Glen is very knowledgeable and very helpful. The replacement battery is a perfect drop in replacement in my Carthago motorhome. Highly recommendedPosted on Bill VincentTrustindex verifies that the original source of the review is Google. Every thing is good thanks to lithium pro energy battery still on max charge haven't be able to use it so far due to weather etc but what power I have use from battery has soon been topped up to max full charge by my 100watt solarPosted on ian bryanTrustindex verifies that the original source of the review is Google. After loads of research with regards to upgrading to Lithium, my biggest concern was having to completely change the charging system. I found the LithiumPro stand at the recent NEC show and I am so glad I did. Glen explained the difference between the cheaper batteries and also with the battery I was considering my original charging equipment should be able to cope. Overall Glen explained his product in the type of detail I needed to make my decision and bought a battery, even though it cost a lot more than I intended to spend. The quality and support is excellent and the installation was AGM out and Lithium in, no mods, etc. All seems to be working fine. I did have an issue with the App, but my fault. Glen was at the end of the phone and guided me through the connection process. I should have read the instructions. Overall really pleased with my purchase and the quality of the product is excellent. Its performing well and taken away the battery anxiety. Its also great to be able to speak to a person at the manufactuer if there is a problem. I have no hesitation in recommending LithiumPro productsPosted on AndyTrustindex verifies that the original source of the review is Google. Glen M*** at the Caravan & Camping Show was excellent this morning. Explaining the battery technology and my options to retrofit my van. 10/10 Performace, Knowledge and PolitenessPosted on Steve GambleTrustindex verifies that the original source of the review is Google. I upgraded my motorhome to a 105AH Ultravolt LithiumPro battery a couple of years ago. Great product and support. Initially I did have a question about Victron charge settings and recently an issue with me not understanding what happens with cold weather charging, both times the support, by WhatsApp, has been very fast and helpful. Full marks for both the kit and the after sales support.Posted on Daz The SailorTrustindex verifies that the original source of the review is Google. Had a great install by BlueFix and we agreed on a 24v system powered by this awesome 24v 280ah battery delivering top notch performance ( 600 amps in 12v) . I can see all the data through my cerbo touch screen giving live state of charge directly from the battery via a CANbus cable ! Want more data just open the blue tooth Lithium Pro app and every think their for the tech geek and peace of mind for the general user as you can monitor even down to individual cell level with a very handy battery health feature ! Luke at BlueFix working with Glen at Lithium Pro Energy have provided me with a great system and amazing customer service (5 year warrenty) both taking all the time needed to answer all my silly questions .. Using this battery with the inverter gives seemless 240 power which delivers all the power you need and never overstretching the battery which is constantly being looked after by the Battery Monitor System . Nearly two months in Im very happy and look forward to all the power I need this summer . If you want the best tech, power delivery, backed up by a great team then defiantly check out Lithium Pro Energy and they will look after you , thanks guys DazPosted on Oren KipnisTrustindex verifies that the original source of the review is Google. 3 months ago I purchased 2 Ultravolt 105 Ah batteries for my Volkswagen T3 camper, as direct replacement of 2 Lead acid 70 Ah units. The new batteries are lighter, function excellent and very stable on voltage. Prior to install the batteries, I needed some technical support, which I received from Glen on WhatsApp, although he was on annual leave. After being used to a state of charge of 40% after one night, The lowest state is 85%, enabling me to stay stationary for few days with the combination of a 200 watt solar panel. Understanding the technology, design and effort which has been invested in these batteries, I can highly recommend these to any body who considers a build, an upgrade or a replacement.Posted on Violet VynerTrustindex 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 gibsonTrustindex 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.

At LithiumPro, we design and engineer our own Battery Management Systems (BMS) rather than relying on generic, off-the-shelf solutions. This allows us to develop custom functionality tailored specifically to the needs of our markets.
One key innovation is our BMS is designed to accept a broader voltage range, making our batteries true drop-in replacement for lead-acid systems. As long as your existing lead-acid charger operates within 13.8V to 14.6V, our batteries will charge seamlessly—eliminating the need for costly charger upgrades.
This means you can upgrade to lithium power with minimal changes to your current setup, saving both time and money while enjoying the superior performance of LithiumPro batteries.
The SMARTCOMM SERIES sets the industry standard for safety features and technology. We were the first to incorporate Power Isolation on our products to aid safety during installation and maintenance.
Pre-Charge Protection is now built-In to our BMS keeping you and your system safe during connection with large inductive loads like inverters. LithiiumPro’s Active Balancing – Is built into the BMS as standard offering 1-5A precision balancing to keep your battery in optimal condition at all times.
Heated Cell Technology – Is fitted as standard on all SMARTCOMM SERIES batteries ensuring you can not only discharge in cold climates but also charge too.
CANBUS Connectivity – Again fitted as standard enables seamless ‘plug & play’ integration with Victron Ekrano and GX displays for full system control.
