LITHIUM BATTERIES FOR MOTORHOMES

Lithium batteries for Motorhomes are becoming the most popular upgrade, as they offer many advantages over traditional lead-acid batteries. At LithiumPro we offer the perfect drop-in replacement with the least hassle. LithiumPro batteries are will fit and are compatible with all brands of motorhome. Adria, Autocruise, Autotrail, Autosleeper, Benimar, Burster, Cathargo, Concorde, Chausson, Coachman, Elddis, Frankia, Hymer, Pilote, Rapido, Swift etc.

Our low-profile lithium battery is perfect for use in a Motorhomes as it will fit in exactly the same space as you existing Lead-Acid battery. It is identical in size.  Whether under the seat or in a battery box. The ARCTICXTREME is the ideal drop-in-replacement. We use Solid Brass terminal posts so you dont have to change any cables or connectors.

In most cases you can continue to use your existing chargers with LithiumPro batteries. 95% of existing chargers in todays motorhomes are compatible with LithiumPro batteries from Sargent, Schaudt, CBE, Dometic, Voltronic, Nordelectronica. If you have a Bailey, Coachman or Elddis that uses a BCA mains charger, these are not true chargers. They are only trickle chargers that prevent your battery from over discharging.  They only out put 13.8v, and will only charge a lithium battery to approximately 70%.  So you will need to upgrade to a lithium compatible charger that outputs between 14.2-14.6v.  Call or email for instructions of how to replace your existing BCA charger.

When upgrading your old lead acid battery to a LithiumPro battery – you do not have to start changing all your electrics to get it to work. Just drop in the hassle-free replacement and stay off-grid for longer. READ MORE ABOUT CHARGING HERE….

HOW TO REDUCE THE WEIGHT OF MY MOTORHOME?

Weighing in at less than 60% of your old deep cycle Lead-acid leisure battery, LithiumPro batteries represent a huge weight saving. a standard 100AH AGM battery weighs from 20-28kgs vs just 10kgs for the ULTRAVOLT Lithium battery.   

Two of our ARCTICXTREME batteries providing a whopping 350ah are designed to fit perfectly under the seat of you Fiat Ducato, Peugeot Boxer and Citroen Relay. See diagram.  Recharge them in as little as just 2 hours with a Victron battery to battery charger from you alternator and you’re ready to drain again. They can be used with your existing charger and connect seamlessly to your solar system.

ARE LITHIUM PRO BATTERIES REALLY 'PLUG & PLAY' ?

Lithium Leisure batteries

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 SMARTIQ SERIES batteries all 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 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 14.2-14.6v.  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.

DO I NEED TO CHANGE MY SOLAR CHARGE CONTROLLER

No, you do not need to change your existing solar charge controller to charge LithiumPro Batteries. 

Modern motorhomes are typically equipped with a solar charge controller to manage energy from the solar panels. However, if your motorhome 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 motorhome 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.

CAN I CHARGE FROM MY ALTERNATOR.?

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.

You will need to put a box in between to regulate the voltage that your alternator outputs.

If your vehicle has stop start technology and you wish to charge from your alternator you will need to fit a Battery to Battery or DC-DC charger. 

I HAVE A SPLIT CHARGE RELAY IS IT OKAY TO USE WITH LITHIUM.?

No, the problem with split charge relays or Voltage-Sensitive Relay (VSR) is they do not monitor the charge level of the leisure battery; they only respond to the voltage of the starter battery. As a result, it will continue to pass charge to the leisure battery as long as the alternator is running and the starter battery voltage is above the VSR’s cut-in threshold. This can potentially lead to overcharging if the leisure battery is full and no additional protection is in place. 

When using a LithiumPro Battery, your battery is safeguarded against overcharging along with many other protections by the advanced Battery Management System (BMS). This sophisticated system provides robust protection to ensure safe and efficient operation.

Why Add an Additional Safeguard?
Relying solely on the BMS for protection is not considered best practice in electrical design. To enhance safety and reliability, it’s highly recommended to use a Battery-to-Battery (B2B) charger when charging lithium batteries from your alternator.

Benefits of a Battery-to-Battery Charger. (B2B charger):

  • Regulates Voltage: Ensures a consistent and appropriate voltage output from your alternator, preventing overcharging or undercharging.
  • Current Regulation: Protects your alternator by controlling the current drawn during charging, preventing potential overheating.
  • Enhances Safety: Adds an extra layer of protection for your electrical system, reducing risks associated with alternator charging.
  • Optimises Charging Efficiency: Maximises charging performance, ensuring your LithiumPro Battery charges efficiently and safely.

By integrating a B2B charger into your setup, you not only protect your battery but also ensure long-term performance and reliability for your electrical system.

MY MOTORHOME HAS STOP-START TECHNOLOGY, CAN I STILL CHARGE FROM MY ALTERNATOR.?

If your vehicle is new and meets EURO 5 emissions or greater ie you have to use ‘Ad Blue’ then your vehicle more than likely has ‘Stop-Start’ technology.  This means the alternator fluctuates the power output at the alternator depending on the vehicles exact requirements. The voltage can fluctuate from 0-16v which is not conducive to charge any battery, so if you wish to charge from your alternator you will need to fit a Battery to Battery or DC-DC charger to regulate the both the voltage and the current the battery will receive.

FREQUENTLY ASKED QUESTIONS

In short, no, it is not compulsory to use a dedicated lithium battery charger to charge LithiumPro batteries. While it is recommended for optimal performance, and preserving the life of your battery it is not essential.  Any normal lead-acid battery charger designed to output a Constant Voltage Constant Current (CCCV) charge profile, between 14.2v-14.6v which 95% of chargers do, then this is fine and safe for LithiumPro batteries. However, charging may take a bit longer and be slightly less efficient compared to using a dedicated lithium charger with a LiFePO4 charge profile.

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.  

For those who prefer to upgrade their charging system for more efficient and faster charging, we have provided a list of chargers that are compatible with our lithium batteries.

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 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.

 

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

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.

The more powerful the charger the quicker it will charger you battery, so the higher the Amperage of the charger the quicker it will charger.

Our recommendations
Batteries under 100ah – use a 20A charger – this should take 5 hours to charger from empty

Batteries over >150ah – use a 30A charger – This should take 5 hours to charge

Larger batteries over 250ah – use multiple charging sources to replenish your battery. Solar, Alternator and Mains. Using your vehicles surplus power to charge your large battery is very efficient. You will need to fit a DC-DC Charger, also know as a battery to battery charger.

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 DIN 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. You can even use you existing charger in most cases. 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 a chinese replacement battery down. Click here for ‘Drop-In’ replacement batteries.

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:

  • In series to increase voltage up to 24V, 36V, or a maximum of 48V.
  • In parallel up to a maximum of 4 batteries for the SMARTIQ SERIES. Or a maximum of 8 batteries for SMARTCOMM SERIES.

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. All LithiumPro Batteries have a safety feature built into the battery to prevent it charging below 0ºc.
