A 5.89kWh Energy Vault for Marine and Off-Grid Systems
Premium 24V storage with source protection, managed communications, and scalable architecture.
The V2-T platform is intended for deep-cycle house-power and energy-storage service rather than engine starting. One battery provides 230Ah at 25.6V nominal and supports large 24V loads without the complexity of wiring several smaller batteries in parallel.
The integrated fuse, CAN communication, remote gauge, external power control, heating, and Bluetooth monitoring reduce installation clutter—but installers must still provide the main disconnect, properly selected downstream overcurrent protection, branch fusing, busbars, conductors, securement, precharge where required, and a complete commissioning plan.
Safety: The V2-T Class T Fuse
High-interrupt source protection, managed BMS safeguards, and a sealed serviceable enclosure.
User-Serviceable 300A Class-T Fuse
The Eaton Bussmann JJN-300 has a 20kA interrupting rating at 160V DC and sits under a protected service cover on the lid. It reduces fault energy at the battery outlet, but it does not replace the main disconnect or downstream cable and branch protection: install a DC-rated fuse or breaker in the positive conductor, as close to the battery as practical.
Advanced BMS and Published Safety Listings
The embedded BMS supervises cell voltage, current, temperature, protection events, and balancing. Epoch publishes UL1642, UL9540A, and IEC 62619:2022 cell references, plus CE, RoHS, and fuse-related listing information.
IP67 Dust-Tight, Immersion-Rated Enclosure
The enclosure is dust-tight and rated for temporary immersion up to 1 meter for up to 30 minutes when every seal and gland is correctly installed. Treat IP67 as an ingress-protection test rating—not permission for permanent submersion, standing-water installation, water jets or pressure washing. Install the battery where it stays dry in normal use.
Premium Smart Features and Seamless Integration
Managed Victron charging, cold-weather operation, and real-time battery visibility.
Native Victron Integration via CANBus
The BMS communicates at 500kbit/s through the specified battery harness. A correctly configured Cerbo GX or Ekrano GX can use Epoch as the controlling BMS and battery monitor with DVCC enabled, allowing the battery to publish managed operating data and charging limits to the Victron system.
Cold-Weather Ready with Internal Heating
The 153.6W heater is controlled by the BMS. The cells are not charged below 0°C (32°F); while charging, the heater switches on at 5°C (41°F) and off at 10°C (50°F), using incoming charge energy to warm the cells before normal charging proceeds.
Bluetooth App and Physical Monitoring
Monitor state of charge, cell voltage, temperature, charge and discharge cycles and system health alerts in the Epoch Cloud app (iOS and Android), over Bluetooth 4.0 through the included battery gauge. The included remote digital gauge and external power button provide local access without opening the battery compartment.
Unrelenting Power and Massive Scalability
High-capacity standalone power with supported series or parallel expansion.
A single battery supports 115A continuous discharge (about 2,944W DC before inverter losses) and 250A for 5 seconds. Size inverters by their DC input current: a 2,000W load through a 90%-efficient inverter draws about 87A. If an inverter's continuous DC input can exceed 115A, add batteries in parallel. Uses include marine hotel loads, 24V trolling-motor and electric auxiliary systems where requirements match, and off-grid loads.
Scale to sixteen batteries in parallel for 3,680Ah and about 94.21kWh at 25.6V nominal, or use up to two matched batteries in series for a 51.2V nominal (48V-class) string, 58.0V at full charge. Mixed series-parallel banks are not supported.
Deep-cycle and installation boundary
This battery is for house-power and energy-storage service, not engine cranking. The Class-T fuse is a source-protection feature, not a complete electrical system. Qualified installers must design the disconnect, downstream protection, branch circuits, conductors, mounting, charging, monitoring, and documentation.

Marine and ABYC installation note
A built-in Class-T fuse supports system safety—but compliance applies to the complete installation.
Installers searching for an ABYC-compliant marine battery system should evaluate the full design rather than the battery alone. Disconnect accessibility, source and branch protection, unfused conductor length, cable ampacity, securement, ignition-protection requirements, grounding, labeling, compartment conditions, and commissioning must all be addressed under the applicable standards and vessel design.
Installation and commissioning note
Secure the battery first, then engineer conductors, protection, precharge, charging, communications, and documentation.
Install on a flat rigid surface with service access to terminals, the fuse area, switch, and communication ports. Use approved restraints, short protected source conductors, appropriate busbars and lugs, controlled precharge for large capacitive loads, and equal-length conductors in parallel banks. Commission Victron communications, DIP settings, current limits, charging voltages, alarms, and module counts before placing loads into service.

