Epoch 12V 300Ah Marine Lithium Battery – Pro Series LiFePO4 | Cranking & Deep Cycle Dual Purpose

Description

One battery can supply both engine-starting power and deep-cycle energy when a system requires a dual-purpose design. TheEpoch 12V 300Ah Pro Series Dual Purpose Lithium Batterystores 3.84 kWh of energy at a nominal 12.8V and is listed for single-battery engine-start and house-power applications.

The battery is rated at 1,000 cold-cranking-amp equivalent, 250A continuous discharge, and 1,000A surge discharge for three seconds. It includes an internal heat strip, IP67 waterproof protection, Bluetooth functionality, dual-purpose-optimized battery management features, and M8 stainless-steel terminals. Its stated cycle life exceeds 4,000 cycles at 80% depth of discharge.

Battery and Charging Compatibility

This is a 12.8V nominal LiFePO4 dual-purpose battery for 12V systems; it is not a battery charger. It is listed for a single battery that supports engine starting and house power, so the engine, charger, alternator-charging equipment, and connected loads must be compatible with the battery system.

The 1,000A cold-cranking-amp equivalent and three-second surge rating describe the listed starting-power capability. Confirm engine-start requirements, charger settings, and the manufacturer’s LiFePO4 guidance before connecting the battery to an engine or house electrical system.

Installation and System Considerations

The battery uses M8 stainless-steel terminals, measures 13.6 in. by 7.5 in. by 9.6 in., and weighs 66.1 lbs. It has an IP67 waterproof enclosure, internal heat strip, Bluetooth functionality, and listed dual-purpose-optimized battery management features. Installation should follow the battery manual and the electrical requirements applicable to the vessel.

Warranty and Support

Warranty information is not included in the listed product data. Review the manufacturer documentation for product details, setup, and warranty coverage.

Before Ordering the Epoch 12V 300Ah Pro Series Dual Purpose Lithium Battery

Before ordering, confirm that your system is compatible with a 12V-class, 12.8V nominal LiFePO4 dual-purpose battery. Review the 300Ah capacity, 3.84 kWh energy rating, 1,000 CCA-equivalent rating, 250A continuous output, 1,000A three-second surge rating, IP67 rating, 66.1 lb weight, and physical dimensions. You should confirm compatibility with your engine, charger, alternator, and vessel electrical system before purchase.