In our entire product range, we use only serviceable battery cases, making them fully repairable. Our design ensures easy accessibility, allowing for servicing and upgrades with the latest BMS technology. As technology evolves, you’ll stay up-to-date.
At Lithium Pro Energy, we prioritise the safety and quality of our batteries. That’s why all our Lithium Pro batteries have undergone thorough testing and certification, including CE, UKCA, ROHS, RED, and UN38.3. These stringent safety tests ensure that our batteries meet the highest industry standards. All SMARTCOMM SERIES batteries are E-marked TO ECE-R10 and have full Type-Approval for use by OEM’s.
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.


By integrating cutting-edge Bluetooth 5.0 technology into our battery range users can effortlessly connect their battery to a smartphone or tablet. Once connected, our user friendly interface offers real-time data monitoring of becomes possible. Gain valuable insights into your power usage and battery performance.
Download the free SMARTIQ BMS App, available for both IOS and Android platforms, and unlock a world of live data monitoring. Keep track of vital information such as voltage, wattage, temperature, amps, State of Charge (SOC) and an array of other features.
Our advanced Bluetooth technology establishes seamless communication with the Battery Management System (BMS) on board the battery. In case of exceeding usage parameters, the BMS acts as a safeguard, issuing warnings and sending notifications to your device. When necessary, the BMS automatically shuts down the battery to protect itself
No special charger is required. Any normal lead-acid battery charger designed to output a Constant Voltage Constant Current (CCCV) charge profile, which 95% of chargers do, then this is fine and safe for LithiumPro batteries. Many battery chargers will have pre-programmed settings for different battery chemistries. For Lithium batteries, select the ‘LiFePO4’ or ‘LI-ion’ profile. If your charger doesnt have a Lithium profile then select the closest charge profile between 14.2-14.6v.
Of course, should you wish to upgrade you old charger to a lithium based charger, we would recommend this, as it will charge faster and more efficiently, whilst offering more enhanced protection features during charging, thus preserving the life of you battery.
You can charge your Lithium battery using any or all of the three simple ways listed below:-
1. Harness your alternator’s surplus power to deliver a steady 14.4v charge voltage. Click here for DC-DC Chargers
2. Using a MPPT Solar Charge Controller, you can charge your leisure batteries at a regulated voltage using your solar panels ability to harness the suns energy. Click here for Solar Charge Controllers
3 Using a Mains hook-up charger, you can use a domestic 240v electricity supply to charge you leisure batteries via hook-up or shore power. Click here for Mains Chargers
CLICK HERE for the Ultimate guide to charging your Lithium Battery
IMPORTANT: When you first receive your battery, fully charge it until you get a ‘Cell Over Voltage’ (COV) notification. This indicates the battery is fully charged. Then, complete a full discharge until you get a ‘Cell Under Voltage’ (CUV) notification, showing the battery is fully discharged.This process allows your Battery Management System (BMS) to calibrate the State of Charge (SOC) in your app. The BMS will then learn to provide more accurate data, understanding both the 0% and 100% charge parameters.
It is recommended to charge your battery at ≤0.5C (0.5 times the battery’s rated capacity). For instance, if the battery has a capacity of 100Ah, the recommended charging current would be ≤50 amps. Please observe the maximum charging capacity listed on your battery.
Your Lithium Battery with a Constant Current Constant Voltage charger CCCV with a LiFePO4 charging profile.
Absorption should be set to 14.2-14.6v (14.4v Optimal)
Float should be set to 13.5-13.9v
De-sulfation/Equalisation should be switched off
Most Victron chargers already have a Lithium charging profile. However, should you wish to personalise your settings, please use the following;
Absorption voltage: 14.4V
Absorption time: Recommended setting is half an hour per 100ah of LiFePO4 battery (for example if you have 2x 150ah batteries select 90mins).
Float Voltage: 13.5V
Equalisation voltage: This must be disabled on all Lithium batteries as this can damage the battery with pulses of high voltages. This is designed for lead acid batteries to add with desulfation.
Temperature compensation: This should also be disabled on Lithium batteries.
Charged Voltage: This is where your battery is considered fully charged – Lithium batteries should be set to 14.4V for Victron equipment.
Low Temperature cut-off: All Lithium Pro Batteries have low temperature charging protection built into the BMS. SMARTCOMM SERIES batteries all have cell heating technology so this function needs to be disabled.
Discharge Floor: 0%
Tail Current: This is the minimum current at which the Smart Shunt considers charging or discharging finished. We recommend 4%.
Peukert Exponent: Not required – this is for Lead Acid batteries.

