12V 150AH Marine Batteries

Product Overview

The 12V 150Ah marine battery is engineered for demanding marine environments where reliability, safety, and long service life are critical. Designed with advanced LiFePO4 chemistry, this battery delivers stable 12.8V output and 1920Wh usable energy, making it ideal for fishing boats, yachts, trolling motors, and navigation systems.

Compared to traditional lead-acid alternatives, this marine lithium battery provides over 4000 cycles at optimal depth of discharge. As a result, fleet operators and marine OEM partners benefit from significantly lower lifecycle costs and reduced maintenance.

Built with IP65 waterproof protection and an intelligent BMS, the battery ensures consistent power delivery even in humid, saltwater, and offshore conditions. For buyers comparing different marine battery technologies, our complete Marine Batteries portfolio offers scalable configurations for various vessel types.
