ULM-48V-100Ah LiFePO4 supply battery

This ULTIMATRON leisure battery was specifically designed for use in electric motorboats and offers maximum performance, even under demanding conditions on the water. Equipped with premium Class A lithium cells, its performance remains consistently stable even under intensive use – ideal for long journeys and challenging maneuvers.

Thanks to the integrated battery management system (BMS), the cells are optimally protected and continuously monitored. This ensures not only safe operation but also an extended battery lifespan – crucial for boat owners who value reliability and longevity. Via Bluetooth 4.0, you can conveniently monitor the battery performance using your smartphone or tablet, so you always have an overview of the condition and remaining capacity – whether during a relaxing trip or intensive use.

ULTIMATRON offers a wide range of batteries that are ideal for campers, boats and more: from the UBL series to the space-saving ULM series (under-seat) to the powerful ULS series.
