Bulltron Polar

BullTron LifePO4 batteries are an optimal replacement for lead batteries, offering all the advantages of lithium iron phosphate batteries. They provide a weight reduction of up to 85%, high energy reserves, and stable voltage even under extreme loads. The batteries are specifically designed to achieve an optimal balance of size, weight, performance, and lifespan. An extremely long lifespan is guaranteed even with regular deep discharges (3500 cycles at 100% DOD/Depth of Discharge or 6000 cycles at 80% DOD/Depth of Discharge) thanks to lithium technology, making BullTron batteries the ideal supply battery. The battery is suitable for 12 V - 48 V systems. Parallel connection at 12 V is possible (increasing capacity), and series connection at 24 V, 36 V, and 48 V is also feasible.

Advantages of BullTron batteries:

• Assembly and installation in Germany
• Service, maintenance, and repair in Germany (within 1 day)
• Screwed housing (can be opened)
• No glued or welded components
• All components (cells and BMS) are replaceable (screwed)
• Use of high-quality and durable components
• Up to 75% higher cycle lifespan than other LiFePO4 batteries
• Up to 45% smaller and up to 35% lighter than other LiFePO4 batteries
• Battery sizes up to 480 Ah suitable for under-seat installation
• Automatic shutdown of the battery in case of a short circuit

BullTron Polar, like Basic, but with a Bluetooth app and heating for use from -30°C to 60°C. The small, powerful lithium battery for small campers or vans with limited space. The 105 and 150 Ah versions have the same dimensions, mounting points, and terminal connections as an original 95 Ah (lead/AGM/GEL) battery. The 200 and 400 Ah versions replace a GEL or AGM battery with a capacity of up to 400 or 600 Ah, respectively.
