Yes. Two 12V batteries wired in series produce 24V. This battery is a single 24V unit that replaces that entire dual-battery bank. Connect it the same way positive terminal to your motor's positive lead, negative to negative without any series wiring between two separate batteries.

In terms of usable capacity: two Group 29 lead-acid batteries typically rated between 90–115Ah give you roughly half that capacity as usable energy when limited to 50% depth of discharge to protect longevity. This LiFePO4 battery provides approximately 184Ah of usable capacity at 80% depth of discharge, with the option to go deeper when needed.

Runtime depends on motor thrust rating, speed setting, vessel weight, current, and wind. One customer running a 24V 80 lb thrust Minn Kota Terrova for 7 continuous hours in mixed conditions current, chop, and flat water reported 75% of charge remaining at the end of the day. This is one customer's experience and results will vary based on conditions.

As a general estimate: a 24V 80 lb thrust motor draws approximately 40–55A at moderate speed and 15–25A at low trolling speed. At 50A average draw, this battery provides approximately 4.5 hours of runtime. At 20A average draw, approximately 11 hours. These are estimates your conditions will determine actual results.

This battery measures 20.9 inches long, 8.7 inches wide, and 12.1 inches tall. It fits a standard Group 8D battery tray or compartment. It will not fit in a Group 27 or Group 31 tray those are smaller.

Measure your compartment before ordering. You need at minimum 21 inches of length, 9 inches of width, and 13 inches of height, plus clearance for terminal connections and cable routing. Mounting brackets are sold separately and should be ordered at the same time as the battery.

Weight is approximately 100 lb. Plan for a two-person installation or use a battery carrier or lifting strap.

The battery includes all required communication cables. Follow this sequence:

• For a single battery: plug the grey RJ45 cable into the battery's BMS CAN port and the other end into the BMS CAN port on your Cerbo GX or Ekrano GX. On a Cerbo GX Mk2, use VE-CAN1 or VE-CAN2 and change the port profile to CAN-bus BMS in the GX settings menu.
• For multiple batteries in parallel: daisy-chain each battery using the RJ45 cables (each battery's black port out connects to the next battery's blue port in). Connect the grey cable from the last battery in the chain to the GX device.
• In the GX device: enable DVCC, set the controlling BMS to Epoch, set the battery monitor to Epoch.
• Confirm setup: the GX device list should show the Epoch battery or bank with the correct module count and total Ah.
• Also program manual fallback parameters into your Multiplus or Quattro: absorption 28.4V, float 27.0V, bulk 29.2V, in case CAN communication is interrupted.

During normal DVCC operation, the inverter tile will display "External Control" this is expected and confirms the BMS is managing charge sources.

Only if your charger can be programmed for LiFePO4 chemistry at 24V. The required settings are: absorption voltage 28.4V, float voltage 27.0V, bulk voltage 29.2V, maximum charge current 230A (115A recommended).

Do not use a charger set to a lead-acid, AGM, or gel profile. Those profiles use different voltage targets that will either overcharge or undercharge a LiFePO4 battery over time. Most modern multi-chemistry marine chargers including models from ProMariner, NOCO Genius, and Victron Energy have a LiFePO4 mode that can be programmed to these parameters.

If your current charger does not support LiFePO4, it will need to be replaced or supplemented with a compatible unit. Contact us for charger recommendations compatible with this battery.

Yes. The internal self-heating system activates automatically when battery temperature drops below 0°C (32°F). The heater warms the cells to a safe level before allowing the BMS to permit charging current. You do not need to manually activate the heater.

The rated charging temperature range with the heater active is -20°C to 55°C (-4°F to 131°F). Without the internal heater as is the case with many standard lithium batteries charging below 0°C causes lithium plating inside the cells, which permanently reduces capacity and cannot be reversed. The integrated heater in this battery prevents that damage.

LiFePO4 (lithium iron phosphate) is considered one of the thermally stable lithium chemistries. Unlike lithium cobalt oxide used in some consumer electronics, LiFePO4 does not enter thermal runaway under normal operating conditions and does not produce flammable hydrogen gas during charging the way flooded lead-acid batteries do.

The IP67-sealed housing prevents moisture ingress in wet environments. The BMS provides overcharge, over-discharge, short circuit, and temperature protection at the cell level.

Follow ABYC marine electrical standards for cable sizing, fusing at the battery terminal, and mechanical securing of the battery against movement. The battery's UL1973 certification supports compliance with marine installation requirements.

Yes. Up to 16 batteries can be connected in parallel at 24V, expanding total bank capacity up to 3,680Ah. Up to 2 batteries can be connected in series to build a 48V system.

