Our battery can withstand 4000 cycles of perfect charge and discharge before losing 80% of its factory performance, but it is still adequate for your needs. If you live completely off-grid, you will be able to use it for more than ten years at the rate of a full charge and discharge per day.

We use the most recent pouch cell technology in our batteries with patented BMS. We offer ten year warranty and local technical support in Canada.

These enclosed lithium-iron phosphate batteries are perfect for marine applications. They are suitable for use on your boat or pontoon. They can also be powered by a wide range of off-grid, emergency, and energy storage systems, including RVs, vans, cabins, solar/wind energy systems, UPS battery backups, telecommunication systems, medical equipment, and others.
