Monster Marine Lithium | 12v 100Ah Bluetooth Deep Cycle Lithium Marine Battery Group 31
Overview
Need a lightweight, high-performance battery for your 12V electronics or trolling motor? This is the perfect solution! Weighing only 24 lbs, it not only frees up space but also reduces weight by nearly 60%!
Designed to fit seamlessly into a Group 31 case, the MML-12100B is built with advanced Lithium Iron Phosphate (LiFePO4) technology, delivering twice the power, a fraction of the weight, and a lifespan up to four times longer than traditional sealed lead-acid batteries.
Installation is a breeze—simply connect the trolling motor’s main positive cable to the battery’s positive terminal and the main negative cable to the negative terminal. It’s truly a plug-and-play setup! Need more power? Up to four batteries can be wired in series to support 24V, 36V, or even 48V systems.
