24V 314Ah Marine Battery

Product Overview

The 24V 314Ah marine battery delivers 8038Wh of usable energy with over 6000 deep cycles at 80% DOD. In real applications, that means dramatically longer runtime for trolling motors and fewer replacements over a vessel’s lifetime.

Compared with traditional lead-acid systems, this marine lithium battery reduces weight by more than 40% while maintaining stable discharge curves. Voltage sag is minimized, which is critical for fish finders, GPS modules, sonar systems, and autopilot controls.

As part of our advanced marine lithium battery (internal link) solutions, this model integrates seamlessly into larger marine energy storage system architectures.
