Talked to the rep at the show and it will be my next battery. Very nice and light, when i picked it up thought it was just a demo with no guts.

LiFePO4

Very exciting technology, still in it's infancy resulting in high cost. One nice feature is it does not need to be kept fully charged while in storage as a lead acid battery does, extremely light by comparison and apparently not as toxic or hazardous. Sounds like a win, win situation to me! Just as with everything else, early adopters will pay the premium price, but at 1/5 the weight, I want one :D
...thanks for the tip

I found this on another site as well - some additional info about lithium batteries and Shorai...

I can answer some of your questions and you can visit the site...http://www.antigravitybatteries.com/ for more in depth info.

The lithium battery won't really help a lot if your bike doesn't start well in the first place.. but what it does offer if a little bit quicker turn over rate because of higher Cold Cranking Amps, but there are differences in the lithium Lifepo4 batteries like the Shorai Company in your post....

There are two different types of Lithium Lifepo4 Cells... Prismatic and Cylindric... being blunt the A123 Cylindric cell is the only tried and trusted unit that has major cranking amps. A123 systems is the real originator of the lifepo4 chemical makeup that is the industry standard. There are many Chinese knock offs in the Cylindric style, but nothing comes close to the peak amp output or constant amp rate, so no one uses them. The Shorai in your picture is made of Prismatic Cells... Prismatic cells do offer higher Amp Hours, but much lower cranking amps than Cylinderic. They do offer the weight saving though. I like their case alot and the price is very good. But they are not close in power relatively speaking to a battery made of A123 cells....But then again if they used premium cells the batteries would be more expensive. For example their 7 amp hour battery puts out 107 CCA... a comprable 7 amp hour battery using A123 cells (like our Antigravity 4600) puts out 240 Cold cranking amps twice as much... and that will actually spin your motor faster. I actually use the 4-cell in my SXV 550 which is 2.3 amp hours and puts out 120 CCA... So there are trade offs in price performance and looks... just do some research first.

I just got an email from a local place that is going to sell the "Antigravity" batteries. The last start I made with my GT was a little ponderous, not sure if it was going to start or not. Although due to several factors (MOSTLY me being a wimp) the bike had not been ridden much up until the point I put it away. (If this keeps up I might have to get a cruiser or something stupid like that). Anyways, the bike is an 07, bought in Aug 08 new (leftover 07), and has the original battery, which from the sounds of it might be some sort or record. With the battery mounted so high in the bike I would imagine a superlight battery would be big check in the "plus" column. Any comments? No, not about me being a wimp.

Gentlemen.

While the prospect of spending lots of $ to save a pound, the weightconsious among us will find the largest potential of weight saving by consulting the bathroom scale.

New technology is always fascinating. And if you want it, buy it.
But the weight saving is neglibel. Why spend extra money on a "super" battery as long as the regular one does the same job for less money?

I know the answer to this :D ...you are saving the planet
, you are saving way over one pound.
and they report that LiFEPO4 is better suited to non continuous use with extended periods of storage at 30~40 percent charge. :alien: technology
...add, I weigh 145 lbs. and it's all sprung weight :borg

I use lithium batteries in all my electronic laptops (I got 6 notebooks to chase around.). The things only last about 18 months and then they die very fast. I've wondered if they don't have some sort of coffin-nail chip in them to kill them off just outside the 12 month warranty.
Same goes for the metal Ni-Mi or whatever they call them small AA sized things. I had two die one me last week that I threw out. Absolutely no volts at all out of either one nor would the charger even wiggle them back to life.

The new die pretty fast and hard, imo. Lots of amps, but not lots of life.

..Just run with 1 gal less fuel in your tank...not only do you lose weight you save 3 bucks...And every fuel stop in the next 3 months the savings go up..buy the end of March you should be saving around $4.50 per stop...its a win win :D

3 bucks a gallon, I wish! Try $4.28 per US gal. ...if I switch to Hydrogen fuel and run Nitrogen in my tires, will that put me on the minus side of dry weight? :crazy:

I'm with you on this one. They just miss the point don't they... :D

Everything works better when lighter. And all those other things aren't mutually exclusive of each other. Lose fat, half fill the gas tank, lose pounds on the motorcycle. They all add up. 1-2 pounds in 10 different places means a SIGNIFICANT weight reduction.

I understand the "lose weight" comment. Does my computer have a camera on it someplace, can you guys see me? heh heh :confused:

The thought was that since this battery is "so much" less weight than a lead/acid or AGM battery that it really would help, since the battery is so high on the bike. The fuel tank of course starts at about the same height but does go quite low in the frame, compared to the battery anyways.
Oh well, just wondering about it.
The thing that also makes me wonder is that the BMW spec for the battery is something around 19 ah (amp hours), and the specs on these lighhtweight batteries are under 5 ah???

You're absolutely right. I'm running a completely stripped K12R and have been running fine. But I don't have esa, servo brakes, abs, headlights, turn signals, or even a dash. I'd imagine some would run into problems sitting in traffic, servos going on/off, highbeams on with the gps, radar detector and palm pilot on. :)

Some motorcycle pilots need to lose weight. That would be more significant than a battery

Like I said above, it's additive not mutually exclusive...

I dunno, I'm sold on these glasspacks.

these things don't seem to die but they sure are expensive, about 2 bills if i recall.

soon as I hear any strain on starting I replace the batt, can't afford to get stranded...usually every 3 years or less, never more.

I use my bike for everything, since I don't own a cage.

Meaning when I go to work 400-3000 miles away at times, maybe in cold weather et el, I don't want any breakdowns. Not to mention towing, etc.

Tires, batteries, oil...I don't worry about losing 50 bucks on an item if it is not going the next distance I need it to, it is more important that I get there on time if I plan on continuing biz trips on the bike, from my employer's perspective.

Obviously I don't experiment much with components, if its near time to go and it is mission-critical, it goes! :)

If it was just a hobby, sure I'd run parts until they failed. :dunno:

so take my comments with a grain of gunpowder :boom: they are skewed a bit. But still, I'm real happy with the glasspak, amazed actually after a 4 month sit, quick charge and it works like new.

It has come to my attention that these batteries are not the same as the lithium ion A123 battery cells that I am using.
