Founder-Built. Supported for Life.
Abyss was founded in Largo, Florida by a tournament angler who grew up running boats out of Clearwater, and who'd spent over a decade in lithium before building his own line.
The problem was always the same: every marine battery worked fine until the moment it mattered. Abyss closes that gap.
Marine-only lithium, batteries and chargers engineered to run as one system, and the first built-in fire suppression in the category. Founder-built, salt-tested, supported for life.
