ABYSS® 24V 90Ah Lithium Trolling Motor Battery

It is designed for compatible 24V trolling motors and has a nominal voltage of 25.6V. Check your exact motor model, its accepted battery voltage and current requirements. The battery's published continuous-discharge rating is 100A; your dealer or installer should also confirm the motor settings, wiring and circuit protection for the complete installation.

Yes. One ABYSS® 24V 90Ah battery can replace two 12V lead-acid or AGM batteries connected in series for a compatible 24V trolling motor. Have the installer review the charger, cable routing and battery mounting. Identify any 12V accessories supplied from the old bank so their power supply can be addressed during the conversion.

Divide 90Ah by average battery current to make an initial runtime estimate. At an average 20A draw, the theoretical result is 4.5 hours before allowing for reserve, usable capacity and operating conditions. Wind, current, speed and boat load change actual runtime. At the same voltage, 90Ah provides 50% more nominal capacity than the 24V 60Ah model, giving you more reserve for comparable use.

Use an ABYSS-approved 24V lithium charger with the correct charge profile, current rating and pulse wake-up capability. An existing charger is suitable only if it meets this battery's charging requirements. A charger arranged for two separate 12V batteries should not be assumed compatible with one 24V battery; have its model and settings checked before reuse.

Yes, with a compatible ABYSS® 24V On-Board Alternator Charger installed between the starting system and trolling battery. It regulates charging from available engine-generated power. Your installer should check alternator capacity, starting-battery requirements, wiring and protection. Charging gained depends on engine running time and conditions; use AC charging as needed to begin the next trip with sufficient reserve.

The 24V 90Ah Bluetooth model supports ABYSS Battery app monitoring on a compatible Apple or Android phone within Bluetooth range, including charge status, voltage, current and temperature. For NMEA 2000 battery readings at the helm, consider the separate 24V 110Ah NMEA 2000 model and confirm the display's supported data, network and connection requirements before ordering.

The Group 31 battery measures 12.95 × 6.77 × 8.43 inches and weighs approximately 33.91 lb. Measure the actual compartment and allow clearance for cables, terminal protection and service access. Secure the battery with mounting hardware appropriate to the boat and follow the current installation instructions. Confirm the mounting hardware and charging accessories needed for your installation when placing the order.

Confirm the motor's 24V configuration, expected current draw, secure mounting, cable sizing, circuit protection and terminal torque specified for the hardware. Verify the charger settings, charging operation and Bluetooth connection, then check the motor under load. Record the wiring plan, battery serial number and commissioning results, and give the owner the manuals, app demonstration and registration instructions.

For extended storage, isolate connected loads as directed in the battery manual and keep the battery in a dry, protected location. Follow the current model instructions for storage charge level, temperature limits and periodic checks. Before returning to service, inspect the case, mounting and terminals, then verify charge status and normal operation. Keep connections clean and secure.

Purchases from August 1, 2026 qualify for 10-year defect coverage with required registration. Earlier purchases retain their original terms. Register within 90 days with proof of purchase and the battery serial number through the ABYSS website or app. Keep those details available for support and review the current warranty policy for full terms.
