What is the LT Series?

The LT Series lithium iron phosphate batteries are cold-weather performance batteries that can charge at temperatures down to -20°C (-4°F). How? The system features proprietary technology that draws power from the charger itself, requiring no additional components. The entire process of heating and charging is completely seamless. Simply plug the battery into the regular lithium charger and the internal heating and monitoring system takes care of the rest.

Same Battery, Enhanced Technology

Our Low Temperature Series batteries look and operate exactly like our other batteries, with the same power and performance. They have the same charge time at above-freezing temperatures. They also feature the same dimensions, configuration, and connectivity of its standard counterparts, making them drop-in replacements in applications that already use RELiON batteries. And they’re ideal upgrades for those who are still using lead-acid batteries in low-temperature environments.

Customer Testimonial

LT Batteries Perform Way Above Expectations

LT Batteries Perform Way Above Expectations

Off-Grid Adventurer

"As a full-time geek adventurer, my power system is critical. It has to function or I don't have a job. These batteries take a charge quickly and have an amazing amount of capacity as compared to my previous VLRA Gel Hybrids. The difference is stark. For instance, with my old setup I had problems keeping the 4x 100AH bank fully charged with 400 Watts of solar and an MPPT controller. Mostly because the bank would not take the charge current efficiently. My new RELiON setup is 200Ah and is charged by 200 Watts of solar. They're fully charged in no time. The ability to charge these "LT" batteries in cold temps was a huge selling point for me. They're just easy. No fuss, no worry, they just work great. I don't have to be constantly worrying about my usage or State of Charge."

"These are the only lithium batteries made for those of us who explore into truly wild areas that have unpredictable weather. All of you competition requires a significant amount work to insure the battery bank will stay warm."

Customer Success: RB100-LT Battery System Provides Reliable Power in Extreme Colorado Cold

Born and raised in Wisconsin, Jason Bucholtz was no stranger to the extreme cold temperatures he encountered in his new home in Colorado, but he had never before had to find a way to deliver reliable power in below freezing temperatures to a remote cabin miles from the nearest utility connection. Jason’s cabin is so remote that he relies on a snow vehicle just to reach his property, particularly as the nearby logging roads are not maintained.
