Legacy Series
Deep Cycle Lithium Batteries
RELiON's Legacy Series Batteries
Our deep cycle lithium batteries are the perfect drop-in replacements for Group 24, 27, 31, and 8D AGM, GEL, or lead-acid batteries. They are the perfect combination of size and capacity to fit many applications including, RV, marine, solar energy systems, and more. RELiON lithium batteries provide more energy for high consumption than traditional lead-acid batteries. They also offer ultra-fast charging and discharging, high efficiency, and longer cycle life – plus no maintenance!
Find Out MoreFull power is available throughout discharge. Voltage does not drop like lead-acid.
RELiON Legacy Series batteries provide more power than lead-acid batteries and are typically half the weight. Boosting both performance and agility on the water.
Legacy Series 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).
Plug, play, and charge. No watering, no corrosion.
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.
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.
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 a substantially longer cycle life.
LiFePO4 batteries last up to 10x longer than lead-acid.

RV Owner
Fantastic battery and peace of mind. I just finished a 3-week trip and never worried about the batteries once. Super fast recharge while driving my RV & my solar setup. Minimal drain during day use. I Should have switched to Relion years ago. Thank you!
