5.89kWh of heated, Bluetooth-connected lithium in one 8D-size battery. The Epoch 12V 460Ah Essential Series stores 5.89kWh in a BCI Group 8D footprint, more energy than four 100Ah batteries under a single BMS. Automatic internal heating lets it charge in winter, and built-in Bluetooth with a shunt shows your exact state of charge on your phone. It's built for RV, marine, off-grid solar and backup systems that need a large house bank without a rack of batteries.

🔧 Will It Fit & Work for You?

A BCI Group 8D footprint, the large size used in many coaches, boats and solar banks. Popular uses include:

  • Motorhome & fifth wheel house power
  • Marine house power & yachts
  • Off-grid solar & inverter systems
  • Cabins & tiny homes
  • Home backup power
  • Work trucks & mobile power
  • 24V–48V systems (in series)
📏 Quick check before you order:
  • Your space fits 20.55" L × 9.45" W × 8.60" H (8D), plus room for terminal hardware, cable bends and service access.
  • Your mounting can handle 84 lb. Plan a two-person lift.
  • Your inverter's DC input stays within 200A continuous (about 2,560W, which commonly suits 2,000–2,400W inverters), with 138A recommended for sustained loads.
  • Your charger has a LiFePO4 profile and supplies at least 0.5A so the heater can run in the cold.
  • It's a deep-cycle battery, not for starting engines. Add a properly sized fuse or breaker near the positive terminal.

Why It's the Big-Bank Upgrade

⚡

A Whole Bank in One Box

5.89kWh, more than four 100Ah batteries, under one BMS. Fewer cables, fewer connections and no balancing between batteries.

🔥

Winter-Ready Charging

Below freezing, charging current powers internal heaters (never your stored energy). Tested to -20°C and rated for ambient temperatures down to -40°C.

📱

Bluetooth With a Built-In Shunt

The free Epoch Li-Ion app shows state of charge, voltage, current and temperature, with no separate monitor to buy.

🔌

Runs a Real Inverter

200A continuous (about 2,560W) supports common 2,000–2,400W 12V inverters with proper cabling and fusing, and 400A peaks for up to 10 seconds.

🔁

Scales Up

Up to 4 in series for 24V–48V, or up to 4 in parallel for 1,840Ah at 12V, using matched batteries.

🧰

Zero Maintenance

No watering, no acid, no terminal cleaning. Rated for 4,000+ cycles.

⏱️ How Long Will It Run?

Constant load Estimated runtime
100W About 47.1 hours
250W About 18.8 hours
500W About 9.4 hours
10A DC load About 36.8 hours

Epoch planning estimates per battery, based on 80% of nominal energy (about 4,710Wh, 368Ah). Real runtime varies with load, inverter efficiency, cabling, temperature and battery age.

Weight 84 lb Many times heavier
Usable capacity Most of the rated 460Ah About half, to protect battery life
Cold-weather charging Built-in heater Slow & inefficient
Phone monitoring Yes, with built-in shunt No
Warranty 11-year limited Usually 1–2 years

🔌 Charging Made Simple

🔋

Recommended: 138A

Charge at 138A (0.3C) for best results (200A max). Settings for other chargers are in the spec table.

🚫

No Lead-Acid Modes

Use a charger with a LiFePO4 profile. Turn off equalization, desulfation and "repair" modes, and set temperature compensation to 0.

🔥

Cold-Weather Charging

Below 0°C (32°F), a charger supplying at least 0.5A powers the heater. Charging resumes automatically at 5°C (41°F).

🚐

Charging From an Alternator?

Epoch recommends a DC-to-DC charger programmed for LiFePO4 between your alternator and the battery.

❓ Common Questions

Can this replace a bank of 100Ah batteries?
Yes. It stores 5.89kWh, more than four 100Ah batteries, under one BMS, which simplifies wiring and balancing.
Will it fit where my 8D batteries go?
It uses a BCI Group 8D footprint: 20.55" × 9.45" × 8.60". Check tray, hold-down and terminal clearance, and leave room for cable bends and service access.
What size inverter can it run?
200A at 12.8V is about 2,560W before inverter losses, which commonly suits 2,000–2,400W 12V inverters with proper cabling and fusing. 138A is recommended for sustained loads.
How does the heater work in winter?
Charging is blocked below 0°C (32°F). A charger supplying at least 0.5A powers the heaters with incoming charge current only, and charging resumes at 5°C (41°F).
Does it have Bluetooth?
Yes. Built-in Bluetooth and a shunt send state of charge, voltage, current and temperature to the free Epoch Li-Ion app. The security PIN is printed on the battery lid.
Can I wire them for 24V or 48V?
Yes. Up to 4 in series and 4 in parallel (4S4P max), using matched batteries.
Is it waterproof?
No. It's IP54: dust protected and splash resistant. Don't submerge or pressure-wash it.
Can it start my engine?
No. It's a deep-cycle battery. Use a cranking or dual-purpose battery for starting.
