Lithium Batteries to Go Off Grid

The Ultimate In Clean and Reliable Energy

Power for a Sustainable Lifestyle

The idea of living off-grid is appealing to many—it means living every single day in the fresh air and a more sustainable way of life- putting less strain on the environment. When you're self-reliant, battery anxiety is the last thing you need to worry about. That's why many of those that seek an off-grid lifestyle choose reliable, long-lasting lithium batteries for a worry-free energy storage system.

Lithium Benefits for Renewable Energy

When you’re powering your home or business you need energy that you can depend on around-the-clock. When you use RELiON lithium batteries as part of your solar energy system, you know you’re making the absolute most of it. That’s because RELiON batteries are the ultimate clean energy, delivering highly-efficient, ultra-long life power you can depend on in even the most extreme environments.

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.

John M

"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)."

“The energy system is key. I did a ton of research and comparisons before deciding. In the end, you really get what you pay for. I know some people who initially thought about using lead acid batteries because they’re cheaper upfront, but do you really want to be sleeping next to that? It’s better to make an investment in a safe, reliable system if it’s going to be in your home, especially near your children. With RELiON batteries, you have no maintenance, no toxicity, and no noise like a generator.”

Lithium Powers Up Solar

Investing in solar is smart; pairing solar with a lithium battery storage unit is even smarter. While lithium batteries tend to be a higher initial investment than lead-acid batteries, their superior performance and longevity make them an ideal choice for off-grid and grid-tie applications.
