Caravan leisure batteries are becoming more popular as they offer many advantages over traditional lead-acid batteries. At Lithium Pro Energy we think we’ve designed the ideal Leisure Batteries for Caravans.
A Lithium battery is perfect for use in a Caravan as they do not release TOXIC or harmful GASES during charging or discharging. In summary, they extremely safe to have onboard your caravan with no need for any maintenance or gas and safety checks. Therefore, you can sleep easy with your battery onboard.
Inside, there are no chemicals. We use Premium Grade A ‘EVE’ Cells in our Ultravolt 105AH battery. As a result they have the ability to be cycled up to 4000 times @ 80% depth of discharge, unlike most other cheaper grade lithium cells its only 2000 cycles. In summary this means 10+ years of daily use. We have also made them serviceable by designing the battery top with secure fixings so we can service and maintain your battery if required. We do not glue our cases shut so you cannot repair them. Instead we use screws and a gasket to ensure it complies to highest to IP65 submergible waterproof standards.
Meet the perfect weigh saver for caravans – The 105AH ULTRAVOLT weighs in at just 10kgs thats over 60% lighter than your old deep cycle Lead-acid leisure battery. Our Lithium batteries offer 100% useable capacity – Unlike, your existing lead acid battery you can USE all the published amp hours in a single discharge without damaging your battery. Try this 5000 times before your battery will even start to feel the strain.
Recharge them in as little as just 1 hour and you’re ready to discharge them again. They will connect seamlessly to inverter and your solar system on board your caravan. Using our SMARTIQ advanced data monitoring software you are able to stream live data to ensure you are fully aware of your power status at anytime.
Lithium Iron Phosphate batteries (LiFePO4) can be used as a versatile alternative to 12v Lead-acid leisure batteries in most situations. The term ‘plug & play’ refers to being able to remove your old battery and replace with a new battery without having to change anything.
LithiumPro Energy offers a series of batteries that have global DIN standard size battery cases, that fit perfectly into your motorhome, caravan, campervan or boat. Our new generation of battery is the same size shell as your old lead-acid battery. Meaning they are identical in size and shape.
We use the same brass terminal posts for ease of installation we have retained the base rail at the bottom of a traditional Lead-Acid battery, so you can secure your new lithium battery in exactly the same place. There is no need to think of inventive way to secure your new battery
All LithiumPro batteries can be charged with the majority of Lead acid chargers as long as they charge between 13.8-14.6v. Many modern chargers now have a dedicated lithium LiFePO4 charging profile setting. It is best to select this setting as it will charge faster, more efficiently with extra built in safety parameters.
We have prepared a dedicated chapter to charging your lithium battery. An easy flow chart to guide you through whether you need to upgrade your chargers, how the chargers work and how to install them – follow the link below.
No, you do not need to change your existing solar charge controller to charge LithiumPro Batteries.
Modern Caravans are typically equipped with a solar charge controller to manage energy from the solar panels. However, if your Caravan has an older PWM (Pulse Width Modulation) charge controller, it may be worth considering an upgrade. PWM controllers are now somewhat outdated, as advancements in technology have introduced MPPT (Maximum Power Point Tracking) controllers, which are significantly more efficient.
MPPT charge controllers are more efficient than PWM controllers, by extracting more energy from the same solar panel. For example, with an MPPT controller, you could achieve up to 35% more charge from your existing solar panel setup.
If your Caravan is already equipped with an MPPT solar charge controller, simply adjust the charge profile to ‘LiFePO4.’ This setting ensures a safer and faster charge for your LithiumPro battery, optimising performance and longevity.
Yes you can charge a lithium battery from your alternator. This is a great source of energy and a powerful and quick way to recharge your battery.
Most caravans are setup to power the fridge and the leisure battery from the alternator whilst driving via the connection between the car and the caravan. The wiring from your vehicle to the caravan is very small and as such the current flowing to charge your leisure battery and the keep the fridge powered is small but it will charge nevertheless.
If you have a motor mover then this is your ideal battery. The ULTRAVOLT can discharge continuously at a huge 150A to withstand the large loads put upon the battery when moving a fully laden caravan up a slight gradient. This type of load on a Lead-acid battery will permanently damage the battery and will soon require replacing.
Motor movers usually only draw 40-80amps during normal use. However, if you need to manoeuvre your caravan up a slight gradient or you are moving a twin axle caravan or maybe a fully laden caravan then your mover will demand a much higher initial load from the battery in excess of 100A. Repeating this process will just kill your lead-acid battery and greatly reduce its life expectancy.
Most lithium batteries have a safety factor designed into the Battery Management System BMS that will shut down the battery should it exceed the designed at 75-100A of continuous load to protect itself. Whereas Lithium Pro batteries are designed to handle much larger loads due to their superior BMS architecture, that uses much higher quality components to handle the larger loads.
If you have a twin axle motor mover or require a larger discharge current then try our more powerful 175AH ARCTICXTREME V2 model this can discharge continuously at 200Amps
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 re-engineered BMS, designed to accept a broader voltage range, making our batteries a 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.
With our onboard Active Balancing Module – An advanced variable 1–5A active balancer maintains optimal balance among the Grade-A LiFePO4 cells by distributing voltage between cells during charging. Enhancing performance, extending lifespan, and ensures a perfectly balanced battery ever charge no matter what charger you use.

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’ profile or the closest charge profile between 14.2-14.6v.
Of course, should you wish to upgrade 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
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
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: The Drift batteries have low temperature charging protection built into the battery. You can leave this off.
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.
Yes our SMARTIQ Series 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.

Yes, all LithiumPro Energy batteries can be connected in Series or Parallel up to a maximum of 4 units. Our SMARTIQ BMS APP with also be able to display your battery system 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.
Lithium batteries are extremely reliable technology. If cared for and looked after according to the manufacturers guidelines you should still be using your 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, Lithium batteries cannot be charged in temperatures below zero unless they have heaters embedded within the battery.
