UBL-12V-300Ah-PRO LiFePO4 supply battery

The new Ultimatron PRO series is here! Smaller housing and less weight with the same performance (same size as UBL-12V-200Ah).

ULTIMATRON 's deep-cycle batteries consist of Class A lithium cells and impress with their high performance , which remains stable even under heavy loads . The integrated Battery Management System (BMS) provides comprehensive cell protection by continuously balancing the cells and constantly monitoring both performance and temperature. The battery can be conveniently connected to a smartphone or tablet via Bluetooth 4.0 , allowing you to keep track of everything in the app. ULTIMATRON offers deep-cycle batteries in various designs and series , capacities, and operating voltages: UBL series , ULM series (under-seat) , and ULS series . Some models are available with or without heating (integrated heating mat) , which, as an additional option, allows the battery to be used even in sub-zero temperatures by maintaining its operating temperature.
