Lithium Batteries for Bass Boats

Power Your Passion

As an angler, your time on the water is your most valued asset. A bass boat needs reliable marine batteries as they are necessary for both starting and running your fishing machine. Shorter charge times and more useable capacity without any late-day voltage sag means you can spend more time chasing that fish of a lifetime.

Lithium Benefits for Your Bass Boat

Lithium batteries have a number of advantages making them the perfect choice for the avid angler


RELiON lithium batteries provide more power than lead-acid batteries and are typically half the weight. Boosting both performance and agility on the water.

Fast Charge Time

Time to charge is a major factor of each and every battery. Lithium batteries charge significantly faster than lead acid. Plain and simple. Our lithium batteries can be charged in as fast as an hour, but we recommend using a charge rate that charges them in 2-5 hours.

Partial State of Charge Tolerant

No longer do you have to worry about fully charging your batteries before use. With lithium power a partial state of charge will not damage the health of your battery or its long-term performance.

Increased Usable Capacity

Lithium batteries have more hours of power. With 25-50% higher capacity than lead acid batteries with full power throughout discharge lithium batteries eliminate the voltage sag that is all too common with lead acid and will keep you on the water.

Temperature Tolerant

Lithium batteries can handle a wide variety of conditions and are even 2.5x more efficient at low temperatures than lead-acid while being able to safely operate up to 149°F (65°C).

Maintenance Free

Lithium batteries are maintenance free. Lithium batteries last up to 10 times longer than their lead acid counterparts while still providing 80% capacity after 2000 cycles.

Need Help Selecting the Right Battery for Your Boat?

When selecting new batteries, the first step is to size your battery bank according to your needs. Generally, to get the same runtime as a wet or AGM lead-acid battery, use a lithium battery that is 60% of the capacity of the lead-acid battery you are replacing.
