New Lithium Ion battery for us?

I was in West Marine buying some 12 volt circuit breakers and came across some interesting info about a company named MasterVolt that supplies electrical components for yachts. They are selling a Lithium Ion battery that has 320 Ah at 12 volts. They say you can use the entire 320 amps with no damage and be totally discharged 2000 times. I have a lead acid 1150 AH battery pack that I really shouldn't go below 50% discharge. That would mean I only need 2 of them to equal what I have. Anybody seen these or have any more info? I don't know how much they are selling for yet.

    Like the guarantee - 2000 cycles or 2 years. In a RE application I wonder which will happen first.

    Lithium ion batteries - from what I know you do not want to leave them fully charged nor fully discharge them - they need to float in between.

    They don't mention cost.

    Not to mention the 24 hour watchman to guard Fort Knox or would that be Fort Mike?

    This is a prime example of one of the biggest stumbling blocks to advancing RE systems: people unwilling to pay a little extra money to further the cause! :p

    I'd need two of those batteries Mike quoted for my system. Let's see, how man L16RE-A's can I buy for $12,000? About 40. Or ten total battery changes. Enough to last 100 years, which I certainly won't.

    Can someone explain why they have the same discharge at C1 all the way to C20?

    thanks

    LI batteries have very low internal resistance and very "fast" chemical reaction times... The battery outputs the same AH at C/20 to C/1 test currents.

    From the rating sheet, they support:
    Pulse current (10 sec) <3200 A

    Or C*10 surge current vs C/2.5 as the typical surge current for a flooded cell lead acid battery. Or ~25 more current for a similar AH rating.

    Okay, loan me $12,000. Real CDN$, please; not that Australian Kangaroo money. :p
    I'll pay you back - in 100 years.

    Maybe someday these will be common enough to bring the price down to reasonable. Then all we'd have to do is solve the 18% efficiency panels problem. That will probably take some time and technology like the x-ray etching of microcrystals or something.

    One of the scary things with new tech batteries, I was introduced to the ability of NiMH batteries quick discharge, when I put a pack of 4 in my pocket while photographing a wedding, shorted out against some change, smokin', and a melted plastic carrier, and blistered thigh, these were 16 or 1800 mA.

    I have done the same with alkaline - but it only gets a bit warm to tell you the batteries are probably now useless.

    It's easy to make mistakes with any battery technology. I used to SCUBA dive using rechargable batteries in my backup light. One night I decided to discharge the NiMH batteries in the light, so I turned it on. The next morning when I them out to put them in the recharger, I found out I'd put Duracell's in instead of the rechargables.

    Oops! One dead set of batteries!

    Me too. Even though CDN$ is higher than the US right now it doesn't seem to have improved purchasing power one little bit! :grr

    Hope I'm not out of place on this - still pretty new. These are the newer tech Lithium Iron Phosphate batteries. They are also half the weight of normal batteries.
    The military has been using them and now some private companies are. Powerenz uses them in their high end portable systems. If you google them a company comes up that assembles them. You can still buy a 55 Ahr with charger for 1,300.00 if your quick!
    Hopefully the price will come down quickly.

    Fish,

    You are fine--We always appreciate information about exiting and new technologies.

    I believe this is the site you are referring to:

    Yes, that's it. Thanks for the link - I think lots of folks here might like to browse through it. Great videos of the products.
