270Ah BullTron Polar | The most powerful LiFePO4 battery in the 95Ah standard DIN size of a lead/GEL/AGM battery.

You are looking for a LiFEPO4 battery for a 1 to 1 exchange with your standard DIN 95Ah lead/GEL/AGM battery.
You have little space, but still want a high capacity and performance to be able to connect a large inverter and charge e-bikes?
We have developed this 270Ah LiFePO4 battery in standard DIN size for this purpose.
By far the largest capacity in standard DIN format.
80% more capacity than LiFePO4 batteries from other manufacturers in standard DIN size.

This battery fits up to 2x under each seat.
This gives you a usable capacity of 540Ah or 6.9kWh under the seat.
This is almost 6 times as much as with 2x95Ah lead/gel/AGM batteries, while at the same time saving 6kg in weight.
This means that there are no more limits to self-sufficiency.

BullTron batteries can also be installed horizontally.

  • Installation is very simple: remove the old battery, insert the new battery, done. BMS, Bluetooth, active balancer and heating - everything you need is included in this lithium battery. As a rule, existing chargers can be retained. If desired, additional batteries can be added and connected in parallel.

    8 reasons to choose a lithium battery from BullTron

    • Developed and assembled in Germany. BullTron is a German manufacturer, so service and repairs are also carried out in Germany.

    • Longevity. With over 7,000 cycles (at 80% DOD), you will enjoy this lithium battery for a very long time.

    • Super compact. Like all BullTron LiFePO4 batteries, the 270Ah variant is also extremely small and therefore fits into the seat console of Ducato, Bulli and Co as well as in intermediate floors and in the space of the existing 95Ah batteries.

    • Integrated powerful heater with the highest possible effectiveness and efficiency (extremely fast and completely uniform heating of all cells) The integrated heater starts at temperatures below 0°C when a charging current is applied. No battery discharge due to the integrated heater.

    • Extremely light. At only 24kg, this battery is up to 85% lighter than a 540Ah lead-acid battery (same usable capacity). Weight saving = 126kg

    • 1-day service (battery problems are rectified in-house within 1 day)

    • 5-year German manufacturer's warranty. Optionally extendable to 10 years.

    • New, lighter, maintenance-friendly technology. The bolted housing can be opened, all cables and control units are bolted - this promises quick, easy and cost-effective repairs, even well beyond the warranty period.


      Optimal lead-acid battery replacement with up to 10 times the service life
      BullTron LifePO4 batteries are an optimal lead-acid battery replacement with all the advantages of lithium iron phosphate batteries.
      They offer a weight reduction of up to 85%, high energy reserves and stable voltage even under extreme loads.
      The batteries have been specially developed to achieve an optimum ratio of size, weight, performance and service life.
      An extremely long service life is guaranteed even with regular deep discharges (4000 cycles at 100% DOD/discharge depth or 7000 cycles at 80% DOD/discharge depth) thanks to the latest lithium technology, making BullTron® batteries the optimum supply battery.


    The battery is suitable for 12V & 24V systems.

    - Parallel connection 12V is possible (increase in capacity)
    - Series connection of 24V, 36V, 48V is also possible


    Advantages of BullTron batteries
    - assembly & installation in Germany
    - 5-year German manufacturer's warranty, optionally extendable to 10 years
    - service, maintenance and repair in Germany (within 1 day)
    - bolted housing (can be opened)
    - all cables and electronic components replaceable (bolted)
    - use of high-quality & long-life components durable components
    - up to 75% longer cycle life than other LiFePO4 batteries
    - up to 45% smaller and up to 35% lighter than other LiFePO4 batteries
    - battery sizes up to 540Ah suitable for under-seat mounting
    - automatic battery shutdown in the event of a short circuit

    Safest lithium technology (LiFePO4)
    BullTron batteries use lithium iron phosphate technology (LiFePO4), currently the safest lithium technology on the market. All batteries consist of powerful and very durable (LiFePo4) cells and an integrated battery management system (BMS). The BMS permanently protects the individual cells and the entire battery against over/under voltage, over/under temperature, overload and short circuit (automatic shutdown without damage).
    The BMS effectively prevents premature battery failure due to external influences or incorrect use.
