Keep Fishing Longer With Intelligent On-The-Go Charging

The ABYSS 36V High Output Alternator Charger is engineered for anglers who demand maximum runtime and faster battery recovery on the water. Designed specifically for modern high-capacity lithium trolling motor systems, this advanced DC charging solution allows your 36V ABYSS battery bank to recharge directly from your outboard engine while underway.

Whether you are running offshore, chasing tournaments, or spending long days on the lake, the ABYSS High Output Alternator Charger helps maximize your time on the water by converting engine-generated power into clean, efficient lithium charging energy.

Built for the next generation of marine power systems, this charger is optimized for ABYSS 36V 75Ah and 36V 105Ah trolling motor batteries, delivering the performance needed to support larger capacity lithium platforms without relying solely on shore power.

Engineered For High-Capacity Lithium Systems

Traditional charging solutions were not designed for today's high-performance trolling motor setups. The ABYSS 36V High Output Alternator Charger bridges the gap between your outboard engine and lithium battery system, providing intelligent charging management that keeps your trolling motor battery ready for action.

With advanced CC/CV lithium charging technology, the charger automatically manages charging stages to safely deliver power while protecting battery health and extending service life.

Key Features:

High Output 36V Lithium Charging - Designed for larger capacity 36V trolling motor batteries, including ABYSS 36V 75Ah and 36V 105Ah models.

Optimized For LiFePO₄ Marine Batteries - Specifically engineered for lithium iron phosphate battery chemistry with proper charging voltage profiles and intelligent charge management.

Charge While You Run - Convert available alternator power from your outboard engine into usable energy for your trolling motor battery system, extending your fishing time between shore charges.

 Intelligent Charging Technology - Utilizes constant current (CC) and constant voltage (CV) charging stages to maximize charging efficiency while protecting lithium battery performance.

Marine-Ready Construction - Built with a waterproof, dust-resistant, and shock-resistant design to withstand demanding marine environments.

High Efficiency Performance - Up to 94.4% power efficiency helps maximize available alternator output while minimizing energy loss.

Advanced Protection Systems:

  • Short circuit protection

  • Over-voltage protection

  • Under-voltage protection

  • Over-current protection

  • Over-temperature protection

Perfect Pairings Best For:

- ABYSS 36V 105Ah Lithium Trolling Motor Battery
- ABYSS 36V 75Ah Lithium Trolling Motor Battery
- Tournament Bass Boats
- High-performance fishing boats
- Long-range offshore trolling applications

Why Choose ABYSS High Output DC Charger?

Your trolling motor is only as powerful as the energy behind it. The ABYSS 36V High Output Alternator Charger was designed for anglers who refuse to cut their day short because of battery limitations.

More runtime. Faster recovery. Smarter charging.

Built for the industry. Built for anglers who demand more.
