Ultimatron ULM-12V-500H | 500Ah LiFePO4 under-seat power battery (with heater)

The ULTIMATRON ULM-12V-500H is a powerful lithium-ion supply battery specifically designed for campers and motorhomes with high energy demands. With an impressive capacity of 500 Ah and an energy output of 6,400 Wh at 12.8 V, it provides ample power for demanding applications. Despite its high capacity, the battery maintains compact dimensions of 340 × 356 × 190 mm, making it ideal for space-saving installations. It supports a continuous discharge current of up to 300 A, making it the perfect choice for power-intensive consumers and large inverters. A special feature is the integrated 80 W heating foil, which enables winter operation. This heating function works at temperatures ranging from -35 °C to +5 °C and activates automatically when an external charging current of about 7 A is present, without burdening the battery capacity. The LiFePO4 technology ensures longevity and safety, while the integrated battery management system (BMS) protects the battery from overcharging, overvoltage, and overheating.

• 500 Ah capacity for high energy requirements
• Integrated heating foil for winter operation
• Continuous discharge current of up to 300 A
• Durable LiFePO4 technology with BMS.
