vacendak,

There are several advantages. The big one is the microcell 3-D technology which is highly resistant to corrosion and to sulfation. These are the biggest killers of lead-acid batteries.

The Oasis has a much longer cycle life than does the Odyssey. The latter claims 400 cycles at a 80% depth of discharge (DOD), while the Oasis may be as much as ten times that number of cycles at the same level of discharge. See the chart on page 13 of the Firefly white paper.
http://www.fireflyenergy.com/index.p...=201&Itemid=96

Note that while Odyssey claims a typical 6-8 year lifespan, a cruising boat spending most of it's time away from shore-based charging facilities could easily rack up 400 cycles in less than two years.

It remains to be seen in actual practice if these differences are real. However, I'm impressed enough with what I read, and with the businesslike way Firefly is going about their research, manufacturing, and marketing to believe that the wait may indeed be worthwhile.

We'll see :-)

Bill

That's right, Bill

I missed the whitepaper

but we should see the price, too
Valence batteries have outstanding parameters, but I could buy
a slightly used MB for a value of their 600Ah / 24V battery pack

Absolutely right! I'm waiting for the price announcement, too. But, I'm hopeful, because they talk about the low cost of manufacture. We'll have to see how greedy they get :-)

Would really love to put one thru it's paces.
Ah, was that a "scantily clad beauty" you were referring to Bill? <gr>
