So why chose a Lithium Leisure battery for your Campervan battery...?

Deep cycle lithium leisure batteries are becoming more popular for use in Campervans as they offer many advantages over traditional lead-acid batteries. At Lithium Pro Energy we think we’ve designed the ideal Leisure Batteries for Campervans.

A Lithium battery is perfect for use in a Campervan as they do not release TOXIC or harmful GASES during charging or discharging. In summary, they extremely safe to have onboard your Boat with no need for any maintenance or gas and safety checks.  Therefore, you can sleep easy with your battery onboard.


At Lithiumpro we have designed our batteries specifically for use in Motorhomes, Campervans, Caravans and Boats. In particular, we have made use of the familiar Automotive style battery box with base rails for safely securing them into your vehicle. Additionally, we continue to use the high quality Brass terminal posts for the battery terminal connections. However, thats where the similarities end…
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 5000 times, unlike most other cheaper grade lithium cells. In summary this means 10+ years of daily use. We have also made them serviceable by redesigning the battery top with secure fixings in an effort to future proof your investment. We do not glue our cases shut but use a gasket to ensure it complies highest to IP67 submergible waterproof standards.


Weighing 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 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 2 hours and you’re ready to discharge them again. They will connect seamlessly to inverter and  your solar system on board your campervan. 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.

By integrating cutting-edge Bluetooth 5.0 technology into our SMARTIQ SERIES batteries users can effortlessly connect their battery to a smartphone or tablet. Once connected, real-time data monitoring of becomes possible. Gain valuable insights into your battery performance. Creating the ability to optimise your usage and the batteries long-term health.


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 CCCV Constant Current Constant Voltage battery charger that charges between 14.2v-14.6v will charge and balance a Lithium Pro battery fine.  However, should you wish to upgrade your charging system with a dedicated Lithium charger we would recommend this as it will charge faster, more efficiently and has more modern safety factors built in, but it is not essential to charge LithiumPro batteries.  Many battery chargers will have settings for various battery chemistries. For Lithium batteries, select the LiFePO4 profile or the closest to 14.2-14.6v normal AGM.

You can charger your Lithium Battery in 3 basic ways:-
1. Using a DC-DC Battery charger will use your alternator’s surplus power to generate a regulated 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 utilising 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 you should charge it fully until you get a Cell Over Voltage COV notification and then complete a full discharge until you get a Cell Under Voltage notification. This way your BMS will be able to calibrate your State of Charge SOC correctly, now understanding the parameters for both 0% and 100% state of charge.

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

Desulfation/Equalisation must be turn 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 voltageThis 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.
