About Us

Monster Marine Lithium is a battery company designed and built for anglers by anglers. We here at MML got tired of dragging around all the extra weight, not to mention the unexpected acid battery dying on us during a bass tournament, so we developed and designed a battery that would allow us to troll all day and run all the needed electronics, live wells, lights, and even video cameras in your boat without worries. We also have a built in display on the battery for the voltage and percent battery remaining. 

Fish More; Charge Less!
