Inside Solid State Marine | The Future of Batteries for Boats

Join us for an exclusive factory tour with Tom Calef, Founder & CEO of Solid State Marine, as he shows us how solid-state batteries are being designed and built for the marine environment. From the cleanroom to laser welding, quality control, and safety testing, this tour reveals why solid-state technology could revolutionize boating and renewable energy.

Along the way, Tom explains the differences between lead-acid, lithium iron phosphate (LFP / LiFePO₄), and solid-state batteries, and we dive into topics like dendrites, graphene, delta-V, and integration with systems like Victron and NMEA2000.

If you’re curious about the future of marine batteries, sailing technology, and off-grid power, this is a must-watch.
