Monster Marine Lithium™ MML-CW24100JB “Goliath”

24V 100Ah Bluetooth Deep Cycle Marine Trolling Battery


Overview

Meet Goliath — the most powerful 24V lithium battery available in a Group 31 footprint.
Engineered for serious anglers and heavy-duty marine setups, this 24V 100Ah Bluetooth Lithium Battery delivers unmatched capacity, long runtime, and exceptional reliability in a compact, drop-in size.

Replacing two traditional 12V marine batteries, Goliath reduces overall system weight while providing the endurance and efficiency needed for long days on the water.
