Features

Lightweight

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

More Usable Capacity:

Lead-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 Life

RELiON 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 Charging

RELiON 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 Tolerant

Partial 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 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).

Eco-Friendly & Safe

RELiON 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.

So far they are great, the weight and life of these batteries have made a world of difference in my bass boat. I have confidence that I fish all day without any worries. I can also fish swift water on high with no degradation of the amount of thrust I maintain to fish the fast-moving currents.

Frequently Asked Questions

Can I use my existing lead-acid battery charger (Wet, AGM or Gel) to charge RELiON lithium iron phosphate batteries?
Most likely, yes. Our lithium batteries are very charger-friendly. Most chargers today have a lithium charge profile, which is what we recommend using. AGM or gel charge profile chargers will work with our batteries. We do not recommend the use of a flooded charge profile with our batteries. These chargers may reach the overvoltage protection limit and disconnect. It won’t damage the battery but will likely result in charger faults. for more
How long will it take to charge a LiFePO4 battery?
Lithium iron phosphate batteries can be charged in as fast as 1 hour. We recommend using a rate that charges our batteries in 2-5 hours. Please refer to the data sheet for your particular model, to find the recommended charge rates. All of our data sheets are available on our website within the product section.
