    anyone got a reliable battery recommendation that would still fit the oem battery holder with this here “deep” tool tray? looks to me like i need something dimensioned as described in the header. my current one runs “longways” (7” front to back) and wouldn’t work unless there is something creative i am missing (width of tray left to right appears to be 4 1/2”)
    i scored it recently and would really love to use it but i’m not totally crazy about relocating the battery somehow.

    25.4 M&M's to the inch.

    Fewer if they are peanut M&M's.

    awesome thanks. that’s what i get for measuring in space. that saves me a big hassle.
    here’s an unrasterized version. looks like i should be good to go with one of the shorai’s...
    https://shoraipower.com/battery-specifications
    (seems like i need 115mmL x 140mmW x 180mmD give or take [4 1/2”W x 5 1/2”L x 7”D])

    hey man. can i just ask what i should be looking for here? is there a Cold Cranking Amp rating i don’t want to go below? some of these seem to be significantly smaller and weigh a pound (or more?) less in some cases.
    do i want to just get the correct height and largest CCA rating and call it a day?
    or is there a good opportunity to lighten the load on the GS by getting a smaller and lighter battery?

    Jon--

    The Odyssey PC 680 is listed as having 170 CCA (cold cranking amps), that is more than sufficient to start an R100 engine in reasonably good tune. The Shorai case size #5 battery is listed at 210 CCA, so it sounds like the Shorai would do as well as the Odyssey and do it for even longer.

    I think the rub here is to keep the bike in fairly good tune so it isn't necessary to repeatedly crank the engine, which tends to heat-up the starter which isn't conducive to a long life for the starter.

    Battery technology has come a long way since the slosh batteries that were standard even when the R100R & R100GS were the last of the Airheads. The sealed gel cell batteries like the Odyssey are an obvious improvement if only to eliminate the venting the acid fumes which is corrosive to the adjacent metal pieces. The Lithium ion batteries are yet another newer generation of battery technology delivering essentially the same reserves in a much smaller package.

    thanks. so if i find a shorai at 170 CCA and it’s smaller and 3/4 lb lighter i just make a call as to whether the shorter height works...?

    If the shoe fits . . . or rather, if the Shorai fits.

    or simply, yes.

    That Odyssey 680 will out last three of those Shorai batteries.

    er. can i /stand/ up that PC 680 so the connections are on the right side of the bike? would have to relocate the mini busses i have on there but is that a workable option...?

    I believe that tool tray is from a Mono, think the battery orientation is completely different to your Gs. Maybe it might pay to see if you could alter the battery tray to give yourself the room. Have a shorai in my cafe. Been a bloody good battery so far.

    If you already have an odyssey, I don’t think it’s the battery that’s the problem so much as the battery tray.

    Get one that fits the odyssey and that tool tray should fit...

    thanks man. so when people say “mono” are they referring to the g/s or something? i’m missing that apparently. if so, they just call the GS or PD, GS or PD?
    for some reason i think it was listed for the GS and it seems to fit fine (excepting the battery) but i haven’t pulled the battery yet.
    you are saying that i might be able to get a new battery holder assembly or chop this one up a bit and keep the odyssey i guess?
    or i guess if that’s too much i’ll spring for the shorai...

    Monolevers had a battery box across the frame, sized for a narrower battery like the Odyssey. Because the paralever is longer than the monolever this left enough room for a bigger 25Ah battery placed lengthwise. This is what the GS has, but you can buy aftermarket battery trays that go across the frame like monolevers had, which leaves room for your tool tray.

    Here's a pic:

    Your toolbox would've likely been a perfect fit for the hole left by fitting the battery mono-style across the frame.

    ok. /thanks/. i’m a little slow on the uptake on this one. so i can find a “monolever” battery holder and use the GS fittings to hang it is that right? what year bikes and model am i looking for? any year g/s? i realize now that this (or modifying mine) would really be the best solution since i won’t have to find a specific shaped battery if replacing on the fly....
