Saltwater fishing is all about durability, reliability, and having the right gear to power through long, salty days on the water. The choice of battery can make a world of difference, and lithium batteries are emerging as a top pick for saltwater anglers everywhere. Here are the top reasons why lithium batteries are making waves in the fishing community and are better for your fishing boat:
- Lithium batteries lighten the load of your boat
- Lithium batteries last longer for powering fishing electronics
- Lithium batteries have rapid recharge times
- Lithium batteries are built for tough conditions
1. Lighten the Load
One of the biggest perks of lithium batteries is their weight—or rather, lack of it! Lithium batteries are nearly half the weight of traditional lead-acid batteries. In a saltwater fishing boat, less weight means better handling, faster speeds, and improved fuel efficiency. Whether you’re moving from spot to spot or navigating through choppy waters, the lighter load helps your boat ride smoother and makes it easier to stow other equipment.
2. Longer Lasting Power
Imagine not having to worry about power fading just when the fish start biting. Lithium batteries deliver consistent power, holding voltage all day long. That means your trolling motor, fish finder, and electronics run at full strength, keeping your boat ready to roll until the last cast.
Not only do lithium batteries last longer per charge, but their lifespan outlasts lead-acid batteries by a long shot. Some lithium options handle up to 5,000 charging cycles, while lead-acid batteries max out around 1,000. In other words, one good lithium battery can outlast several lead-acid batteries, saving you replacement costs in the long run.
3. Rapid Recharge Times
If you’re back-to-back fishing or need a quick turnaround, lithium batteries are your best friend. Lead-acid batteries can take up to 8 hours to recharge fully, but lithium can be ready to go in as little as 2–4 hours, depending on your charger. That’s a big deal when you’re out for a full weekend or need a quick top-off before heading back out.
4. Built for Tough Conditions
Saltwater environments are no joke, and they can be rough on your gear. Lithium batteries are up to the task, with tough casings that resist moisture and corrosion. High-quality lithium options are built with sealed designs and rugged exteriors that stand up to the salt spray and vibrations common on a fishing boat. For example, RELiON’s RB100-HP 12V 100Ah lithium iron phosphate battery offers an IP rating of IP67, which helps to completely repel both dust and water ingress. The IP rating of “IP67” offers one of the highest levels of protection that an IP rating can be for both solids and liquids.
Additionally, lithium batteries tolerate deeper discharges - up to 100 percent - compared to lead-acid batteries, so you don’t have to worry about draining them fully. They can take the stress of heavy use without breaking down as quickly, making them ideal for serious anglers who are on the water regularly.
5. Eco-Friendly Performance
For those who love the ocean and want to keep it thriving, lithium is a greener choice. Lead-acid batteries contain hazardous materials like sulfuric acid and lead, which can leak and harm the environment if not disposed of properly. Lithium batteries have a longer lifespan, which means fewer batteries need to be replaced and disposed of, leading to less environmental impact. Many lithium batteries are also recyclable, so it’s a win for both performance and sustainability.
Real-World Benefits: Anglers Share Their Lithium Battery Experience
Many saltwater anglers who’ve switched to lithium batteries notice an immediate improvement in their experience on the water. Reports of “endless power” on trolling motors, faster recharges, and zero drop-off in performance are common. Plus, the light weight makes it easier to install, and the consistent power keeps critical equipment running without interruption.
In the words of one angler, Captain Leon Dana, “From weight savings to battery life to power output, there is no comparison to lead-acid batteries.” Professional fisherman, Chris Cenci, also expressed: “These batteries are the most powerful, reliable, and true to voltage. I only use the best, and I recommend RELiON batteries to everybody. Make the switch and your system will be lighter, go faster, and last longer on the water.”
If you’re looking to make a solid upgrade to your fishing setup, a lithium battery could be the perfect addition. With lighter weight, faster recharges, longer life, and rugged construction, they’re engineered for saltwater fishing.
