Why Would You Choose Lithium As a Deep Cycle Marine Battery?

For the boat or angler, it is important to keep equipment such as depth sounders, live wells, bilge pumps, GPS, and fish locators working consistently, which is why lithium deep cycle marine batteries are becoming increasingly popular.

Unlike starter batteries, deep cycle batteries are ideal for renewable energy, electric forklifts and golf carts, as well as marine applications, as they require a constant supply of energy to electrical equipment. In the past, we have often chosen lead-acid batteries for powering equipment as they are the most affordable option, but for longer voyages lithium deep cycle batteries have become the star of the show for marine enthusiasts as they last longer, recharge faster, are lighter in weight, deliver consistently high power and have a longer cycle life. Lithium-ion deep cycle batteries are ideal for cruising sailboats, motorboats, fishing boats and campervans.

Lithium batteries have been around for a while, so there are a very large number of lithium-ion marine batteries on the market. If you are looking for a reliable power source for your marine equipment, what brands of lithium deep cycle marine batteries are worth looking at?

Is It Worth Choosing Lithium As Your Deep Cycle Marine Battery?

Although lithium batteries are more expensive than lead-acid and other types of batteries, they can achieve a cycle life of 4,000-6,000 cycles at 80% DOD compared to 500-1,000 cycles for lead-acid batteries, so they are cheaper to use in the long run.

Most importantly, Li-ion batteries can be charged quickly for more efficient use. You shouldn’t want to miss the best time at sea because you have to charge the batteries, and Li-ion batteries require no maintenance during use, whereas lead-acid batteries require regular acid top-ups, which can also be harmful to the environment and humans if the acid leaks.
