Finding the Right Battery for You

As an angler, your time on the water is valuable. A bass boat needs reliable marine batteries as they are necessary for both starting and running your machine. Shorter charge times and more usable capacity without any late-day voltage sag means you can spend more time doing what you love most: fishing!

Lithium Benefits for Your Bass Boat

Lithium batteries have many advantages, making them the perfect choice for every angler

Lithium Advantages

Lighter Weight

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. 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

You no longer 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 a Battery for Your Boat?

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.
