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. 12V 190AH dual-purpose LiFePO4 battery for starting and deep-cycle power High cranking amps for large outboards with reserve capacity for electronics BCI Group 31 size with heavy-duty reclosable case and secure strap grooves Bluetooth-enabled for real-time monitoring via the MillerTech App IP65 marine-rated with rubber gasket seal and stainless-steel vent Large heavy-duty terminals prevent heat build-up during high demand Specifications: Capacity: 190AH Voltage:12.8V BMS: Yes Chemistry: LFP Efficiency: 98% Memory: None Max Charge/Voltage: 14.6V Cut-off Voltage: 10.5V Max Charge/Discharge Current: 190A Operating Temp: -4AdegF - 140AdegF Low Temp Charging Protection: Yes Cell Type: Prismatic Group Size: 31 Bluetooth: Yes Size: 13" x 6.75" x 9" Weight: 42 lbs.
