Abyss Battery

Abyss Battery®: Engineered for the Open Water

Founded in 2020 and headquartered in Largo, Florida, Abyss Battery® has quickly established itself as a serious force in the marine power industry. Lithium marine batteries are at the heart of what Abyss does — but the brand's ambitions go far beyond a single product. From professional anglers and recreational boaters to OEM boat builders and off-grid adventurers, Abyss Battery® engineers complete power ecosystems designed to keep people on the water longer, safer, and with less worry about what's under the hull.

Grade-A LiFePO₄ Technology Built for Harsh Conditions

Every Abyss Battery® product is built around Grade-A lithium iron phosphate (LiFePO₄) cells — a chemistry prized for its thermal stability, long cycle life, and consistent voltage output under load. The company's manufacturing process is certified by TÜV Rheinland for functional safety, covering the kinds of real-world marine stresses — vibration, impact, water ingress, and salt spray corrosion — that destroy lesser batteries over time. Internal cell holders physically separate each cell to reduce the risk of short circuits caused by vibration or impact, a construction detail that sets Abyss apart from many competitors.

All batteries in the Abyss lineup — spanning 12V, 24V, 36V, 48V, and 72V configurations — are backed by a 5-year free replacement warranty covering manufacturing defects, with an optional extended warranty program for added long-term protection.

A Complete Marine Power Ecosystem

What distinguishes Abyss Battery® from single-product battery brands is the depth of its ecosystem. Their marine battery chargers are purpose-matched to specific battery models and voltage configurations, ensuring optimal charge curves and extended cell life. For anglers who fish deep water, Abyss's electric fishing reel connectors and batteries plug directly into leading electric reel brands — including Daiwa, Shimano, Seaborg, and Banax — eliminating the tangle of extra wires on a busy boat deck. The lineup also extends to marine power inverters for on-board AC power needs, rounding out a system capable of running everything from electronics to lighting offshore.

To protect these investments, Abyss also offers purpose-built marine battery boxes and trays constructed from marine-grade starboard material — a high-density polyethylene that resists UV exposure, acids, oils, and impact even at extreme temperatures.

Built-In Intelligence: Bluetooth Monitoring

Several Abyss Battery® models feature an integrated Bluetooth battery management system (BMS), allowing users to monitor charge state, cell health, and real-time performance data directly from a smartphone. This kind of onboard intelligence is increasingly standard in premium marine lithium batteries, and Abyss was an early adopter, making it a natural fit for tech-forward anglers who want to know exactly how much run time they have left before heading to a distant waypoint.

Trusted by Dealers, Anglers, and OEMs

In just a few years since launch, Abyss Battery® has earned placement at major marine retailers and has built a growing network of authorized dealers across the United States. Their flagship INFINITE™ SERIES and the innovative SEAL™ battery — which features integrated fire suppression technology — signal a brand that is actively pushing the boundaries of what a marine battery can be, not simply keeping pace with the market.
