185Ah BullTron Polar | the small, powerful lithium battery in the original housing of a 95Ah lead-acid battery

Small camper or van, limited space, moderate power consumption - this 185Ah lithium battery was designed for precisely these needs.
This battery has the same dimensions, mounting points, and terminal connections as an original 95Ah lead/GEL/AGM battery.

This 185Ah lithium battery replaces a GEL or AGM battery with a capacity of up to 370Ah, at 12V. It takes up much less space and is significantly lighter than conventional lead-acid batteries.
BullTron batteries can also be installed horizontally.

Installation is incredibly simple: old battery out, new battery in, done. BMS, Bluetooth, active balancer, and heating – this lithium battery includes everything you need. Existing chargers can usually be retained. If desired, additional batteries can be added and connected in parallel.

8 reasons to choose a BullTron lithium battery

• Developed and assembled in Germany. BullTron is a German manufacturer, so service and repairs also take place in Germany.

• Longevity. With over 6,000 cycles (at 80% DOD), you will enjoy this lithium battery for a very long time.

• Super compact. Like all BullTron LiFePO4 batteries, the 185Ah version is extremely small and therefore fits into the seat console of Ducato, Bulli, etc., as well as into raised floors and in the place of 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 discharge of the battery by the integrated heater.

• Extremely light. At just 16kg, this battery is up to 85% lighter than a 370Ah lead-acid battery (same usable capacity). Weight savings = 89kg

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

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

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

  
  Optimal lead-acid battery replacement with up to 10 times the lifespan
  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 optimal ratio of size, weight, performance and lifespan.
  An extremely long service life is guaranteed even with regular deep discharge (3500 cycles at 100% DOD/depth of discharge or 6000 cycles at 80% DOD/depth of discharge), thanks to the latest lithium technology, making BullTron® batteries the optimal 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

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 from over/under voltage, over/under temperature, overload and short circuit (automatic shutdown without damage).
Premature battery failure due to external influences or incorrect use is effectively prevented by the BMS.
