- 12V 300Ah Group 8D Dual-Purpose LiFePO4 (3.84kWh): The ultimate marine and RV drop-in upgrade. Combines massive deep-cycle energy storage with heavy-duty engine cranking power, all inside a standard Group 8D physical footprint.
- True Cranking Power & High Output: Delivers an astonishing 1,000A peak discharge (for 5 seconds) and 800A (for 10 seconds) to reliably start marine engines, alongside a massive 300A maximum continuous charge/discharge rate to effortlessly run heavy house loads and 3,000W+ inverters.
- Seamless Victron CANBUS Integration: Features native CAN communications for the entire string of batteries, allowing for plug-and-play integration, closed-loop charging, and advanced monitoring directly within the Victron ecosystem.
- IP67 Waterproof & Sub-Zero Heated: Encased in a fully sealed, submersible housing (up to 1 meter deep) with internal self-heating technology that ensures safe, reliable charging in freezing, sub-zero conditions.
- Smart Bluetooth with OTA Updates: Monitor real-time capacity, voltage, and battery health via the free Epoch iOS and Android apps, featuring built-in support for Over-The-Air (OTA) firmware updates to keep your battery's software optimized for years to come.
- Massive Scalability (Series & Parallel): Highly versatile architecture allows you to wire up to 4 batteries in series (for up to 48V systems) and up to 16 batteries in parallel to build an ultra-high-capacity energy bank.
- Expandable Tech Ecosystem: Built to adapt, with built-in readiness for upcoming Epoch accessories including an external touch-screen battery gauge and an advanced communications box for broader inverter and NMEA2k compatibility.
- Advanced Smart BMS Protection: The integrated Battery Management System automatically guards against over-current, short circuits, and extreme high/low temperatures to protect your investment.
- 6,000+ Cycle Life & 11-Year Warranty: Exceptional, maintenance-free longevity boasting over 6,000 cycles (significantly higher than standard lithium), backed by an industry-leading 11-year manufacturer warranty.

Recommended charging settings:
To properly charge your Epoch Batteries, you will want to verify that any charging component in your system is capable of being programmed for the following specifications. Charging components can include, but are not limited to converters, inverter chargers, solar charge controllers, DC to DC chargers, etc.
Bulk/Absorption: 14.2V – 14.6V
Absorption Time: Two batteries in parallel connections require 30 minutes 200Ah
Float: 13.4V – 13.8V
Equalization: 14.4V/ Disabled
Temperature Compensation: 0/Disabled
Charge Rate: 50% of the battery or battery bank capacity
Battery Charge Temperature Range: 32°F (0°C) to 131°F (55°C)
Battery Discharge Temperature Range: -4°F (-20°C) to 140°F (60°C)
Cell Charge Temperature: 32°F (0°C) to 131°F (55°C)
Cell Discharge Temperature: -4°F (-20°C) to 140°F (60°C)
NOTE: Not all chargers are capable of multistage charging. If yours is not, you will want to verify it can be programmed for the Bulk/Absorption voltage and have the other items mentioned disabled if applicable. Consult your charger's manual or the manufacturer.
