Epoch Battery 12V 460Ah 5.89kWh V2-T Elite Series, Heated and Bluetooth with Victron Comms, Mobile and Outdoor LiFePO4 Battery

The V2-T includes an Eaton Class T fuse (model JJN-500), rated at 500A with a 20kAIC interrupt rating at 160VDC. Previous Epoch Elite models required the installer to source and mount an external fuse for battery source protection. The V2-T includes that fuse in the enclosure, which simplifies installation, shortens unfused conductor runs, and aligns with ABYC source-protection requirements. If you're a professional installer, this means a shorter bill of materials and a cleaner panel layout. If you're building your own system, it removes one of the trickier decisions around fuse selection and placement.

Yes. The V2-T Elite communicates natively over CAN-bus at 500 kbit/s with Victron GX devices. It appears as a recognized battery and publishes real-time SOC, voltage, current, temperature, and charge/discharge limits. With DVCC enabled and the controlling BMS set to Epoch, the battery actively manages charge behavior across your connected Victron inverter/chargers, solar charge controllers, and DC-DC converters.

The battery works with any 12V charger, inverter, or charge controller configured to a LiFePO4 charge profile (CC/CV, 14.52V max charge voltage, no equalization). The Victron CAN-bus integration is an advanced feature for managed battery communication, but it's not required for the battery to function. If you're using a non-Victron system, the battery still provides full BMS protection, Bluetooth monitoring, and heating — you'll just configure your charge sources manually to match the published charge profile rather than relying on CAN-bus communication for automatic control.

When charging, the heater automatically activates when the cell temperature drops to 41°F, and it draws 180.67W at 14.6Vdc to warm the cells. Once the cells reach 50°F, the heater shuts off and charging proceeds normally. When discharging, the heater deactivates at 41°F, and the battery can continue discharging down to -4°F without heating.

The heater is powered by the battery itself, so it does draw from stored energy. In practice, the draw is modest relative to the battery's 5.89kWh capacity, and it only runs during the brief warm-up period before charging begins. The alternative — a low-temperature cutoff that simply refuses to charge until the environment warms up on its own — can leave you without power for hours or days in cold conditions.

IP67 means the enclosure is completely dust-tight (no ingress of dust) and can be immersed in water up to 1 meter deep for up to 30 minutes. This makes it suitable for marine engine rooms, RV compartments, and outdoor stationary setups where spray, condensation, and occasional flooding may occur. That said, IP67 assumes all service points are sealed correctly after installation. If you leave terminal covers off or cable glands unsealed, the rating doesn't apply.

The PC+ABS case material is also rated UL94 V-0, meaning it's self-extinguishing.

The V2-T Elite battery supports up to 16 units in parallel (for a maximum of 94.2kWh). Every unit in a bank or string must be the same model.

Configure all charge sources like solar charge controllers, alternator regulators, and inverter/chargers to a CC/CV (Constant Current/Constant Voltage) LiFePO4 profile with a constant voltage target of 14.52V (3.63V per cell) and a cutoff current of 0.02C (approximately 9.2A for this battery). Do not enable equalization, desulfation, recondition, forced absorption extension, or chemistry auto-detect modes. If your charger has a "lithium" or "LiFePO4" preset, that's typically the correct starting point, but you will need to verify that the voltage and cutoff values match the published specs.

The V2-T is rated for over 3,500 cycles at 25°C with 0.5C charge, 1C discharge, and 70% depth of discharge, retaining at least 70% of the original capacity after this. At one cycle per day, that is 9-10 years of heavy use before reaching 70% capacity. Even then, the battery continues to function with gradually reduced capacity. Cycle life varies with depth of discharge, temperature, and charge/discharge rates. Shallower cycles and moderate temperatures significantly extend life. Epoch includes an 11-year manufacturer warranty.

The internal Class T fuse (Eaton JJN-500) is designed to blow only under catastrophic fault conditions, like a dead short or an extremely high overcurrent event that exceeds the BMS's ability to disconnect. If it blows, that's the fuse doing its job to prevent a much worse outcome. Treat a blown fuse as a diagnostic event. While it's possible to replace, first identify and correct the root cause (wiring fault, short circuit, or failed component) before replacing the fuse and using the battery. Do not simply replace the fuse and re-energize without investigation.

The V2-T fits a Group 8D footprint at 20.86×8.65×12.06 inches and is designed as a direct physical replacement for Group 8D battery trays and compartments. At 97lbs, it's roughly half the weight of a comparable AGM Group 8D, and it delivers substantially more usable energy. Lead-acid batteries typically provide only 50% usable capacity before voltage drops below useful levels, meaning a 460Ah AGM realistically delivers around 230Ah. The Epoch delivers up to 460Ah. One V2-T can realistically replace two or more AGM Group 8D batteries while taking up less space and lasting significantly longer.