What Can It Run?
Planning estimates for a single 5.89kWh battery, using 80% of nominal energy (about 4,710 Wh).
| Load |
Estimated Run Time |
| 2,944W DC Load |
≈ 1.6 Hours (4,710 Wh ÷ 2,944 W) |
| 1,000W DC Load |
≈ 4.7 Hours (4,710 Wh ÷ 1,000 W) |
| 500W DC Load |
≈ 9.4 Hours (4,710 Wh ÷ 500 W) |
| 100W DC Load |
≈ 47 Hours (4,710 Wh ÷ 100 W) |
Estimates are for a constant DC load at the battery terminals and use 80% of nominal energy, a planning figure that leaves reserve for battery life and cold conditions. Inverter losses, cable losses and temperature reduce runtime.

Recommended Charging Settings
Program every charge source, Victron equipment included, to these settings:
- Charger type: Lithium (LiFePO4) compatible, CC/CV
- Bulk/absorption voltage: 28.4V
- Absorption time: 15 minutes per battery in the bank (for example, 60 minutes for four batteries)
- Float voltage: 27.0V
- Equalization: Disabled
- Temperature compensation: Disabled (0 mV/°C)
- Maximum continuous charge current: 115A per battery, for all charge sources combined; up to 180A for 5 seconds (the BMS charge over-current protection acts at 180A after a 5-second delay)
- Never charge above 29.0V. Do not use lead-acid equalization, desulfation or repair modes.
- Charge temperature: 0°C to 50°C (32°F to 122°F), with heating support. The cells are not charged below 0°C (32°F); while charging, the 153.6W heater switches on at 5°C (41°F) and off at 10°C (50°F), using incoming charge energy, so the charge source must supply enough current for heating and charging.
- Alternators: use a DC-DC charger or an alternator regulator set up for lithium.
To use the V2-T Elite with Victron systems
- Install and wire the batteries with all chargers and loads off, and set the DIP switches on every battery (see the manual).
- Fit the harness plug with the waterproof bung into the Master battery's blue port.
- For a bank, run an RJ45 cable from the Master's black port to Slave 1's blue port, then from Slave 1's black port to Slave 2's blue port, and so on, up to 16 batteries in parallel. Daisy-chain only; never use branch or tee connections.
- Plug the harness's grey RJ45 plug into the GX device's BMS-CAN port (Cerbo GX or Ekrano GX). On a Cerbo GX Mk2, use VE.Can 1 or VE.Can 2 and set the port speed to 500 kbit/s under Settings › Services › VE.Can.
- Switch on the batteries.
- On the GX device, turn on DVCC, set the controlling BMS to Epoch and set the battery monitor to Epoch.
- To confirm proper reporting, check that the Epoch battery appears in the GX device list. Under the battery's Details, the number of modules online equals the number of batteries installed, and the installed capacity equals the bank capacity (for example, 920Ah for four batteries).
- While charging (not while inverting), the inverter tile shows External control. Under DVCC the system charges to 28.4V, holds absorption for at least about 15 minutes per battery, then floats at 27.0V.
- Manually program the MultiPlus, Quattro and every other charge source to the values above, so charging stays safe if CAN communication is lost.

What does “V2-T” mean, and why is the Class-T fuse important?
The V2-T design adds a user-serviceable 300A Eaton Class T fuse to the V2 Elite platform. The C24230A-A uses an Eaton Bussmann JJN-300 rated at 300A with a 20kA interrupting rating at 160V DC, under a protected service cover on the lid. It reduces fault energy at the battery outlet, but it does not replace the main disconnect, downstream conductor protection, branch fusing, or the rest of a code-compliant system design.
If the internal Class-T fuse opens, is the battery ruined?
No. The fuse is replaceable through the protected service-access area. Isolate every source and load, open the main disconnect, verify the system is de-energized, identify and correct the fault, and replace the fuse only with the exact approved model and rating. Restore all covers and seals before returning the battery to service; qualified service is strongly recommended.
Does the 24V V2-T connect directly to a Victron system?
Yes, when installed with Epoch's specified communication harness and configuration. The battery communicates at 500kbit/s over CAN. Connect the designated grey RJ45 lead to the appropriate BMS-Can or configurable VE.Can port on a compatible Cerbo GX or Ekrano GX, set the port as instructed, enable DVCC, and select Epoch as the controlling BMS and battery monitor. Do not assume every generic RJ45 cable has the required battery-side pinout.
Can I connect these batteries in series or parallel?
The C24230A-A user manual supports up to two batteries in series (51.2V nominal, 58.0V at full charge) or up to sixteen in parallel (3,680Ah). Mixed series-parallel banks are not supported. Use C24230A-A batteries of the same age, capacity and state of charge (fully charge each one on its own first), set the DIP switches for the bank, and follow the manual for the selected topology.
How large can a parallel V2-T battery bank become?
Sixteen 5.888kWh batteries provide about 94.21kWh of nominal stored energy and 3,680Ah at 25.6V nominal. Every battery output is a separate source and requires an engineered connection to common busbars, equal-length conductors, appropriate source and branch protection, secure mounting, communication configuration, and professional commissioning.
How does internal self-heating work in freezing conditions?
The battery includes a 153.6W heater controlled by the BMS. The user manual lists low-temperature charge protection at 0°C, heater activation during charging at 5°C, and heater deactivation at 10°C. Available incoming charge energy warms the cells before normal charging proceeds. Charging equipment must still be programmed correctly and provide enough current for heating and charging.
Is the battery completely waterproof?
No. The enclosure is IP67 rated—dust-tight and tested for temporary immersion up to 1 meter for up to 30 minutes when all seals and glands are correctly installed. It is not rated for water jets, pressure washing or continuous submersion. Install the battery where it stays dry in normal use, and make sure all harness connectors are fully seated.
What size inverter can one 24V 230Ah V2-T battery support?
At 25.6V nominal and 115A continuous discharge, the battery provides approximately 2.94kW of nominal DC output before inverter losses. Inverter DC input current ≈ AC load ÷ (25.6V × inverter efficiency): a 2,000W load through a 90%-efficient inverter draws about 87A. If an inverter's continuous DC input can exceed 115A, add batteries in parallel. Final inverter sizing must account for efficiency, surge demand, cable voltage drop, ambient temperature, precharge requirements, downstream protection, and the battery's current limits.
Does the built-in fuse make the installation ABYC compliant?
No single component makes an entire installation ABYC compliant. The integrated Class T fuse reduces fault energy at the battery outlet but does not replace the main fuse, disconnect or branch protection; compliance depends on the complete system—including disconnect location, unfused conductor length, conductor ampacity, overcurrent protection, ignition-protection requirements where applicable, securement, routing, labeling, grounding, and qualified installation.
What can I monitor through Bluetooth?
The Epoch Cloud app (iOS and Android) shows state of charge, cell voltage, temperature, charge and discharge cycles and system health alerts, over Bluetooth 4.0 through the included battery gauge (stay within about 10 m). The gauge also shows state of charge. In a Victron-managed system, the GX device becomes the central view for battery and system data.
What are the dimensions and weight?
The user manual lists the C24230A-A at 20.86 inches long by 8.65 inches wide by 12.06 inches high, with a weight of 98.9 pounds. It uses M8 terminals with a published terminal torque of 12N·m (8.85lb-ft). Confirm compartment clearance, service access, cable bend radius, and mounting hardware before ordering.

