    Shorai Battery

    by JamesR » Mon Mar 11, 2019 8:40 am

    I'm looking at the Shorai LFX09L2-BS12 battery, but there's two options to choose from. What are people going with? I've got a 09 450x with only the air box mod, high flow air filter, JD kit and a Q4 Muffler. No engine mods.

    Thanks, James

    That is the exact battery I have in my 450X. It is 5 years old and going strong. Expensive but I never have to put a charger on it even if the bike sits of 6+ months.

    Same exact one I have in my 06 , been in there since 2011 ..... 8 years and still starts right up after sitting all winter , each winter , I did not even ride the bike in 2017 due to health issues and when I finally did , it cranked right over ..... can't ask for more ...... Though , if/when this one goes , I will get the next size up , the difference is I believe 12 amp hours instead of 9 and if I remember right , 150 CCa instead of 135 ... ;)

    Neil & Jim,
    This is interesting you get such good life as lithium batteries like to be charged to a higher voltage and when full to stop charging. That is why you should use a charger meant for lithium batteries.

    I wonder if that is why normal batteries don’t last in a CRF as the charging system puts out a higher voltage.
    What sort of charging voltage do you get at the battery?

    It starts,it runs,it gets to where all CRFs can get to without the valve or valve plate dramas

    I believe around 13.5v to 14.5v depending on the state of depletion at the time , it also makes a difference when taking a reading whether you are taking it right after starting , or after its been running for a bit , as the voltage is always peaked higher right after start up due to the amp draw from starting ... ;) 8-[
