The Millertech 12V 190AH Sport Series Lithium Dual Purpose Battery with Bluetooth is built for anglers and boaters who demand maximum starting power and deep-cycle performance from one battery. Delivering the cranking amps to start even the largest outboards while supplying more than enough reserve capacity to run multiple high-draw electronics and graphs for over 8 hours, this LiFePO4 Group 31 unit redefines marine power expectations. A custom-molded, heavy-duty reclosable case ensures long-term serviceability, with integrated strap grooves for secure mounting and straightforward maintenance, even years down the line. Oversized heavy-duty terminals prevent heat build-up under peak loads, while a thick rubber gasket seal and marine-grade stainless-steel breather vent provide IP65-rated protection against water intrusion and condensation. Integrated Bluetooth technology connects directly to the MillerTech App, giving you detailed, real-time battery performance data across multiple units in one place, so you can power your boat with complete confidence.
