Monster Marine Lithium | 1500 CCA 300AH Dual Purpose Cranking Lithium Bluetooth "Sea Lion"
Overview
This high-performance cranking lithium battery not only meets but exceeds Mercury Engines' latest spec bulletin in every category!
A common question we hear is, "Will it work with my engine?" The answer—absolutely! We've personally tested it on family and friends' boats for years, as well as with top professional anglers running full tournament seasons. It has been proven reliable across a wide range of engines, including Mercury Pro XS 4-stroke, Yamaha 4-stroke & SHO (both older and newer models), Yamaha HPDI, Mercury Verado 4-stroke, Suzuki 4-stroke, Evinrude 2-stroke, Mercury Pro XS 2-stroke, and Mercruiser 4-stroke. These tests have spanned over a year, ensuring unmatched performance and dependability.
The Sea Lion is our most compact yet energy-dense dual-purpose lithium cranking battery, packing an impressive 1500CCA and a massive 300Ah capacity. Engineered with an advanced BMS system, Bluetooth monitoring via our app, and Grade A cells, it’s built for serious power demands. Whether you need multiple days of runtime without charging or a battery capable of supporting offshore boats loaded with bait tanks and electronics—this one does it all.
Running 6-10 graphs, Mega 360, multiple Livescopes, shallow water anchors, bait tanks, lights, and pumps? No problem. The Sea Lion is built to handle everything you throw at it!
