A native 48V battery with self-heating, Victron communication and a serviceable Class T fuse. The Epoch 48V 100Ah V2-T Elite Series stores 5,120Wh at 51.2V in one sealed IP67 case, so a 48V system runs on one battery with one BMS instead of a series string of lower-voltage batteries. The "T" stands for its 250A Eaton Class T fuse, mounted behind a sealed top service panel so it can be replaced without opening the case. CAN communication to a Victron GX device, self-heating for cold-weather charging and Bluetooth monitoring through the included gauge make it a fit for 48V off-grid solar, home backup, RV and marine systems.
80A at 51.2V is about 4,096W DC before inverter losses. Epoch allows 250A for up to 10 seconds for surges.
🔧 Will It Fit & Work for You?
A large 8D-class case at 48V (Epoch sells an optional 8D mounting bracket separately). Popular uses include:
- 48V Victron off-grid solar & cabins
- Home backup & energy storage
- 48V RV & motorhome systems
- Marine house power & yachts
- Victron GX & DVCC systems
- Large 48V banks (up to 16 in parallel)
- Your system runs at 48V nominal. This is a 51.2V battery. Series and series-parallel wiring aren't supported, so it won't work in 96V or higher systems.
- Your space fits 20.86" L × 8.65" W × 12.06" H (529.8 × 219.8 × 306.3 mm, height includes terminal posts). Epoch gives no BCI group size, so confirm fit with these dimensions.
- You can handle about 97 lb (44 kg). Plan on two people or a lifting aid, and mount it upright.
- Your inverter's continuous DC draw stays within 80A (about 4,096W at 51.2V before inverter losses), with 250A allowed for up to 10 seconds. For bigger loads, add batteries in parallel.
- For Victron integration you have a Cerbo GX, Ekrano GX or Cerbo GX Mk2. Without one, program every charger with Epoch's LiFePO4 settings.
- You still add a DC-rated fuse or breaker on the positive conductor close to the battery. The internal Class T fuse doesn't replace a main disconnect or downstream protection.
- It's a deep-cycle battery, not for starting engines.
What Makes the V2-T Different
Class T Fuse Built In
The "T" in V2-T is a 250A Eaton Class T fuse (UL 60691) behind a sealed top service panel. Epoch calls protection and serviceability the major difference: after a qualified installer finds and fixes a fault, the fuse can be replaced through the top panel without opening the case.
Native 48V in One Case
16 cells in series (16S1P) under one BMS: 100Ah and 5,120Wh at 51.2V. No string of 12V or 24V batteries to match, balance and cable together.
Talks to Victron
CAN at 500 kbit/s to a Cerbo GX, Ekrano GX or Cerbo GX Mk2. With DVCC on and Epoch set as the controlling BMS and battery monitor, the battery sets the charge voltage and current limits of your Victron chargers.
Charges in the Cold
Cells aren't charged below 0°C (32°F). Instead, the BMS sends incoming charge current to internal heating pads first, then resumes normal charging once the cells are warm. Charging is supported from -30°C (-22°F) ambient when charge current is available.
Bluetooth Gauge Included
The included battery gauge adds Bluetooth for the free Epoch Cloud app, which shows state of charge, voltage, current, temperature, cycles and alerts.
IP67 Sealed Case
Dust-tight and rated for temporary immersion to 1 m for 30 minutes with seals and glands installed. PC/ABS case rated UL94 V-0. Not rated for water jets, pressure washing or continuous submersion.
⏱️ How Long Will It Run?
| Constant load | Estimated runtime |
|---|---|
| 100W | About 41 hours |
| 500W | About 8.2 hours |
| 1,000W | About 4.1 hours |
| 3,000W | About 1.4 hours |
Epoch planning estimates for a single battery based on about 4,096Wh usable (80% of rated energy). Inverter losses, cable losses and temperature reduce real runtime.

Lithium vs. a Lead-Acid Bank
| Epoch 48V 100Ah V2-T | Typical Lead-Acid | |
|---|---|---|
| Batteries for a ~5.1 kWh 48V bank | 1 | Several, wired in series |
| Weight | 97 lb | Many times heavier |
| Usable capacity | Most of the rated 100Ah | About half, to protect battery life |
| Victron GX integration | CAN with DVCC | No |
| Cold-weather charging | Built-in self-heating | Slow & inefficient |
| Warranty | 11-year limited | Usually 1–2 years |
🔌 Charging Made Simple
Up to 80A per Battery
80A continuous from all sources combined (90A for up to 5 seconds). Absorption at 56.8V for at least 15 minutes per battery, float at 54.0V. Never exceed 58.0V.
Victron Does It for You
With DVCC on and Epoch set as the controlling BMS, the battery sets your Victron chargers' limits. Epoch still says to program MultiPlus, Quattro and other charge sources with the same settings as a fallback.
No Lead-Acid Modes
Use a LiFePO4 CC/CV profile. Turn off equalization and set temperature compensation to 0 mV/°C. Before first use, turn the battery on and charge it fully at these settings.
Charging From an Alternator?
Epoch says to charge from an alternator through a DC-to-DC charger, or a lithium-ready alternator regulator set up per the alternator maker's guidance.
