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.

Frequently asked questions Epoch 24V 230Ah V2-T Elite Battery FAQs Common questions about the Class-T fuse, Victron setup, heating, IP67 protection, inverter sizing, and bank expansion. 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.
