  • Why Buy From Us
  • The Epoch 12V 300Ah Pro Series Dual Purpose battery starts compatible outboards and powers house loads from one BCI Group 8D LiFePO4 battery. It stores 3.84kWh and weighs 81 lb, far lighter than typical 130-160 lb Group 8D lead-acid batteries.

    A high-output BMS delivers 1,000A for up to 5 seconds and 300A continuous, with internal heating, an IP67 enclosure, Bluetooth monitoring and CAN Link ports. It is rated for 6,000+ cycles and backed by an 11-year manufacturer warranty when registered within 90 days of purchase.

    Key Features

    • Cranking power: 1,000A for up to 5 seconds and 800A for up to 10 seconds for engine starting and start-up surges.
    • 300A continuous output: 300A continuous (150A recommended) for house loads and 3,000W-class inverter systems.
    • Fast charging: Accepts up to 300A from all sources combined, with up to 150A recommended.
    • Self-heating: With a charger connected in cold weather, the heating film warms the battery to 10°C (50°F) before charging, down to -20°C (-4°F).
    • IP67 enclosure: Dust-tight and protected against temporary immersion to 1 m for 30 minutes.
    • Bluetooth and CAN: The Epoch Pro app shows battery data and installs firmware updates; CAN Link in/out ports network a bank.
    • Series and parallel: Up to 4 in series (48V class) or 16 in parallel (4,800Ah, 61.44kWh at 12V).
    • 6,000+ cycle life: Rated at 0.2C and 80% DoD to 80% of initial capacity at 25°C.

    • Up to 4 in series for 24V, 36V or 48V
    • With batteries in series, up to 4 strings in parallel (4S4P maximum: 51.2V, 1,200Ah, 61.44kWh)
    • Use matched DP12300H batteries within 0.5V of each other

    Communications

    • Up to 150A recommended; 300A maximum from all sources combined
    • 15.4V is a listed maximum, not a charger target
    • For alternators, use a DC-to-DC charger or lithium-ready regulation

    Suitable For:

    • Marine engine starting for compatible outboards
    • Dual-purpose boat systems combining starting and house power
    • Marine electronics, sonar, livewell and bilge pumps
    • RV, van and overland 12V house power
    • 3,000W-class inverter systems
    • Solar, off-grid, cabin and backup power
    • 24V to 48V banks

    Please Note: Rated by peak current and duration, not CCA: verify the engine maker's battery requirements, alternator, wiring and charging profile before replacing a starting battery.

    Please Note: Keep enough charge in reserve to start the engine.

    Please Note: IP67 is not for submersion, water jets or pressure washing; do not install in a bilge or where standing water collects.

    Please Note: Mount upright only, never on its side or upside down; install a DC-rated main fuse close to the positive terminal.

    Please Note: Not a drop-in replacement for every lead-acid installation: check tray, hold-downs, lid clearance and cable reach.

  • Epoch Batteries Limited Warranty

    Warranty Period
    11-year manufacturer warranty; register within 90 days of purchase

    Epoch Batteries-branded products are covered against qualifying defects in materials and workmanship for the applicable warranty period, subject to Epoch's model-specific remedy schedule and the terms of its warranty policy. Epoch-branded chargers carry a 2-year limited warranty and accessories (such as fuel gauges and voltage reducers) a 1-year limited warranty, from the original purchase date.

    Registration
    Register your battery with Epoch within 90 days of purchase for full warranty coverage. If it is not registered within that time, the warranty period begins from the battery's original manufacturing date. Proof of ownership is required for any claim, and coverage is non-transferable and applies only to the original purchaser.

    Remedy
    After inspection and testing, Epoch will provide the applicable remedy for a qualifying manufacturing defect: an approved repair, a replacement, or a comparable-product offer according to the model's schedule. Typical repair turnaround is 3–10 business days once the product is received.

    Exclusions
    Coverage may be denied when a failure is caused by misuse, improper handling, installation or storage, or use outside the product's specifications. Examples include an unsecured battery; loose, corroded or improperly connected terminals; series or parallel connections beyond the manufacturer's recommendations; reverse polarity or short circuits; impact, fire or water submersion; storage above 140°F or below -40°F; prolonged storage fully discharged or batteries left uncharged for more than three months; poor crimps, undersized cables or damaged wiring; opened, modified or tampered products; and use in applications the battery was not designed for, including repeated engine starting on non-cranking models.

    Obtaining Warranty Service
    Start a claim through the Epoch Batteries Warranty Portal with your model and serial number, proof of purchase, a description of the issue and supporting photos or videos. If approved, Epoch provides an RMA number and packing instructions. Do not ship a product without a valid RMA. The customer arranges and pays for shipment to Epoch, packaged in compliance with lithium battery shipping rules. Epoch Batteries can be reached at 1-888-501-1846 or support@epochbatteries.com.

    Visit Epoch's Warranty Page to review the full warranty terms.
