The Epoch 12V 120Ah Pro Series LiFePO4 Cranking & Deep Cycle Battery is designed to deliver the perfect balance of starting power and deep-cycle endurance for today’s high-performance marine applications. Engineered with LiFePO4 lithium technology, this dual-purpose battery provides superior energy density, cold-cranking ability, and cycle life — making it ideal for outboard engines up to 250 horsepower.
With 1100 CCA equivalent cranking power and a 150A continuous discharge rating, the Pro Series delivers instant starts and sustained power for trolling motors, electronics, and onboard systems. It’s built for extreme environments with IP67 waterproof construction, internal heating for sub-zero charging, and Bluetooth monitoring via iOS and Android apps.
The battery’s integrated Smart BMS ensures total protection against over-voltage, short circuits, and temperature extremes, while CANBus compatibility allows seamless communication with Victron Cerbo GX systems. Optional upgrades include a 5” touchscreen battery gauge and NMEA 2000/Inverter communications box, giving boaters full visibility and integration with onboard electronics.
With over 6000 life cycles, UL-certified components, and a robust 11-year warranty, the Epoch 12V 120Ah Pro Series is the ultimate marine-grade lithium battery for both starting and deep-cycle use.
