Abyss Battery Battery Chargers

Abyss Battery Marine Chargers: Engineered for Life on the Water

When you invest in a premium lithium marine battery system, the charger you pair it with is just as critical as the battery itself. Abyss Battery has built a reputation as one of the most innovative names in marine power — and their lineup of battery chargers reflects that same commitment to precision engineering, rugged durability, and intelligent technology.

A Charger for Every Setup

Abyss Battery offers a broad range of on-board marine chargers to fit virtually any configuration on the water. Their lineup spans from dedicated single-voltage units to sophisticated multi-bank solutions. With 3- and 4-bank charging capability, their multi-bank units can simultaneously charge and maintain batteries of various voltages and chemistries — including Lithium, AGM, and Lead-Acid. This means tournament anglers and weekend cruisers alike can replace a tangle of separate chargers with a single, streamlined device.

For boaters who want to top off their trolling motor battery while running between spots, Abyss Battery offers their On-Board DC-DC Alternator Charger series in 24V and 36V variants. This system harnesses the energy produced by your boat's alternator, transforming it into usable power for 24V or 36V trolling motor batteries. With state-of-the-art technology, the ABYSS® On-Board Alternator Charger applies 10A of on-demand charging voltage to your 36V battery so it only receives the charging current it needs to replace energy that has been consumed.

At the top of the Abyss charger lineup sits the SHARK™ Bi-Directional DC-DC Charger. This intelligent booster charger seamlessly converts 12V power from your outboard engine to charge your 36V lithium trolling motor battery — and it works in reverse too, sending 36V back to maintain your 12V house battery. Its dual-function design allows you to eliminate having an extra house battery or downsize its capacity, saving weight, cost, and installation space without compromising performance.

Built to Survive the Marine Environment

Every Abyss Battery charger is engineered with the harshest conditions in mind. Their chargers boast a robust, shock-resistant, and vibration-resistant construction — fully waterproof with an IP68 rating for complete protection against water ingress — and have been rigorously saltwater tested to guarantee resistance to corrosion. Innovative LED lights provide real-time monitoring of connection, power status, and state of charge, keeping you informed and in control.

Abyss Marine Chargers deliver 99% charge efficiency, consistent power, and superior voltage stability. For boaters who demand the best for their LiFePO4 investment, that level of precision matters — protecting cell chemistry and extending the usable life of the battery over hundreds of charge cycles.

Safety and Compliance Standards

Abyss Battery is proud that their marine battery chargers meet industry-leading safety and compliance standards, including ABYC certification and field-tested reliability — engineered with advanced features like ignition protection and a lithium pulse wake-up mode for smarter, more efficient charging. These aren't afterthoughts; they're the result of a brand that prioritizes safety at every level of product design.

Part of a Complete Power Ecosystem

Abyss Battery chargers are designed to integrate seamlessly into the broader Abyss ecosystem. Each INFINITE Series™ system includes a high-performance SEAL® lithium battery, a CRYSTAL® X3 Battery Monitor, and the SHARK® Bi-Directional DC Charger — creating a complete marine-grade energy ecosystem that's lightweight, long-lasting, and intelligent. Whether you're outfitting a bass boat for tournament season or a center console for offshore runs, Abyss Battery delivers a charger solution that keeps you powered, protected, and ready to go.
