    that's good to know .. no parasitic drain. something simple as leaving your key on can drain your battery completely to dead. what kills LiFePO4 is leaving battery in total discharge state for extended periods.

    not saying you did this .. but accidentally leaving your key on for a few weeks .. will drain any battery completely dead.. killing it.

    Had an issue with my 18A1. Called them and was asked to fill out an RMA and bring it in ( they are four miles from my house) so I went by. They gave me a new battery and I bought one of their chargers. I have the same battery in my Busa as well. I'm very impressed by the customer service and I'm happy with the batteries.

    more information please ... what motorcycle did the Shorai LFX18A1 fail in how did it happen?

    we already know the folks at Shorai has excellent customer service and will replace batteries for reasons not their fault. consumers installing recommended LiFePO4 models, which are severely undersized leading to early failure is not the fault of customer.

    wouldn't it be good to figure out why your LFX18 A1 failed? otherwise it may fail again .. next time not under warranty.

    Im chasing an electrical gremlin on my 05.5 950ADV. The battery was pulled down to near flat and I believe that while trying to start the bike thinking the battery needed a heat cycle that I killed it completely. Seeing that they are very close I called Customer service and was told to bring it in. They handed me a fresh battery on the spot with no hesitation.

    Closing the loop on my 3 failed batteries - FedEx just brought 3 new batteries. So we will see how these perform. While I can't say I've had good luck with their products (yet), I can say that their customer service is excellent! Very impressed with how they handled my issues. Kudos to Shorai on their service!

    I ran a Shorai LFX 18 battery in my 990 SMT which worked fine until it would no longer turn the engine over. After discussing the problem with Shorai, they did replace the battery with a new unit under warranty. Note that the 18 Ah rating, as already mentioned, is greatly exaggerated.

    I have used the Shorai LFX 12 battery in my Beta dual sport bike and it was no longer functioning after about a year. I have had much better success with 5 Ah TurnTech batteries in my dirt bikes. Currently over six years in my '08 KTM HTR 350 XCF-W and still going strong; eight years in my '04 KTM 540 EXC and still going strong with the current owner of the bike.

    early Shorai LFX18 were 5AH actual .. some of the current LFX18 are about 7AH actual. both would be marginal for moderate temps. certainly not enough AH capacity for adventure duties far from support including cold temps.

    for adventure duties stuff the largest LiFePO4 that fits into 990 battery tray .. that would be EarthX ETX36 (14AH) .. folks that's gone this route has reported excellent results even with cold temp starts.

    it's a good idea to keep track of LiFePO4 voltage with putting bike away for the night. 13.3v (90%) is desired voltage and indicates everything is working well.

    a desirable upgrade for 950/990 is MOSFET R/R ...

    are you saying you've had a 5AH Turntech LiFePO4 installed in two of your bikes for 6 years and 8 years?

    Absolutely. 6+ years, 8,332 miles (411 hours) in my '08 350 and 8+ years, 14,000+ miles (640 hours) in my '04 540 EXC which I sold to a friend about 2 years ago. Note that the 540 had one of the older shrink wrap versions of the TurnTech battery.

    that's got to be one of the oldest installation feedback for 12v motorcycle LiFePO4.

    any chance you could post pictures showing LiFePO4 model number and motorcycle?

    The TurnTech battery in the '04 KTM was one of the original 5Ah versions and the TurnTech battery in the '08 KTM is one of the earlier plastic encased 5Ah versions. Rather than trying to warranty replace the defunct Shorai LFX 14 in my '09 Beta 565 RS, I replaced it with the latest TurnTech 5Ah battery which now has the same dimensions of the stock battery. The reason I didn't go with the TurnTech originally is that at the time the available battery wouldn't fit between the Beta frame rails.

    Been using the 14ah Shorai in the 990 for sometime now with zero issues.

    However, long story short I pulled the perfectly working battery out and when I reinstalled it, the starter just clicks clicks clicks. Lights come on, fuel pump cycles as normal, all fuses good.
    Just won't start.

    battery was completely discharged while out and I had to charge it with a solar panel.
    Battery reading 13.4v now

    Either the battery is fried or the starter? :dunno

    more info is needed .. at what temps do you operate LC8 at?

    what's the exact model number? Shorai LFX14 ranges from 1.4lb to 2.3lb or about 3AH to 5AH actual .. not 14AH .. pq/eq means little to nothing. same for CCA numbers.

    you need to measure bike's parasitic drain so you can figure out how long bike can sit without draining battery to dead. use 3AH to calculate from until you post actual weight of battery. please also post voltage measured at battery 3k rpm and idle. it's important to use a known to be correct meter.

    to determine is your LiFePO4 battery is still good. charge with any full size PB charger without desulfate mode (not a tender). 12v LiFePO4 reaches full charge at 14.6v ..

    then allow battery to sit overnight. resting voltage should be 14.25v range .. at first current draw .. voltage will quickly fall to 13.3v .. this is completely normal.

    then start your bike for the load test ... if resting voltage is 14.25v then starts your motorcycle strong .. odds are your LiFePO4 battery is fine. if LiFePO4 battery resting voltage is 14.25v and starter only clicks. then you don't know if battery is dead and/or starter relay/starter/key switch, bad connection, etc is bad.

    report back for next steps ...

