I don't know if they have this battery technology in large scale commercial production yet, especially in the larger sizes that marine use would require. Even if they did, it probably wouldn't be used in a marine environment initially, primarily due to costs.

 

costs are not a factor in using LiFePO4 packs.
1/2 the weight, 5+ X's the life cycles, higher output per smaller volume, flatter discharge curve, no negative impact on environment like lead, any voltage, Ah, ....what else you need to know ?

...

Can you explain how costs are not a factor in the boating market, where every penny is turned over twice (there are threads here about using an inkjet and other homegrown methods to print courtesy flags instead of buying them for $10 apiece!)?

Does that mean that the cost for a nominal 300Ah capacity with this new technology will be the same as or lower than Lead-Acid?

 

Yes, but what are the initial costs of the batteries. Many people aren't willing to shell out the bucks, especially on an unproven, in the marine environment, technology. Also, is the infrastructure to support the batteries available. Can you get chargers and inverters that will work with them. I don't think so.

 

yes, and yes.
but you can't afford them anyway, so why piss on them.

 

Just curious, who said I was pissing on them.. Can you point to the chargers and inverters that are marine grade and made or support the LiFePO4 battery technology. If not, STFU. I'm stating the facts , and you don't seem to like it... what is your relationship to LiFePO4 batteries anyways... and why do you need to go through an e-mail anonymizer??? That's what NYMS.NET is.

 

falconev...please point me to someplace I can buy one of these batteries in a 12V size with enough amp hours to be used on a boat (20 hour rate/100+a/h's).

 

All I can find on this technology is a 12V pack which supplies 10ah's for around $400!!! That would make the price of a group31 battery around $4000 bucks.

The Odyssey batteries seem like the best bang for the buck currently in available technology for full time cruisers looking for quick charging and high cycle life.

LiMn torqeedo

Hi

Torqeedo makes a 77 Ah (at 24 V!) marine LiMn battery that weighs only 18 kg and can be essentially fully discharged without loss of life-cycles. It is intended for their "power" 6 hp electric outboard.

see, e.g.:

torqeedo: Produktbeschreibung

and click on technical data

is their nothing those crazy germans can't do?

cheers

Torqeedo makes a 77 Ah (at 24 V!) marine LiMn battery that weighs only 18 kg and can be essentially fully discharged without loss of life-cycles.

And at only 3299 euros (about US$5,000) for just the battery! Plus $1000-1500 for a charger.
