Lithium vs Lead-Acid Trolling Motor Batteries: Why the ABYSS 36V Kit Wins

Lithium vs Lead-Acid Trolling Motor Batteries: Why the ABYSS 36V Kit Wins

If you're running a 36V trolling motor, you already know the pain of managing three 12V lead-acid batteries. They're heavy, they lose capacity as they discharge, and they need constant maintenance. Lithium battery technology has changed the game — and the ABYSS 36V Lithium Trolling Motor Battery is built specifically for anglers who want more time on the water and less time worrying about power.

Here's a straight comparison so you can decide for yourself.

Weight: The Difference You Feel Every Trip

A typical 12V 100Ah lead-acid battery weighs around 60–65 lbs. Run three of them for a 36V system and you're adding nearly 200 lbs to your boat before you even leave the dock.

The ABYSS 36V kit consolidates that into a single lithium unit at a fraction of the weight. Less weight means better boat performance, improved fuel efficiency on your outboard, and a lot less back strain loading and unloading.

Runtime: Lithium Delivers More Usable Power

Lead-acid batteries are rated at full capacity, but there's a catch — you can only safely use about 50% of that capacity before you risk damaging the battery and shortening its life. That means a 100Ah lead-acid battery gives you roughly 50Ah of usable power.

Lithium batteries like the ABYSS deliver close to 100% of their rated capacity. The ABYSS 36V 60Ah kit gives you more usable energy than a comparable lead-acid setup — and it maintains consistent voltage throughout the discharge cycle, so your trolling motor runs at full power until the battery is nearly depleted, not just at the start of the day.

Lifespan: Do the Math

Lead-acid batteries typically last 2–4 seasons with proper care. Lithium batteries are rated for 2,000+ charge cycles — that's potentially 10+ years of use.

When you factor in the cost of replacing three lead-acid batteries every few years, the ABYSS kit pays for itself. It's not just a battery — it's a long-term investment in your fishing setup.

Charging: Simpler and Faster

The ABYSS 36V kit includes a 10A onboard charger, so there's no need to manage three separate chargers or worry about balancing charge levels across multiple batteries. Plug in one cable, walk away, and come back to a fully charged system ready for the next trip.

Compatibility: Built for Your Trolling Motor

The ABYSS 36V 60Ah kit is designed as a direct replacement for three 12V lead-acid batteries in series. It's compatible with 36V trolling motors including Minn Kota, Garmin Force, Power-Pole MOVE, and Rhodan Gen5 — the same motors we carry at Captain Mason Yacht Services.

The Bottom Line

If you're still running lead-acid batteries on your 36V trolling motor, you're leaving performance on the table and hauling unnecessary weight. The ABYSS 36V Lithium Kit is lighter, lasts longer, delivers more usable power, and simplifies your charging setup.

It's the last trolling motor battery you'll need to buy. Browse our full Trolling Motor Batteries & Accessories collection to see all options.
