Lithium Benefits for Renewable Energy

When you’re powering your home or business, or mission-critical remote monitoring equipment, you need energy that you can depend on around-the-clock, no matter if you’re on or off the grid. RELiON Lithium Iron Phosphate (LiFePO4) batteries offer safe, clean and high power energy solutions for all types of renewable energy systems.

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.

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.

Highly Efficient

RELiON lithium batteries have super low resistance, allowing you to charge much faster. And lithium batteries are 99% efficient, minimizing the losses during charge. Compare that to traditional lead-acid batteries at 75-80% efficiency, which results in significant loss when recharging.

Long Life

RELiON lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of rated capacity after 2,000 cycles. Spend more time powering your applications and less time replacing your batteries.

Maintenance Free

RELiON lithium batteries are maintenance-free – no watering, no corrosion. Low self-discharge means the batteries don’t lose capacity when they’re idle, assuring that you have the energy you need, every time you need it.


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.


Making the Switch to RELiON Lithium

"I have a bank of 12 RB100s in a 4S3P configuration. The highly efficient charging of LiFePO4 batteries helps make solar energy affordable in northern Pennsylvania. RELiON has the widest selection of LiFePO4 batteries (12 to 48V, varied Ah capacity). The batteries are top-notch, online ordering is easy, sales and support staff are great (and located in the US)."