    13.3v (90%) when putting your bike away for the night is the desired voltage. don't allow your battery to fall below 12.85v (20%) for max life.

    Thanks! I'm going to put it on the charger as soon as a confirm the non-desulfate issue. 13.46v right now @ about 45F in the garage. Maybe the 13.46v is not enough juice.

    if 13.46v is for Shorai LFX14 taken resting overnight ... that's about 92% full and perfect voltage for starting. just off the charger at 13.46v is not fully charged. resting voltage is what's needed.

    use this chart for state of charge by voltage for all 12v LiFePO4

    :rofl:rofl:rofl:drink:muutt:dunno:vardyBased on my research of cy's battery thread, I ended up buying the Shorai LFX21A6-BS12 which has served me well since installation on 09/12 used in both my DL 1000 Vstrom, and TE 610 Husqvarna (and this battery is still going strong) . . . . . . Although I've rarely ridden in sub 35F temps, but many starts in the low to mid 40's.

    Most posters have stated that they're using the Shorai LFX 18 . . . . . . . . .

    So my question is, any inmates using this sized LFX21 Shorai battery with good results in the 990 ? ? ?

    I tend not to ride in freezing, or sub-freezing conditions for obvious reasons . . . . . . :vardy . . . . :dunno . . . .:loco . . . . . :muutt

    . . . . . :drink . . . . . :rofl:rofl:rofl:1drink:rofl:rofl

    Anyone ? ? ? ? Reason for asking- Just picked up a new-to-me 990 . . . .

    Thanks.

    Just found this thread.. and have been running Shorai Batteries for nearly 4 years now. 3-4 batts in my different engine configurations KLR 650/705's, a 530 and have a friend running one in her Duc 750 Monster.
    Ran a lightweight 1.5 LFX14 for a 25-30,000miles back in 2012/13 while running a 705KLR with high compression, kick start conversion and stage two cams, then when I killed it with a voltage drain over the winter went up to the 2.3lb LFX18L1-BS12. Still going strong now.
    Also put a LFX18L1-BS12 Into the 530.
    Am now picking up a 990 and will be deciding what I can stuff in there, when I get a chance to measure up the battery.

    Customer service has been OUTSTANDING! I've lost 1 in my KLR due to letting it get drained to zero in the cold and she lost one due to a bad R/R. (Put a Roadster Cycle Mosfet in it then, already have one in my bike). They replaced them all no questions and had much info as we were trouble shooting. I do use their charger to keep the batt up as even my Vapor will leak some voltage and take the battery down if I leave it sit a few months. As long as the batt's are up to snuff I've never had any problem starting in any temp.
    Have done several multi month rides across the country and never had one leave me sit. Only time they have crashed is when drawn down over the winter if I'm not riding my bikes.

    Anyhow my main reason for replying is do you have a LIST of ACTUAL AH ratings for these batteries?
    So that we can do a better job of spec'ing out the choices.
    Thanx a bunch,
    Jim

    Can add here also:

    Since the battery was dead in my dads 950 I moved the heavy lead battery from my 990 to his bike. And finally got around to trying to boost my old dead Shorai back to life.

    Had it go to low cause of bike standing to long with a current thief. Thought it was toast so just threw a lead battery in it.

    Have since read that Lithium batteries can be brought back to life. Have been sitting in a box for several years, showed 0.0 Volt, did not take a charge at first but left it and it started accepting power:

    Installed it in the bike and gave it a try:

    Running the Shorai LFX21A6-BS12 on my '12 990A. Steady 14.4v charging with new FH020AA VR.

    Great results so far although a slight learning curve this past weekend in NJ with temps hovering around freezing overnight. Pre-ignition lights on, grips on the voltage started climbing slowly from 12 to 12.4v. After the third attempted start the bike fired right up, quick and clean.

    The clock did reset itself a couple of times on the early attempts, saw the voltage drop quickly to 8v then back up on crankover. Might leave the pre-ignition cycle go a bit longer to avoid false starts next time.

    I have had a Shorai in my 2007 990 adv, and 2009 690 Duke and have had no issues at all. The only thing I have been looking for is if anyone has ever made a "quick connect" for their adv. I would like to have it on the charger just dont want to take my skid plate on and off everytime I wanna throw it on the charger after a ride. If so what did you use?

    Mine has something like this: http://www.ebay.com/itm/2-Pin-SAE-1...ash=item1c464033b3:g:iPcAAOSwnDZUF0Et&vxp=mtr

    The wire from the battery has been zip tied to the crash bars.

    Might want to look for a little bigger gauge wire and fuse if you'd want to run accessories of it.
