Epoch Pro Series Dual-Purpose LiFePO4 Batteries (Heated, Bluetooth, Victron-Ready)

The Epoch Pro Series is a true dual-purpose LiFePO4 battery — it delivers serious engine-cranking current and deep-cycle house power in one case, which makes it a favorite for boats running outboards as well as a house bank. Both models combine integrated self-heating for cold-weather charging, built-in Bluetooth, native Victron GX communication over CAN, and a rugged IP67 sealed housing. With a 6,000+ cycle rating, it's built to be installed once and forgotten.

Available as a Group 27-style 12V 120Ah and a Group 8D 12V 300Ah, so you can match cranking and capacity to your setup.

Key Features

• Dual-purpose cranking + deep cycle — strong starting current (up to 1,100 CCA / 1,000 A peak on the 300Ah) for outboards up to 250 hp, plus full house-bank capacity.
• Integrated self-heating — warms the cells for safe charging in sub-freezing conditions.
• Bluetooth monitoring — state of charge, voltage, current, and health from the Epoch app, with over-the-air firmware updates.
• Victron-ready — BMS-CAN communication links the whole battery string to Victron GX devices for managed charging via DVCC.
• IP67 sealed housing — dust-tight and protected against temporary submersion for marine-grade durability.
• Smart BMS — over-current, short-circuit, and high/low-temperature protection.
• Expandable — up to 4 in series (to 48V) and 16 in parallel.
• 6,000+ cycle life, maintenance-free.
