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 our patented BMS. We are a brand that manufactures its own products to ensure our product quality at a competitive cost. 

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.

No Regrets for this battery

No problems at all with sealed battery.Using inside my Astro Van as my house battery. Use with electric fan in summer and diesel heater in winter.Also with inverter PS4 and 24" TV plus charges iPhone iPad and more. Bought a battery isolator so it recharges while driving. Plan to ad solar panel and electric cooler soon.

As advertised

Battery was as advertised. This is my 2nd ROCKSOLAR LiFeP04 Battery and have been happy with both.

This Battery was delivered as expected and in great condition

This Battery was delivered as expected and in great condition. It was fully charged and included the 1 inch 8 mm post bolts. I have not had a chance to install it at my cabin and connect it to our simple 20w solar panel setup, but I do not anticipate any problems down the road.

Great job

I hooked up two of these batteries in parallel. They did a wonderful job powering my camper during two weeks at Big Bend NP. I used 200 W of ROCKSOLAR solar panels to keep them charged. I am very pleased with the batteries.
