The Best 36 Volt Lithium Marine Battery

ByJeff Godin

Introduction to 36 Volt Lithium Marine Batteries

The journey of lithium-ion batteries, from a mere concept in the 1950s to an integral part of modern marine applications, is nothing short of revolutionary. The evolution of these batteries, awarded the Nobel Prize in Chemistry in 2019, paved the way for their use in marine environments.

Lithium marine batteries, especially the 36-volt variants, have revolutionized boating. From the first BASS Federation tournament in 1967 to modern bass boats, the need for reliable, efficient batteries has been paramount.

Choosing the Right 36 Volt Lithium Marine Battery

When selecting a 36-volt lithium marine battery, size and weight are crucial considerations. Lithium batteries are significantly lighter, enhancing fuel efficiency and maneuverability. Additionally, power output and performance must be evaluated, particularly in cold weather. Many modern lithium batteries include built-in heating systems to facilitate charging in low temperatures.

Proper installation is also key. Most lithium marine batteries are designed to seamlessly replace older battery types without extensive modifications.