For Victron-connected parallel banks: daisy-chain the RJ45 CAN Bus cables between batteries and connect the final grey cable to your GX device. The GX system will display all batteries as a single bank and calculate total Ah automatically.

Do not mix this battery with other brands, chemistries, or different models in the same bank. All batteries in a parallel bank should be the same model, same age, and at the same state of charge before connecting.

The upfront purchase price is higher than a comparable lead-acid setup. However, lead-acid deep-cycle batteries are typically rated for 200–500 cycles before meaningful capacity loss. At one cycle per weekend fishing trip roughly 26 cycles per season a lead-acid bank may need replacement every 2 to 4 years.

This battery is rated for 3,500+ cycles at 80% depth of discharge. At 26 cycles per season, that represents well over a decade of rated cycle life. At one cycle per day in a continuous marine application, it is rated for over 9 years before capacity drops below 80% of original.

Dividing the purchase price by rated cycle life produces a cost-per-cycle that is substantially lower than replacing lead-acid batteries on a regular schedule. The 11-year manufacturer warranty provides additional coverage not available with lead-acid alternatives.

This battery is sold by an authorized dealer. The full 11-year manufacturer warranty covers manufacturing defects from the date of purchase. Accessories chargers, gauges, cables, switches carry a separate 1-year warranty.

The warranty does not cover physical damage from improper installation or handling, damage from charging with non-LiFePO4 profiles, or use outside the specified operating parameters. Keep your original purchase receipt. For complete warranty terms and how to make a claim, see our Warranty Tab.

No ongoing maintenance is required. LiFePO4 batteries do not need watering, equalization charges, or periodic full discharge cycles. The BMS manages cell balancing automatically during normal charge cycles.

For seasonal storage: store the battery at 50–80% state of charge in a location within the storage temperature range of 0°C to 35°C (32°F to 95°F). LiFePO4 self-discharge is approximately 1–3% per month a battery stored at 80% charge before an off-season will retain most of that charge through several months of storage. Avoid storing fully discharged.

The built-in Bluetooth module connects to the Epoch Batteries app available free for iOS and Android. The app displays real-time state of charge (percentage), voltage, current (charge or discharge amperage), and cell temperature. Bluetooth range is approximately 30 feet. No Wi-Fi or cellular connection is required.

The Bluetooth monitoring system operates independently of the CAN Bus Victron integration. Both systems function simultaneously you can view battery data on the Victron GX display and on your phone at the same time.

An external wired battery gauge is also included and can be mounted at the helm or anywhere on the vessel for charge-level visibility without a phone.

For a typical day of fishing, 230Ah provides more capacity than most users will draw in a single outing. Customers consistently report finishing full days on the water with significant charge remaining. Whether this is more than needed depends on your situation.

The practical advantages of the higher capacity are: no concern about running low during a long day, the ability to fish multiple consecutive days without shore power, and a reserve buffer for situations where charging is not available. The tradeoffs are physical size (Group 8D footprint) and approximately 100 lb of weight per battery.

If your battery compartment is smaller than Group 8D or weight is a primary concern, a lower-capacity 24V option may be a better fit. Contact us for guidance on sizing for your specific vessel and use pattern.

No. Lithium batteries of this capacity are classified as Class 9 Dangerous Goods under PI 965 Section IA. Ground shipping only passenger and cargo air freight is not permitted for batteries in this class. 

Cable sizing depends on the maximum current draw of your system and the length of the cable run. As a starting reference for marine installations at full rated discharge current:

• Up to 48 inches of cable run at 230A: 2/0 AWG marine-grade tinned copper cable minimum
• Longer runs or higher sustained current: 3/0 or 4/0 AWG may be appropriate

Install an appropriately rated fuse or circuit breaker as close to the battery positive terminal as practical within 7 inches per ABYC E-11 standards for ungrounded conductors. Suitable overcurrent protection devices include ANL fuses, MRBF terminal fuses, or Class T fuses rated for the expected maximum current.

Use marine-grade tinned copper cable for all battery connections in saltwater environments. Untinned copper corrodes significantly faster in marine conditions. Consult the ABYC E-11 standard or a certified marine electrician for installation specifications specific to your vessel.

The V2 Elite is the current production model. The primary improvement over the V1 is refined handling of high-voltage alarm events in Victron CAN Bus-connected systems the V2 manages these alerts more accurately, reducing false alarms during normal charging cycles that some V1 users experienced in Victron DVCC configurations. The V2 also incorporates general BMS firmware refinements. If you are building or upgrading a Victron-based system, the V2 is the current recommended version.