Epoch Batteries Limited Warranty
11-Year Limited Warranty: 5 Years Free Repair or Replacement
- Years 1–5: free repair or replacement (Epoch chooses which)
- Years 6–11: 40% off MSRP on a replacement battery
Epoch Batteries warrants this product to the original end-user purchaser to be free from defects in materials and workmanship under normal use and service for the warranty period above, when it is installed, operated, charged, stored and maintained as its manual describes. The warranty is not transferable and ends if the product is sold or given to someone else.
How the 40% Discount Works
After the free coverage ends and through Year 11, if the battery has a covered defect Epoch offers a new replacement of the same model (or a current Epoch model of equal or greater capacity and function) at 40% off Epoch's MSRP on the date of the offer. The offer covers one replacement per defective battery, bought directly from Epoch, and you pay the discounted price, any tax and shipping.
When Coverage Starts
Coverage starts on the date of your original purchase. To confirm that date, register the product with Epoch within 90 days of purchase or keep your proof of purchase (an invoice or receipt showing the product, purchase date and seller). If you can provide neither, coverage starts on the manufacturing date recorded for the product's serial number. A repaired or replacement product is covered for the rest of the original warranty period.
What Is Not Covered
The warranty covers defects in materials and workmanship only. It does not cover damage or failure caused by installation, wiring or system design that doesn't follow the manual (including undersized or damaged cables, poor crimps, loose or corroded connections and incorrect fusing); reverse polarity, short circuits or faults in the connected electrical system; series or parallel connections beyond the manual's limits, or mixing batteries of different models, capacities, ages or states of charge; a product not secured as the manual requires; charging outside the manual's voltage, current or temperature limits; discharge above the rated current, or engine starting with a battery not listed as a starting or dual-purpose battery; over-discharge, storage fully discharged, or storage for more than 3 months without recharging; accidents, impact, fire, flood, power surges, submersion or exposure beyond the product's IP rating; opening, modification or repair by anyone other than Epoch or an Epoch-authorized provider; removed or altered serial numbers; normal capacity loss and wear consistent with age and use; or cosmetic damage that doesn't affect performance. Using chargers and other equipment from other brands does not affect coverage by itself.
Obtaining Warranty Service
Start a claim through the Epoch Warranty Portal before the warranty period ends, with the model, serial number, proof of purchase or registration, a description of the problem and any photos, videos or app screenshots. If the claim qualifies, Epoch issues an RMA number with packing and shipping instructions; do not ship a product without an RMA. Epoch inspects and tests the product, typically within 3–10 business days after it arrives, and then repairs or replaces it, or makes the discount offer where applicable.
Shipping
You pay to ship the battery to Epoch; Epoch pays to ship an approved warranty repair or free replacement back to you. For discount replacements you pay shipping on the replacement battery. Packaging must follow the RMA instructions (lithium batteries are regulated hazardous materials in transport).
