Marine-Grade Lithium-Ion Batteries

BigBattery's lithium-ion solutions are revolutionizing marine power with their unmatched efficiency and reliability. Perfect for trolling motors, yachts, and boats of all sizes, our next-gen HUSKY 2 and EAGLE 2 marine batteries are equipped with advanced protections for any marine environment and are always quality installed with zero routine maintenance, so you can get up and running quickly and set out worry-free every time.

Why Lithium Marine Batteries?

Compared to traditional lead-acid options, a lithium marine battery will offer superior energy density, with charging up to 4 times faster, so you can stay out longer without issues, and our lithium kits include cutting-edge inverters, chargers, and components from household names such as EG4, Victron Energy and AIMS Power. BigBattery offers a range of kits and capacities so you can be confident there's a solution for your energy needs! Plus, lithium batteries are maintenance-free and deliver much longer lifespans than lead-acid alternatives.

While lithium marine batteries offer benefits to boaters of all sorts, for those who use their batteries to directly power trolling motors, they're even more valuable. Lithium deep-cycle marine batteries provide more power, and are more steady and reliable for longer durations of time, making them ideal for powering trolling motors, fish finders and other invaluable electronic equipment.
