The RELiON RB60 Lithium Iron Phosphate Battery is a safer, lightweight alternative to lead-acid in your marine, solar, RV, or other deep cycle applications. Weighing under 20 lbs. with 60 amp-hours means a full day of power for small trolling motors or for a long day on the road in your RV. More Usable CapacityLead-acid batteries are typically sized up to two times your energy needs to account for extended periods without sun and less usable energy with higher rates of discharge. Plus, you are typically cautioned to limit your use to 50% of the rated capacity, as using more can significantly reduce performance. Lithium batteries provide 100% of their rated capacity, regardless of the rate of discharge. And, you can use it all and still get substantially longer cycle life. Long LifeRELiON lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of the rated capacity after 3, 500 cycles. Fast ChargingRELiON lithium batteries charge much faster than traditional lead-acid batteries, and they're packed with more usable energy and up to 10 times longer life so you're always ready to go. Partial State of Charge TolerantPartial state of charge, known as PSOC, which is a killer of lead-acid batteries, does not affect performance or battery life of a lithium battery. Sometimes batteries don't get fully charged, or they regularly operate in a partial state of charge. Either way, you can count on RELiON lithium batteries living a long and productive life. Temperature TolerantLithium 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. Eco-Friendly and SafeRELiON lithium batteries are the ultimate clean energy. No gassing, no fumes, and no pollution. Enjoy reliable power, while protecting the environment, using these non-hazardous batteries.
