Product Summary
The Epoch V2-T Elite 24V 230Ah has its own 300A Class T fuse under a service cover on the lid, so fault protection starts at the battery's outlet. Around it sits the V2 Elite platform: CAN bus to a Victron GX device, an IP67 case, self-heating, Bluetooth monitoring and banks of up to 16 in parallel or two in series.
Specifications:
- 25.6V nominal, 230Ah and 5.89kWh (5,888Wh) from eight prismatic LiFePO4 cells in series (8S1P)
- Built-in JJN-300 Class T fuse, 300A, with a 20kA interrupting rating at 160Vdc, user-serviceable
- 115A continuous discharge and charge, 250A peak discharge for 5 seconds, 180A charge for 5 seconds
- CAN bus at 500 kbit/s to Victron GX devices with DVCC, plus Bluetooth through the included gauge and Epoch Cloud app
- 153.6W heater warms the cells during charging, switching on at 41°F (5°C) and off at 50°F (10°C)
- IP67 PC/ABS case (UL94 V-0), dust-tight and rated for temporary immersion to 3.3 ft (1 m) for 30 minutes
- Up to 16 in parallel (3,680Ah) or two in series (51.2V nominal), with 3,500+ cycles to 70% capacity at 77°F (25°C)

About the Epoch V2-T Elite 24V 230Ah Battery
A 5.89kWh lithium battery can push a huge current into a short circuit. Class T fuses are the type built to interrupt it. The V2-T puts one inside the battery: a 300A JJN-300 with a 20kA interrupting rating at 160Vdc. It sits behind a protected service cover on the lid. Epoch designed it to cut fault energy at the battery's outlet, and it works alongside your main disconnect and branch protection.
Around the fuse sits the V2 Elite platform. Connect the included harness to a Victron Cerbo GX MK2, turn on DVCC, and select Epoch as the controlling BMS and battery monitor. The battery then sets charge voltage and current for every Victron charger on the system. The IP67 case, 153.6W heater and included Bluetooth gauge suit boats, RV basement bays and unheated cabins.
V2-T vs V2 Elite vs Essentials: Choosing an Epoch 24V 230Ah Battery
All three hold 5.89kWh at 25.6V. The V2-T is the one with Class-T protection built into every battery. It also has the higher continuous rating of the two Elite models, at 115A (110A on the V2 Elite). Choose it for boats and RVs where you want each battery's outlet protected at the case. It suits multi-battery banks too, where every unit should bring its own Class T fuse.
Does your design already land each battery on its own Class-T fuse, say through a Victron Lynx Class-T Power In? Then the V2 Elite 24V 230Ah gives you the same Victron integration, IP67 case and 16-battery parallel limit for less. The Essentials 24V 230Ah is the low-profile choice. It has a Group 8D case 8.6 inches tall, 200A continuous, Bluetooth only, IP54 and parallel banks only. Both Elite models carry free repair or replacement for the first five years of the 11-year warranty. The Essentials includes free replacement in years 1 to 3.
Replacing the Built-In Class T Fuse
If a fault opens the fuse, you swap the fuse, not the battery. Epoch strongly recommends qualified service for the replacement. First, switch off every charger and load, open the disconnect, and find and fix the fault. Then clean the contacts and fit the exact approved part (JJN-300). Torque it to 106 in-lb (12 N·m) and refit every cover.
Victron Setup and DIP Switches for Parallel and 48V Banks
The grey RJ45 lead from the harness plugs into the GX device's BMS-CAN port. On a Cerbo GX Mk2, use VE.Can 1 or 2 set to 500 kbit/s. Extra batteries daisy-chain from each black port to the next battery's blue port. Don't add branches or tees anywhere on the communication line. Eight DIP switches on each battery mark the primary unit, the last unit and every position in between.
Banks grow to 16 in parallel (3,680Ah, 94.21kWh) or two in series (51.2V nominal, 58.0V full). Use identical batteries of the same age, capacity and state of charge. The V2-T DIP Switch Guide lists the setting for every position. Plan the bank as either parallel or series, since mixed series-parallel isn't supported.
Installing the V2-T: External Fusing, Cables and Mounting
Epoch still calls for a DC-rated fuse or breaker in the positive cable, as close to the battery as practical. Size it at 125 to 150 percent of your maximum operating current, and never above the cable's ampacity. It needs a voltage rating of at least 29.0V (58V for a two-battery series string). Add a disconnect rated for full system current, then protect each branch circuit. A Victron Lynx Distributor puts fused MEGA outputs right on the busbar.
Run equal-length cables to every battery in a parallel bank. Our custom battery and inverter cables are made to order from 6 AWG to 4/0 AWG, so each run matches. Torque the M8 terminal bolts to 106 in-lb (12 N·m).
At 98.9 lb, plan on two people or a lifting aid. Set it upright on a flat, rigid surface where you can reach the terminals, fuse cover, switch and communication ports. Secure it against vibration and wave impact. Threaded inserts take the Epoch V2 Elite mounting hardware (8D bracket, sold separately). Replacing a Group 8D lead-acid battery? Check tray, hold-down and lid clearance against the 12.06 in height first.
Our team is happy to help with sizing the bank, fusing and cables for your system.

Frequently Asked Questions
No single component makes an installation compliant. ABYC compliance covers the complete system: disconnects, overcurrent protection, conductors, securement, grounding and commissioning. The V2-T's Class T fuse protects the battery outlet. The rest of the design still has to meet the standard.
Use a lithium (LiFePO4) CC/CV profile. Hold absorption at 28.4V for 15 minutes per battery in the bank, and set float at 27.0V. Turn off equalization and temperature compensation. Never charge above 29.0V.
With DVCC on, the battery sets these limits on Victron chargers. Epoch still asks you to program every charge source to the same values, so charging stays safe if CAN communication is lost.
One battery is rated 115A continuous, about 2,944W of DC power at 25.6V before inverter losses. A 2,000W load through a 90 percent efficient inverter draws about 87A. If your inverter's continuous DC draw can go over 115A, add batteries in parallel.
Yes, through a DC-DC charger or an alternator regulator set up for lithium. Epoch points out that a large lithium bank can draw more current than an alternator is built to deliver continuously. On a boat or vehicle with a 12V engine, a DC-DC charger with a 12V input and 24V output handles the voltage step. It also limits the current.
Epoch plans on about 4,710Wh of usable energy (80 percent of capacity). That's about 7.4 hours at a steady 25A DC load, about 3.7 hours at 50A, and about 1.6 hours at the full 115A.
