    i attended the motorcycle show in san mateo ca. last weekend and one of the more interesting things i cam across was a lightweight Li iron battery for motorcycles. it seems unbelieveable when you hold one of these things......

    anyway i had just bought a new battery for my husaberg so i was SOL

    fast forward to today when my benelli TNT battery gave up. its cold here in n cal and it wouldn't cold start so....it turns out shorai is right here in sunnyvale so i went over there and picked up their most powerful model that has similiar dimensions to my old battery but is 3/4 inch less thick and get this......6.3 lbs lighter. 8.5 lbs lead acid to 2.15 lbs Li iron.

    anyway this thing is amazing so far. it has 270 CCA and turns over the big benelli like a 125. and they're priced the same as a facy gel/lead acid

    i guar-on-tee you these are the shit

    I will be curious to see how this holds up for you. Looks like a pretty sweet battery.

    Please keep us posted.

    I would really like to know how long your battery will last.

    When I first decided to get a Lithium battery for my 2007 525 EXC, it was purely because of the weight difference.
    I went to Baja Designs first because I have their DC conversion kit installed on my bike. They told me to stay away from Lithium because these batteries like a constant charge. They were not trying to sell me anything, just looking out for me.:norton

    $153.95+shipping for a DL1000. Pretty expensive battery

    They claim a 2 year warranty, which I believe is better than the warranty for the Uasa sealed battery I just bought 2 weeks ago. Also paid 150 and change for the Uasa. Damn if that thing only lasted another month I could of shaved 7 pounds off my bike.

    I'm waiting a couple years to get a handle on how that's working out.

    How will these handle extreme cold?
    Should be better, right?

    Then I bet they have no problems offering a 4 year warranty?

    If dropping weight is a priority then I would try this battery, otherwise not because you can get three batteries on that price. Of course my view according to my bike, which is about 200kg so a kilo there another here doesn't really tip the boat one way or another.

    Remember, that lithium ion is a common battery type in cell phones and other consumables and doesn't really hold charge that well in extreme cold temps. This should not be a problem for you Cali riders though. Also I'm on the presumption that li-ion batteries won't give much juice during starting which is the most important thing to most operating their vehicles in varying temps.

    The batteries for my cordless tools (Milwaukee V28) need a little bit of a "wake up" period before they come alive in really cold weather, otherwise they work really well.

    I think lithium-ion sounds like a pretty good idea for motorcycle use-- the temps at which they're affected are way too cold to ride.

    I haven't used the Shorai or TurnTech but am compelled to point out that they are NOT Li batteries like the ones in cell phones.

    They are LiFePo batteries which are quite different.

    There are a few members who have used the TT battery and reported good experience. There's already another battery thread that addresses a wide range of options. If you are concerned about your LC8 battery, it is a must read.

    They are affected by cold more than a conventional battery.

    How will they hold up after a 50 mile, extreme washboard dirt road knocks the hell out of it.

    The cells in Shorai LFX are not only quite vibration resistant natively, they are vibration damped inside the hard-shell carbon-plastic case. In most cases the LFX battery is also slightly shorter and narrower than the original lead-acid as well, so the supplied high-density foam shims are used to make up the difference, and this supplies further vibration and heat protection.

    LFX have been laboratory and field tested at extreme vibration levels, with 100% pass.

    As for cold weather performance, it is true that Li-Ion and LiFe batteries which are LOW RATE types (like cell/laptop, etc) are very affected. Even those, however, do "wake up" once they are slightly warmed. Shorai LFX are extremely low-resistance (high rate type), so cold temps affect them less than other lithium lower-rate cells to start with.

    A lead-acid battery under extreme cold will give its very best crank on the first shot. Then plate coating will increase resistance, and every crank after will be worse. LFX do the opposite. They may start slighly below the lead acid in voltage under cranking, but with one crank (or any other load, like a headlight on or heated jacket for a few minutes) they will decrease in resistance as they warm, and improve with each crank attempt.

    All the Best,

    12-13-2010: here is a report from a dealer who was tring to break an LFX much smaller than recommended, including freezing the battery, in order to "stress test" before making a volume order, ShoraiNews > Customer Reviews

    I'm sold on these batteries if they do what is claimed.

    And what I like is that they seem to have a fitment for most any bike unlike the Odyssey company.
    I don't want ordinary batteries----I'm always out in the middle of nowhere--none of my bikes have a
    kickstarter--so I want something that is the best money can buy.

    They have a fitment for my Yamaha WR250R which I was planning on getting a new battery for this winter.

    I'm all over it. I'll be getting 2 of these--one for my 950 and one for my WR250R.

    I'm going to be reviewing at least one of these batteries soon... for the LC4 and LC8. I will submit info to the other thread on battery alternatives.
