ABYSS® 36V 75Ah Lithium Trolling Motor Battery

It is designed for compatible 36V trolling motors and has a nominal voltage of 38.4V. 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® 36V 75Ah battery can replace three 12V lead-acid or AGM batteries connected in series for a compatible 36V 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 75Ah by average battery current to make an initial runtime estimate. At an average 20A draw, the theoretical result is 3.75 hours before allowing for reserve, usable capacity and operating conditions. Wind, current, speed and boat load change actual runtime. This 75Ah model has 25% more nominal capacity than the 36V 60Ah, with a longer Group 49 case to account for when planning the installation.

Use an ABYSS-approved 36V 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 three separate 12V batteries should not be assumed compatible with one 36V battery; have its model and settings checked before reuse.

Yes, through compatible DC-DC charging equipment. The ABYSS® 36V High Output DC-DC Alternator Charger is optimized for the 36V 75Ah and 105Ah trolling batteries. Have your installer match the charger to the engine's available alternator output, starting battery and wiring. Energy recovered depends on running time and charging conditions, so plan shore charging around actual use.

The 36V 75Ah Bluetooth model supports monitoring through the ABYSS Battery app on a compatible Apple or Android phone within Bluetooth range. You can check charge status and operating information such as voltage, current and temperature. If your installation calls for a helm display, ask ABYSS to confirm a supported integration before specifying network equipment.

The Group 49 battery measures 19.10 × 6.70 × 9.45 inches and weighs approximately 43.06 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 36V 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.
