I'm sorry, but.....a "solid state" marine battery? Throughout modern history, the term "solid state" meant a transistorized circuit, with no moving components. (i.e.; point-type transistors)
Now, I'll concede that a battery of any type has "no moving components", but there is a chemical reaction in order to generate both voltage and current. So, I can only presume that a "solid state" battery has NO chemical reaction going on to generate the power it's supposed to produce. That leaves only one alternative in my shoulder-mounted vacuum chamber. It must be a capacitor bank that stores a charge, and releases it on demand. With a calculated resistive circuit, one can slow the discharge rate, but once it's depleted, there isn't any more.....it MUST be charged again from an outside source. Usually, a capacitor is a one-shot deal. I suppose, with a carefully calculated resistive circuit, one might be able to stretch it tow 2, or even 3 attempts at starting, but I think that would be the maximum limit.
In that, it is similar to a lead-acid battery, but that's where the similarities end.

I can just imagine the issues one might have out on the water, say with water-contaminated gas. It wouldn't be enough to get a fresh gas supply, but you'd also have to "charge" the cap bank in order to attempt another start cycle.

Personally, I smell a marketing scam.

Should have said...what is a solid state battery ?
A solid-state battery is an electrical battery that uses a solid electrolyte for ionic conductions between the electrodes, instead of the liquid or gel polymer electrolytes found in conventional batteries. Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium polymer batteries.
 
I checked out the website and they are a little short on details. Looks like a fly by night operation to me. In this case I’d take the term “solid state” as a marketing buzzword more than a battery technology.

Edit: Retracting the “fly by night” and “marketing buzzword” statements. I stand corrected.

I see they have only been in business since 2023. I would have to give them more time to get a foothold before I could trust them myself.
 
I'm not an "early adopter" on this kind of stuff. Like all other new technologies, I'll let the newness wear off, pros and cons become evident, and the price come down (way down) before I jump in. Besides, maybe my two year old LiFePO4 will need replacing by then.

The description on the batteries seems to indicate that these batteries can serve as both the trolling motor battery and as the cranking battery. I'd like that if it's true.
 
Solid state (solid electrolyte) batteries are a thing and being worked on aggressively by transport companies as they'll be a huge leap in range for cars, etc. But I'd be wary until you see them in common use in other commercial applications. As others have said, let somebody else work the bugs out. Once they show up in 100,000 cars or 100,000,000 smartphones--then I'd dive in.

Water has 3 states solid, liquid, and gas and it has nothing to do with transistors.

Water in a solid state is called ice or you could call it solid state water.

Solid state batteries are no scam, they have been in work for years.

There are car companies working on these types of batteries. All still in prototype phase. Nothing ready for production. I'd be surprised that a company would come out with it first, in a marine application.

The promise is longer range, more dense, and faster charging. I'm sure it has to go thru allot of safety tests, as well.

They claim to be ABYC certified and UL1642.

That's kinda what surprised me when reading about them.

A quick internet search showed several companies are claiming this technology. Not proprietary or patented?

Also, at least one had prices. I may be dust before they become affordable.

I just bought a LiFePO4 and thought that was cutting edge.

I think LiFePO4 is all anybody needs for current recreational fishing boat tech. The promise of sodium batteries or solid state is likely to be realized in effective electric outboards.
 
Hi Everyone,
I saw that there was a bit of traffic to our site from tinboats.net, so I thought it may be good to register and introduce ourselves.

I agree that our website is not the best and I promise, we're on it! We've been focusing on manufacturing and the product (here in W. Bridgewater, MA), and we probably haven't put the right amount of time into the site. We'll have more content and helpful data up there soon!

In the meantime, If you do a quick search on instagram or youtube, you'll see our batteries in use for starting/cranking, trolling motors/thrusters, and as main propulsion batteries for the electric outboards that are becoming very popular.

If there are any questions, please feel free to ask. I am very transparent on what our battery is, and what it is not.

thanks!
Tom
 
Hi Tom,
It’s really great that you reached to the forum to dispel a lot of speculation.

The solid state batteries are still quite expensive. I was an early adopter of LiFe PO batteries for marine applications some 15 years ago and the technology wasn’t cheap back then. I paid something like $650 for a 60A/hr battery plus $150 or more for a charger. However, it was a good investment.

So a big advantage of SS batteries compared to LiFePO is operation as a cranking AND deep cycle battery. This leads me to ask about charging since a cranking battery is connected to the engine’s alternator which may not provide optimal charge current and voltage.

So two questions:
1. Will the above application reduce battery life and capacity?
2. Can you alleviate this issue by topping of the battery after use with a recommended CC/CV charger?

Just thought of one additional question. The charging and operating temperatures are better than a non-heated LiFePO. What is the minimum storage temperature?

Thanks for your time.
