• Lithium-ion batteries revolution will take you to a new era

    Store energy like never before

  • the MISSION

    We want to provide the best Lithium-ion batteries for classic and sports cars.

    Get the best technology ever to crank your engine.

    This is a lightweight with power amps to deliver!


    At Atomique Batteries Co., we handcraft State-of-the-Art Lithium ion batteries in a strong-resistant carbon casing.


    Our batteries set a precedent that will make you forget about old and heavy lead acid batteries. They are engineered with an electronic battery management system that will make them last for a long time.

  • Atomique's bombs

    We are dropping our first Amp-delivery devices!

    20 Amps.hrs

    The small beast

    This is our lightest and smallest battery pack: with a 20Ah energy capacity and 12.8V tension, it weighs only 3 kg. With a CCA of 800 Amps, this battery will crank even the most powerful engines

    It is equipped with a BMS that will protect the cells from short-circuit, overcharge and deep discharge for a maximum lifetime.

    Ideal for racing cars and classics.

    40 Amps.hrs

    Powerful and strong capacity

    This pack is design to replace any 12.8V lead acid battery of any type for all applications. It has a 40Ah energy capacity and 12V tension, for a 6 kg weight.

    It is equipped with a BMS that will protect the cells from short-circuit, overcharge and deep discharge for a maximum lifetime.

    Ideal for modern sports cars.

    120 Amps.hrs

    Great capacity

    This pack of 120Ah energy capacity and 12.8V tension weighs only 18 kg. It is designed as storage battery for high autonomy demand like yachts, boats, caravan, etc...

    You can use three of these batteries to make a 360 Ah (4.32kWh) pack for renewable energy storage at home.

    It is equipped with a BMS that will protect the cells from short-circuit, overcharge and deep discharge for a maximum lifetime.

    160 Amps.hrs

    Huge capacity

    This pack of 160Ah energy capacity and 12.8V tension weighs 21 kg. This battery would replace 320Ah of lead-acid batteries for the same autonomy. You can associate in parallel a large number of this battery to make big packs for energy storage of tens of kWh.

    It is equipped with a BMS that will protect the cells from short-circuit, overcharge and deep discharge for a maximum lifetime.

    Who are we ?

    Atomique Batteries SAS is a young French Start-Up.

    Created in 2016 by former battery engineers from French public Research Institute CEA, our passion for car racing competition, sailing and electrochemical energy storage lead us to build our own vision of the perfect Lithium-ion battery for classic and modern sports and racing cars, and also cruiser-racer yachts.

    All our production is handcrafted in our workshop in France, near Aix-en-Provence.

    What are the other applications ?

    Our batteries can be used as a replacement for any 12V lead acid batteries.

    The huge gain in weight allowed by the replacement of a lead acid battery by our Lithium-ion batteries can be an amazing asset in a lot of applications.

    For example, they can be used in sport proto sailing boats, or cruising racers, allowing a weight loss up to 100 kg.

    In caravaning, the much higher longevity of our batteries compared to lead acid can play a decisive role in creating the perfect energy storage device for campers.

    In a long-term goal, Atomique Batteries wants to produce batteries for home storage suitable with a renewable energy home production, and integrated UPS system (Uninterruptible Power Supply).

    Why Lithium-ion tops lead acid batteries ?

    Lead acid was for 19th and 20th, Lithium-ion is for 21th century !

    Lithium is the lightest metal in the Universe, and is very reactive. Its properties made it the most suitable element for energy storage. This is why it is used widely in all electronic devices (laptop batteries, smartphones, cameras, etc ...) and Li-ion batteries are now targeted as the ideal energy storage solution for applications like electric cars as the Tesla Model S.

    Lead acid batteries on the other hand are a very old technology, with poor performance in energy density, and extremely polluting, but still widely used because of their very low price. Their lifetime is short, with only 500 cycles of charge and discharge, against 5000 cycles for Lithium-ion. It means that our batteries can last 10 times longer than a lead acid battery.

    Is Lithium-ion Batteries safe enough for racing purpose ?

    The safest technology. Rigorously tested.

    Our batteries are made with Lithium Iron Phosphate (LiFePO4) cells. This chemistry does not ignite fire in contact with air like other lithium chemistry. It is the safest and most eco-friendly chemistry developed so far (it contains no heavy metals like Pb, Cd or Co). We use exclusively grade A cells from top manufacturer.

    All our batteries are equipped with an eBMS (electronic Battery Management System) that enhance even more the safety and reliability for a maximized longevity.

    The super-strong carbon fiber casing designed for extreme environments is the ultimate protection for the cells and electronic inside. All our batteries are compliant to the UN38.3 and IEC 62281, which include extreme mechanical and electrical tests.
