Lithium Solar Batteries

The Most Powerful & Efficient Batteries for Energy Storage

Why is LiFePO4 the ideal choice for all your energy storage needs?

Lithium deep cycle solar batteries are the ultimate clean energy, delivering highly-efficient, ultra-long life and constant power you can depend on from home energy storage to backup and emergency power. Lithium iron phosphate batteries, charge faster, keep their charge longer, offer more usable capacity, they have a much longer life and they’re completely maintenance free. Lithium solar batteries make it easier than ever for you to live off the grid.



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.


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.

PSOC 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.


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.


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.


Lithium batteries are designed to perform in harsh conditions–freezing cold, scorching heat or rough waters.


Unlike other lithium chemistries, RELiON LiFePO4 batteries are inherently safe due to their stable chemical composition.

What Our Customers Are Saying

Reliable Power Through the Storm

Reliable Power Through the Storm


“Just thought you'd like to know that with our grid down for one week after Hurricane Ian I was powering my entire house with solar and six of your RB48V300 batteries (A/C, washer, dryer, water heaters, oven, cooktop, others). The batteries never even broke a sweat! About 240 Ah used after dark and by 10 a.m. the next morning batteries were back at 100% charge. Thank you for this truly great product.” - David Adams
