BullTron 300Ah incl. Smart BMS with 200A continuous current & Bluetooth app
300Ah Polar LiFePO4 12.8V battery with Smart BMS, Bluetooth app and heating
The POLAR model // Frost-proof charging down to -30°C
The Polar versions have been equipped with a newly developed, very powerful and effective 130W heater.
300Ah BullTron Polar | the compact lithium battery for maximum energy
This 300Ah lithium battery replaces a GEL or AGM battery with a capacity of up to 600Ah at 12V. It takes up much less space and is much lighter than conventional lead batteries. The BullTron batteries can also be installed lying down.
Installation is extremely simple: remove the old battery, put in the new one, and you're done. BMS and Bluetooth, this lithium battery has everything you need. Existing chargers can usually be retained. If desired, a second battery 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 also take place in Germany.
- Longevity. With over 6,000 cycles (at 80% DOD), this lithium battery promises to last a very long time.
- Super compact. Like all LiFePO4 from BullTron, the 300Ah version is extremely small and therefore fits in the seat console of Ducato and Co as well as in intermediate floors.
- Extremely light. At only 25kg, this battery is up to 85% lighter than a 600Ah lead battery (same usable capacity). Weight saving = 143kg
-
Integrated powerful heater with the highest possible effectiveness and efficiency (extremely fast and completely even heating of all cells). The integrated heater starts at temperatures below 0°C when a charging current is applied. The integrated heater does not discharge the battery.
- 1 day service (battery problems are fixed in-house within 1 day)
- 5 years German manufacturer warranty.
- New, lighter, maintenance-friendly technology. Components are neither glued nor welded, the screwed housing can be opened - this promises simple and cost-effective repairs, even well beyond the warranty period.
Optimal lead battery replacement with up to 10 times longer service life
BullTron LifePO4 Batteries are an optimal lead battery replacement with all the advantages of lithium iron phosphate batteries.
They offer a weight reduction of up to 80%, high energy reserves and stable tension even under extreme loads.
The batteries have been specially developed to achieve an optimal ratio of size, weight, performance and service life.
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 and makes BullTron® batteries the optimal supply battery.
The battery is only suitable for 12V systems.
- Parallel connection is possible (increase in capacity)
- Series connection 24V, 36V, 48V is also possible

Safest lithium technology (LiFePO 4 )
BullTron batteries use lithium iron phosphate technology (LiFePO 4 ), currently the safest lithium technology on the market. All batteries consist of powerful and very long-lasting (LiFePo4) cells and an integrated battery management system (BMS). The BMS permanently protects the individual cells and the entire battery against over/undervoltage, over/undertemperature, overload and short circuit (automatic shutdown without damage).
The BMS effectively prevents premature battery failure due to external influences or incorrect use.
