Solid State Marine Information

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.
