Millertech 12V 190AH Sport Series Lithium Dual Purpose Battery with Bluetooth

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.
