Relion Low-Temperature Lithium Iron Phosphate Battery (RB100-LT)
This low-temperature version of the Relion RB100 LFP battery charges at temperatures as low as -4°F (-20°C), making it great for cold-weather off-grid solar (and other) applications. It features proprietary technology that draws power from your battery charger, requiring no additional components.
Lasting 10 times longer than a lead acid battery and weighing significantly less, Relion's lithium-ion batteries offer a cleaner, safer, and more reliable off-grid renewable energy storage solution. But that's just the beginning of lithium batteries' advantage over the tradition lead acid chemistry.
This 100 amp-hour battery delivers 3000-5000 cycles at a 100% depth of discharge. Most lead acid batteries offer cycle totals in the hundreds, and degrade substantially at discharge depths of more than 50% - meaning you don't get to use their full rated capacity. But the RB100-LT is tolerant of both completely discharging and operating at a partial state of charge without taking damage, which is a huge benefit when used in a solar PV system where extended periods without sunshine (and battery charging) are inevitable.
While ideal for off-grid solar applications, this lithium iron phosphate battery also works great in electric vehicles, RVs, and countless other applications.
