⚡ Monster Marine Lithium™ “Badger”

12V • 30Ah Portable Bluetooth Deep Cycle Lithium Battery

Model: MML-1230B

Overview

Compact, portable, and reliable — meet The Badger, the ultimate lightweight 12V lithium battery built for mobility and performance.
Weighing only 13lbs, this battery is ideal for kayaks, ice fishing bundles, and portable 12V power setups where efficiency and space savings matter most.

Built with advanced Lithium Iron Phosphate (LiFePO₄) technology, The Badger provides twice the power, a fraction of the weight, and four times the lifespan of traditional sealed lead-acid batteries.
With Bluetooth monitoring via the MMLithium App (iOS & Android), you can easily view voltage, charge level, and performance data in real time.

Installation is simple — a true plug-and-play setup. Up to four batteries can be wired in series for higher-voltage systems (24V, 36V, or 48V).
Designed for anglers, outdoorsmen, and mobile power users, The Badger delivers rugged reliability in a compact package.
