Solid State Marine is revolutionizing the maritime industry by introducing the next generation of energy storage. Headquartered and proudly assembled in Pawtucket, Rhode Island, we are on a mission to deliver the most reliable and safest battery in the smallest form factor as possible.

Traditional lithium-ion (LFP) rely on liquid electrolytes, which limit performance and introduce safety risks. We have replaced that liquid with a revolutionary solid electrolyte, unlocking performance metrics previously thought impossible. Our batteries are half the weight of lithium and a quarter the weight of lead-acid, allowing for massive weight savings without sacrificing capacity.

Our technology thrives where others fail, offering 8x the lifespan of leading lead-acid batteries and maintaining full functionality in extreme conditions—including charging and operating at temperatures as low as -4°F. Designed and assembled in the USA to meet rigorous Military and ANSI standards, Solid State Marine provides the ultimate replacement for trolling motors, engine starting, and electric propulsion systems.