ULTRAVOLT (NO-HEATER)
Yes our ULTRAVOLT and ARCTICXTREME batteries are all ‘Drop-In’ Lead-Acid replacements. They are exactly the same size and shape as your old Lead-Acid batteries with the exact same terminal posts, so there is not need to change your electrical connections. They even have the base rail at the base to safely secure your battery in place. No need to look for inventive ways to strap Chinese replacement batteries down. Click here for ‘Drop-In’ replacement batteries.
Yes, all LithiumPro Energy batteries can be connected in Series or Parallel to increase the voltage or capacity respectively.
Our SMARTIQ BMS APP with also be able to display your battery system parameters as a whole in both Series or Parallel configurations.
WARNING: Never connect Lithium batteries of different brands, capacities, or ages together. All brands have unique Battery Management Systems (BMS), and mixing can cause imbalances in charging or discharging, potentially leading to overheating and premature failure. NOTE: Always fully charge each battery separately before connecting them in series or parallel. LithiumPro batteries can be configured as follows:
For series configuration, ensure each battery is charged to within 0.05V of each other to prevent imbalances.
For parallel configurations, use cables that are as short and identical in length as possible; batteries naturally equalise in voltage when connected this way.
LiFePO4 chemistry is the most stable and reliable of all lithium technologies. If cared for correctly and used according to the manufacturers guidelines you should still be using your Lithium Pro battery in 10+ years time. LithiumPro Energy only use traceable Grade-A Prismatic cell technology in all of their batteries which are capable of over 4000-8000 cycles at 80% depth of discharge. Meaning if used every day it will last between 11 -21 years, and still retain 80% of their rated capacity. We are so confident of all our batteries they are covered by our comprehensive 5 year manufacturers warranty.
Yes, you can safely discharge your Lithium Battery down to temperatures as low as -20ºc However, in general Lithium batteries cannot be charged in temperatures below zero unless they have cell heaters embedded within the battery. All LithiumPro Batteries have a safety feature built into the battery to prevent it charging below 0ºc if they do not have cell heating technology. If you are using one of our SMARTCOMM SERIES batteries they are come with cell heaters built-in as standard Click here to see our ARCTICXTREME V2 Battery designed for charging in colder climates.
Yes, our SMARTCOMM range have been exclusively designed to fit under the front seat of your motorhome or campervan. You can chose from the UK’s most powerful 175AH DIN H8 ArcticXtreme V2 battery, or the UK’s most powerful seat base battery ever, the advanced 280ah SEATBASE.
You can even fit 2 ArcticXtreme V2 in parallel for 350AH under the seat of Fiat Ducatos, Peugeot Boxers, Citroen Relays, Merc Sprinter, VW T7, VW Crafter, Transit Custom. Click here to see installation guide.
When connecting batteries together for communication via CANbus ports, use standard RJ45 cable to link them and terminate last battery with the RJ45 termination plug provided. See diagram here.
If you wish to connect your SMARTCOMM SERIES batteries to Victron GX, Cerbo or the Ekrano you will need to purchase a SMARTCOMM SERIES Cable.
LithiumPro SMARTCOMM SERIES batteries offer full Plug & Play integration with Victron via CANbus
CLICK HERE for more information how to connect your Victron equipment to LithiumPro batteries
The RJ45 termination adapter included with your battery is for when you are using CANbus to connect you batteries together in parallel. It enables the BMS in each battery to communicate with one another and to Victron equipment. If you are not using CANbus integration then this is not required, but do keep it safe for the possible future integration.
This switch is for optionally disabling and enabling the charging MOSFETS of the BMS remotely. This cable only works with V2 of the ARCTICXTREME.
When connected to RJ45 Port 1 and the switch is depressed this will disable all charging and discharging sources from the battery. You can use this when carrying out maintenance or just wish to stop all loads from consuming battery power. You will still be able to monitor the State of Charge , SOC, of your battery as the BMS will still be active.
If you wish to put your battery into long term storage 3-6 months we suggest using the BMS isolation switch at the top edge of the battery. This will also prevent all loads from draining the battery but will also shut the BMS down thus reducing power consumption to a minimum whilst in storage. Note: your app will not function in this state. The battery should be charged to 65-70% before isolating ready for storage.
With the newer version of the ARCTICXTREME & SEATBASE batteries we have included a longer Remote Power ON/OFF cable. This also switches of the power to the battery for putting it into hibernation. The power button is designed to be panel mounted for ease of access when isolating your battery for storage or maintenance.
The POWER button is for switching ON/OFF your battery.
When shipping your battery for the first time it will be shipped in ‘hibernation’ mode for safety. You will need to switch the battery on to start charging the battery.
The isolation button can be used to put your battery into long term storage 3-6 months. This will also prevent all loads from draining the battery but will also shut the BMS down thus reducing power consumption to a minimum whilst in storage. Note: your app will not function in this state. The battery should be charged to 65-70% before isolating and putting into storage.
Do not leave battery at 100% State of Charge in storage, this can reduce the lifespan of the battery.
