12v 150AH Lithium Battery ARCTICXTREME


Introducing the 12v 150AH Lithium Battery from LithiumPro Energy:

The premium range from Lithium Pro Energy, the ARCTICXTREME with SmartIQ technology. The 12V 150AH Lithium Battery has been designed for power hungry devices and applications. The ARCTICXTREME is the UK’S most powerful lithium battery in a standard DIN H8 case. Using Advanced BMS technology the ARCTICXTREME can deliver up to 200 amps of continuous power, enabling you to run up to a 2500W inverter continuously with only a single battery. The next most lithium powerful battery in this size case is 110AH and it can only run a maximum of 1400W before the BMS will shut down the system.
The ARCTICXTREME as its names suggests has been designed for use in cold climates.  Our advanced heating technology facilitates safe charging capability down to -20ºC, ensuring continued operation in sub-zero climates.

The ARCTICXTREME battery comprises Grade A LiFePO4 prismatic cells of the highest quality. We ONLY use traceable Grade A Prismatic cells in all of our range.
Designed and engineered in the UK we have retained the standard SAE Automotive style DIN battery size with familiar brass terminal posts. In terms of size, this battery is a like-for-like lead acid-replacement. This battery is a Plug & play replacement, meaning you do not need to replace your existing battery cables or connecting leads.  The battery has the same base rail, allowing it to be secured into position just like before. It’s ideal for motorhomes, caravans, or camper vans. Simply remove your old lead acid battery and replace it with the smaller, lighter, and more powerful lithium ARCTICXTREME weighing just 16kgs.

This battery is a genuine ‘PLUG & PLAY’ direct replacement for your lead-acid battery. If your motorhome or caravan has a lead-acid CCCV based charger that charges between 14.2v -14.6v you can install this battery and it will charge just fine. It will fit in exactly the same place as your old 95-110ah Lead acid battery and will charge using your existing CCCV charger.

Of course, should you wish to upgrade to a more powerful, dedicated lithium charger with a LiFePO4 profile it will charge much faster and more efficiently, but it is not a requirement with our batteries. See here for lithium chargers

Our Premium SmartIQ Series features the latest Bluetooth 5.0 technology, enabling you to monitor your batteries’ health in real-time. You can track the state of charge level, voltage, power, current, temperature, and much more. All our Premium SmartIQ Series batteries come with a full 5-year warranty and have an expected lifespan exceeding 10+ years.

You can fit two SMARTIQ SERIES batteries perfectly under the seat of a Fiat Ducato’s, Peugeot Boxers, Citroen Relays, Merc Sprinter, VW Crafter, Transit Custom. CLICK HERE TO SEE INSTALLATION

All our Premium Smart IQ range batteries come with a full 5-year warranty, with an expected lifespan exceeding 10+ years.

lithium leisure battery terminals


Lithium Iron Phosphate batteries (LiFePO4) can be used as a versatile alternative to 12v Lead-acid leisure batteries in most situations.

LithiumPro Energy SMARTIQ SERIES batteries use a DIN Standard size battery cases, that fit perfectly into your motorhome, caravan, campervan or boat. This  battery is the same size & shape as your old lead-acid battery.  They also feature standard brass terminals posts, so there is no requirement to change you battery leads or connectors.  We have also retained the mounting rail at the base, so it can be safely and securely fixed into existing your battery tray. There is no need to find creative ways in which to securely mount your new lithium battery. 

LithiumPro batteries can be charged with most Lead acid chargers that charge between 14.2-14.6v.  A dedicated lithium LiFePO4 charger is ideal as it will charge faster and more efficiently but is NOT required with Lithium Pro lithium batteries.  Choose Lithium Pro  batteries for a genuine hassle-free ‘Drop In’ Lead-Acid replacement.

How to chose the right lithium Battery.

Its important to consider the following factors when choosing the right Lithium Battery for your application:

  • CERTIFICATION, safety is a critical factor, so make sure you chose a battery that meets all the standards for sale. UKCA for UK, CE for Europe, ROHS Restriction of Hazardous Substances, RED Radio Equipment Directive if it has Bluetooth. UN38.8 approval – United Nations governs approval for the transportation of Lithium via rail, road, sea and air.  Are the batteries Verified and approved by the NCC?
  • CAPACITY, how much capacity do you require for your setup. This is rated in ampere hours (100ah)
  • POWER RATING, this amount of power your battery hold measured in watt/hours. 100ah 1280wh
  • CHARGE/DISCHARGE CAPABILITY, is a very important consideration when choosing the right battery for you. This capability is measured in Amps and is controlled by the Battery management System BMS. This governs the amount of amps that can pass through the battery when charging and discharging. This will limit the size of your inverter that you can run and at what rate you can charge the battery. So chose carefully.
  • CELL TYPE, Lithium batteries have advanced over the last 5 years and continue to advance at a rapid pace. Initially cylindrical cells were used in most LiFePO4 Lithium Iron Phosphate batteries. They have now been replaced with lighter, more efficient prismatic cells. These allow more flexibility in packaging in smaller spaces and produce far higher cyclic capacity.
  • CYCLES, Prismatic cells are advancing due to the advancement of EV, Electric Vehicles driving the technology forward thus producing upwards of 4000 -8000 cycles, thats 11-20 years of daily use. Whereas the older cyclindrical cells are limited to 2500cycles.
  • SIZE & SHAPE, is it compact enough or has a low profile  to fit under the seat of your motorhome. 
  • CUSTOMER SUPPORT, Is the company buying from based in the UK, or China?  Do they offer customer support, technical backup, free warranty repair or replacement. Can you talk to them on the phone?
