Marine lithium batteries are becoming more popular for use in the Marine sector as they offer many advantages over traditional lead-acid batteries. At Lithium Pro Energy we think we’ve designed the ideal Leisure Batteries for Marine use.
LithiumPro batteries are ideal for use in Boats as they are IP67 rated waterproof fully submersible. They do not release TOXIC or harmful GASES during charging or discharging. In summary, they extremely safe to have onboard your vessel with no need for any maintenance, gas and safety checks. Therefore, you can sleep easy with your Marine Lithium battery onboard.
Lithium marine batteries power varying devices and electronic equipment onboard boats, including GPS systems, trolling motors, fish finders and more. LithiumPRO’s LiFePO4 deep-cycle battery is designed to be completely discharged and recharged up to 5000 times without damage to the battery.
At LithiumPRO we have designed our batteries specifically for use in the marine sector. In particular, we have made use of the familiar Automotive style battery box with base rails for safely securing them into your vessel. 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 harmful chemicals to spill out or give off harmful toxic fumes during charging and discharging. So very safe to have onboard your boat. LithiumPRO use Premium UL LISTED Grade A ‘EVE’ Prismatic Cells in our Ultravolt 105AH battery. They provide exceptional durability and can charged and discharged up to 5000 cycles. A capability not commonly found in less expensive lithium cells. In summary this means 10+ years of daily use.
Weighing in at just 10kgs the Ultravolt is over 60% lighter than your old deep cycle Lead-acid leisure battery. Lithium Pro batteries offer 100% useable capacity – Unlike, your existing Lead-Acid battery, here you can USE all 100% of the published amp hour rating in a single discharge without damaging or sulphating your battery. Try this 5000 times before your battery will even start to feel the strain.
Recharge them in as little as a 2 hours with a 50A charging device and you’re ready to discharge them again. They will connect seamlessly to an inverter and your existing solar system on board your vessel. Using our SMARTIQ advanced data monitoring software you can stream live data to ensure you are fully aware of your power status at any time.

Your best option is a LithiumPRO battery with high discharge currents. LithiumPRO offers 3 battery choices for you marine leisure battery see below:
The COMPACTLite battery has a 100A rated continuous discharge capacity which is suitable for most ‘weekend warriors’
The ULTRAVOLT comes with Bluetooth enabling users to 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.
The ULTRAVOLT can be discharge continuously at a huge rate of 150A to withstand the large loads put upon marine batteries when operating large inverters and industrial equipment. This type of load on a Lead-acid battery will permanently damage the cells and will soon require replacing.
If you require a larger discharge current than 150A try our ARCTICXTREME model this can discharge continuously at 200Amps
Lithium iron phosphate (lifepo4) batteries can produce 5000cycles @ 90% depth of discharge. whilst still retaining up to 80% of their original capacity thereafter. compare this to 200-400 cycles of conventional 12v lead-acid deep cycle batteries.
A 12v lithium leisure battery can discharge 100% using all its stored energy. conventional deep cycle, lead acid batteries discharging below 50% causes permanent cell damage.
Our batteries have undergone rigorous sign-off tests to pass UN38.3 for transportation. They have been subject to Vibration tests, Shock tests, Short Circuit tests, Crushing, Thermal tests, even undergone Altitude training,
All lithium lifepo4 batteries can be recycled and do not contain any gases or sulphuric acid.
If you discharged a 12v lifepo4 battery to 50% every day for 365 days it would give you over 10 years of continuous power.
Unlike with lead acid, a lithium leisure battery does not need maintenance. no more topping up with distilled water
Our 12v lithium plus battery can be charged from flat to full in as little as 1 hours
Our advanced 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. Weighs 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.
Our lithiumpro energy® batteries are designed with familiar conventional (sae) solid brass terminal posts. along with the traditional mounting rails at the base to safely secure the battery its tray.
Using the latest Bluetooth 5 technology on your IOS or Android device you can pair to a SMARTIQ SERIES battery for real time data monitoring.
Whether your system is connected in SERIES or PARALLEL with our APP you can now monitor all your battery data on a single screen
The BMS Battery Management System controls all battery parameters, logging and logs the faults when it has had to intervene for safety and help you use your battery more efficiently.
No more guessing - Get live data showing the % State of Charge SOC of your battery and how long till your battery will be to fully charged or completely discharged
With the familiar SAE Solid Brass terminal Posts on our Lithium leisure batteries there is no need for you to change your existing leads or connecting terminals. Just remove your old Lead Acid battery and replace with a Lithium Pro smart Series.
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 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.
