Our Brand, Our Story
At K2 Battery, our mission is to revolutionize the way the world harnesses energy. With over 16 years of expertise in pioneering LFP battery innovation, we are committed to driving a sustainable future for businesses and individuals alike. Our journey began with a vision to create cutting-edge lithium iron phosphate batteries that deliver unmatched performance and reliability.
Cutting edge technology and impeccable customer service. Highly recommended!
These K2 batteries are perfect. They work exactly as advertised and the run time is a little longer than I had expected.
A lightweight and long-lasting battery
Over three weeks of -35C to -55C temperatures, so cold that any exposed skin freezes in seconds, combined with heavy cloud and snow for days on end. K2 Energy cells continued to operate our solar run lights for over 18 hours of run time with limited sunlight, snow cover and -35C temperatures for over a month.
I use one of these to run the fishfinder and other electronics on my fishing kayak. The battery has worked flawlessly for 2 years and counting.
Love this battery. Maintenance free and SAFE! I use mine for storing solar energy for DC powered projects and applications.
Unbelievably light weight. Will be perfect for running my QRP rig from the field. Amazing technology. Would recommend to anyone.
