At IBEX 2024 in Tampa, Solid State Marine showed off their new solid-state batteries for boats. These batteries are IP67 rated, meaning they are waterproof and dustproof. They are also about 50% lighter than traditional Lithium Iron Phosphate batteries. What's really interesting is that these batteries have apparently been shipping since April of this year, making them available for boating applications now.
The Future of Marine Batteries
Solid State Marine is making waves with their new solid-state batteries. This is a big deal because people have been talking about solid-state batteries for a long time, wondering when they would actually be available. Well, it looks like they are here.
One of the most noticeable things about these new batteries is their size and weight. A solid-state cell is much smaller and lighter than a comparable lithium iron phosphate cell. For example, a 100 Ah, 48V lithium iron phosphate battery might weigh around 100 pounds. A solid-state battery with similar power, like 120 Ah, could weigh only 56 pounds. That's a huge difference, especially for boats where weight can impact performance and fuel efficiency.
Key Takeaways
What Makes Them Special?
- Lighter Weight: Solid-state batteries are significantly lighter than current lithium iron phosphate batteries, which is great for boats.
- More Compact: They take up less space, freeing up room on your boat.
- IP67 Rated: This means they are built to withstand marine environments, being waterproof and dustproof.
- New Technology: While new technology often comes with a higher price tag, the benefits might outweigh the cost for many boaters.
Cost and Availability
It's true that new technology often costs more, and these solid-state batteries are no exception. While a 100 Ah, 48V lithium iron phosphate battery might cost around $1,700, a solid-state battery with 120 Ah will likely be more expensive. However, considering the advantages in weight and size, the extra cost might be worth it for those looking for the latest and greatest in marine battery technology.
Solid State Marine has been shipping these batteries since April, so they are not just a concept anymore. They are real, and they are available for purchase. This marks a significant step forward for electric boating and marine power systems.
Why This Matters for Boaters
For anyone interested in electric boating, this is exciting news. Lighter, more compact batteries mean more efficient boats, longer range, and potentially more space for other gear. The fact that they are already shipping means that this isn't just a promise for the future; it's a reality now. It will be interesting to see how these batteries perform in real-world conditions and how they change the landscape of marine power.
