Frequently Asked Questions

Choosing the right battery involves considering your boat’s weight, size, and specific power needs. Each vessel is unique, requiring a tailored approach to find the perfect power solution. Our range of 12V dual-purpose lithium marine batteries are crafted for both high-demand starting and deep-cycle applications, providing versatile power for devices on boats of all sizes, especially those without generators like center consoles.

Think of amp hours (Ah) as the capacity of your boat's fuel tank, but for electrical energy. Higher amp hours mean your boat can run longer on a single charge, ensuring extended enjoyment and reliability on the water. More amp hours = More run time!

Absolutely! Our high-output dual-purpose lithium marine batteries are the ideal choice for powering heavy-load marine devices. They're especially beneficial for boats that require robust energy solutions without the bulk of a generator, such as powering SEAKEEPER systems, Marine Boat Chill Plate Refrigeration, and 360˚ OMNI SONAR. With our 12V batteries, you get efficient, reliable power for both starting and deep-cycle needs. All ABYSS® 12V-Volt Lithium Batteries are approved to be used and exceed the specification requirements for Mercury Marine, Yamaha, Suzuki Marine, and Honda Marine Outboard engines.

For inshore boats ranging from 16'ft to 24'ft, and casual fishing trips of around 4-5 hours, our 24V 60Ah Group 24 battery is perfect for you lifestyle needs. For the avid angler, tournament participant, or fishing guide spending over 6 hours, we recommend our 24V 75Ah Group 31 Battery or 24V 100Ah Group 49 setup. Remember, the higher the amp hours, the longer your run time.

Our 36V60Ah lithium battery is a popular choice, with successful installations on over 150 types of center-console boats, ensuring over 8+ hours of runtime for boats up to 34ft in calm conditions. For larger boats or those needing all-day power in 2'-4' seas, our 36V72Ah or 36V105Ah systems are recommended. We've designed these three tiers to cater to different needs and conditions, ensuring you get the most out of your trolling motor system.

At ABYSS®, we are dedicated to enhancing your marine adventures with our state-of-the-art 12V lithium marine batteries, designed to seamlessly integrate with your existing AGM battery charging system. With a precise voltage requirement of 14.4V-14.6V, transitioning to lithium power has never been easier or more convenient. We also have our own selection of 12V On-Board Marine Chargers to meet your needs.

Charging Solutions for 24V and 36V Trolling Motor Batteries:

For those navigating with our robust 24V battery systems, we offer tailored charging solutions to match your energy needs. Choose from our efficient 24V 10A charger, perfectly suited for our 24V 60Ah and 24V 75Ah batteries, or upgrade to the more powerful 24V 20A charger, designed specifically for our 24V 100Ah battery. These options ensure your battery is charged quickly and ready for your next adventure.

Similarly, our 36V lithium trolling motor batteries benefit from specialized charging options. The 36V 10A charger is ideal for our 36V 60Ah and 72Ah batteries, while the more robust 36V 20A charger is crafted for the demanding energy needs of our 36V 105Ah battery.
