Relion Lithium Iron Phosphate Battery (RB48V300)

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 300 amp-hour battery delivers 3000-5000 cycles at 48 volts 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 RB48V300 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.
