Why Choose Lithium for Your Sailboat?
Long days of adventuring call for long hours of power. Sailboats have numerous components that require serious energy. Having reliable deep-cycle power that can meet these extensive demands is crucial. Lithium sailboat batteries offer a solution to this need as they provide tremendous capabilities out on the water.
Lithium Sailboat BatteriesRELiON lithium batteries provide more power than lead-acid batteries and are typically half the weight. Boosting both performance and agility on the water.
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.
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.
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.
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).
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.
