial vehicles.
  • VICTRON PLUG & PLAY: All SMARTCOMM SERIES batteries can be seamlessly integrated with Victron CERBO & EKRANO devices for full control. Remember to add your SCS CABLE.
  • EVE GRADE A CELLS: All LithiumPro batteries use only traceable UL-listed cells that are matched for voltage, internal resistance, and capacity before assembly.
  • PRE-CHARGE PROTECTION: An essential safety feature that prevents dangerous surging currents, sparking, and arcing when connecting the battery to high-load devices like large inverters, thereby protecting the BMS and connected electronic devices from irreparable damage.
  • ADVANCED 250A BMS: This powerful Battery Management System enables you to continuously discharge at 250A, allowing you to run most household appliances up to 3200W when combined with an inverter.
  • ACTIVE BALANCING: Integrated into LithiumPro’s proprietary BMS, the advanced variable 1–5A active balancer maintains optimal balance among the Grade-A LiFePO4 cells by distributing voltage between cells during the charging cycle. This advanced technology provides enhanced battery performance, extends lifecycle, and improves safety, as a well-balanced battery performs better and operates more reliably, no matter what charger you use.
  • BATTERY ISOLATION: This advanced safety and protection feature allows you to safely isolate your battery during maintenance and completely disconnect it from its loads for winterisation with the press of a button. No more fumbling around trying to disconnect large battery cables.
  • SMARTIQ BMS: LithiumPro’s industry-leading SMARTIQ Battery Monitoring System offers a user-friendly interface for real-time monitoring of your system’s performance. Whether you have batteries configured in parallel or series, the app provides an overview of system status, battery health, and state-of-charge (SOC) remotely via your smart device using advanced wireless technology.
  • AUTO HIBERNATION: Designed to save battery life and enhance performance. The BMS automatically activates hibernation mode and puts the battery to sleep, reducing its power consumption when it detects inactivity for 24 hours.
  • HEATED CELL TECHNOLOGY: Standard in all SMARTCOMM Series batteries, enabling safe charging at sub-zero temperatures to ensure continued operation in all climates.
  • CANBUS/RS485 CONNECTIVITY: Available on all SMARTCOMM Series batteries, this industry-leading connectivity enables seamless ‘PLUG & PLAY’ communication between multiple batteries, a wide array of head units and multi-functional displays and switching units like Victron GX, Ekrano, or marine NMEA-compliant devices such as GARMIN, CZONE, SIMRAD, and RAYMARINE to display vital battery parameters.

12v 280ah Seatbase lithium battery

One of the unique features of the SMARTCOMM SERIES is the latest onboard safety mechanism, which protects the battery and upstream connected electronics from dangerous arcs and sparks caused by powerful inrush currents when connecting to high-powered inverters. This 280Ah Seatbase battery, equipped with an advanced proprietary 250A BMS, which has the capability to run any household appliance up to 3200W when connected to a capable inverter, allowing you operate a ‘GASLESS’ system with plenty of spare capacity.

The SMARTCOMM SERIES from LithiumPro offers seamless Plug & Play integration via CANBus, allowing these batteries to communicate effortlessly with inverters, chargers, VictronGX, Ekrano, and any NMEA2000 compliant head unit, including CZONE, SIMRAD, and RAYMARINE. This enables the sharing of live system data for optimal performance and enhanced monitoring capabilities.

This battery is a genuine ‘PLUG & PLAY’ direct replacement for your lead-acid battery. If your motorhome or caravan has a lead-acid (CCCV) Constant Current Constant Voltage based charger that charges between 14.2v -14.6v you can install this battery and it will charge just fine, without the need to fit any other components. It will fit in exactly the same place as your old 95-110ah Lead acid battery and will charge using your existing CCCV charger.

Of course, should you wish to upgrade to a more powerful, dedicated lithium charger with a LiFePO4 profile, it will charge much faster and more efficiently, but it is NOT a requirement with our batteries. See here for dedicated lithium chargers.

This state-of-the-art lithium battery is part of a new range from Lithium Pro Energy called SMARTCOMM SERIES offering market-leading features embedded within the battery as standard.

One of the many unique features of the SMARTCOMM SERIES is the latest onboard safety mechanism, which protects the battery and connected electronics from dangerous arcs and sparks caused by powerful inrush currents when connecting to high-powered inverters.

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.

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 you

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.

Purchased a battery from lithium pro 6 months ago and was the best investment for my motorhome. Even with the 105ah it gives plenty of power and paired up with a 2000w inverter it turned the van into a hassle free wild camping van.The customer service again was by fair the best, glen at lithium pro has always been a message away if needed.I am that happy with the product I have just recently bought a 280 seat base for my van to help with more extreme wild camping in cold temps. I have looked at other manufacturers including the big names you see and I can say there nothin compared to the quality lithium pro provides
Response from the owner 08:33 27 May 25

Had 105 lithium system fitted to my new bailey adamo 75-4i. System brilliant but bailey need to pull there finger out so it can be monitored on the moho panel. Thankfully there is a very impressive app that tells you all you need, including incoming voltage be it solar panel or mains hook up as well as draw off. After care is excellent slight issue sorted in minutes. Think I purchased the right system

This battery has changed my camping experience. I invested at the beginning of last spring. I wish I took the plunge years ago. I don’t have to think about whether I have enough juice so keep my fridge and lights going anymore. I can charge my gadgets, loads of lights on, fridge on with ice compartment. No more hooking up, I get more choice where I pitch up too. The app is brilliant. In the beginning I had a few questions , I just WhatsApp lithium pro and they text back instantly, even at weekends. The service if excellent. I’ve booked on more green camping sites now. I’m so thrilled with the over all experience and service. Well worth the money. Many thanks lithium pro

Hi Amanda,Thank you so much for taking the time to leave us a nice review. It really helps us produce better products and improve our service. Also potential customers when reading real-life reviews of users provides insight into the benefits of using lithium.It would be great if you could you let us know what vehicle and if possible your setup ie. battery and the charger you have on board. This will help others to know it will work with their system too.Kind regardsJames

Excellent costumer service, very responsive to any questions on WhatsApp, even at weekends. Super important to me, as I installed over the weekend before a big trip, all season, in Winter! Unsolicited follow ups to how I was doing 3 weeks later also, Which was very nice!The 460ah Enduravolt battery has performed flawlessly so far, in winter ski resort conditions. It has integrated very well and charges fast with Victron solar, AC/DC and DC/DC chargers. Also, has the required protections to change off any charger I'm informed.

I couldn’t be more happy with my Lithium Pro leisure battery (175AH Arctic Xtreme). The battery is of the highest quality and I love the App which allows me to monitor the performance of my battery via my mobile phone. We are now able to be off grid in our camper van for extended periods.
Response from the owner 10:34 15 Dec 24
Hi Glynn,Thanks for the review. Keep an eye out we are releasing an updated version of the APP in the coming weeks.How much extra time have you been able to achieve off-grid since upgrading to LithiumPro ?

I have been thinking about upgrading to Lithium for a while. I came upon Lithium Pro Energy, and they were able to supply low profile batteries, which fitted into my existing underfloor battery box. Most batteries are too high, but these were exactly the same measurements as my old AGM’s, so just dropped straight in.When I placed the order for 3 x 175Ah batteries I knew it would be a month before they arrived in the country. Unfortunately this delay got longer, and rather than lose the sale, Glen from LPro decided to airfreight them in from China, at his expense, so great service.The batteries are now in and great quality, and actually over performing, and producing over 180Ah per battery. I am able to run my high current things, kettle, air frier hair drier etc without issue.In my opinion a very good product, from a good company, with excellent after sales service if you need to speak to someone.

We changed to Lithium battery as we needed the battery to last longer which it definitely does. Friendly and helpful I would recommend Lithium Pro Energy to anyone !

When I was in the market to change my battery, Lithium was the way to go. I had questions and concerns about the change and had great conversations about quality and fitting of a new battery via Whatsapp with someone from Lithium Pro Energy. They researched my charge unit for me and found it was able to charge their product without the extra cost of a charger. Explained why they are more expensive than others. Quality is one aspect. I have been running the Battery for 3 months now and it great to be able to see whats happening with it via the Bluetooth App. I would highly recommend this company.

I replaced three 210amp leisure batteries with two 150amp Lithium from Lithium Pro.Initially I was told to fully charge them and then fully discharge them.The charging was fine, took a bit longer than I planned but we got there eventually. I then needed to separately discharge them.This was harder than I thought. The batteries are on a narrow boat that is stuck in Wigan because one of the locks is broken, ideal I thought, I connected one battery, turned on the fridge/freezer, 32" TV, radio, and lights. I then went home planning to go back in a couple of days and connect the second battery.I returned two days later, the battery had dropped from 13.6v to 13.1v extraordinary, it took a further three days to flatten it, and then the same with the other one.These batteries are brilliant.The only limitation for me is the fact that they are in the engine room, basically a steel box and so the Bluetooth signal is struggling.These batteries are not the cheapest on the market, but in my opinion, worth every penny.

Started using Lithium Pro Energy from meeting them at the Nec in February 2024, now installing their 150ah batteries in all our builds. Their customer service is second to none, next day delivery, the app that works with the battery gives you great information on what’s happening in your camper giving you exactly how much power your using, Glens Knowledge to any of your questions is just what you want at the end of the phone or WhatsApp if you need it. Sherwood Campers highly recommend this company
