    ok so my batteries are a few years old now (stock lead acid with a Shorai LFX36L3-BS12 in parallel) and are due a replacement. neither battery is good enough on its own but together they spin the starter like a mother.
    i could do with a smaller 2nd battery to free up toolbox space, or even better just one battery.

    what battery, or pair of batteries, do you guys with high comp/aggressive cams/strong valve springs engines use?

    thanks.

    the antigravity YTX12-24 battery is quite expensive, not something you'd take a chance on.
    so it starts 240hp bikes no probs, on its own? even in the cold?

    Stock Yuasa started my Carpenter bike fine, for years, and it wasn't new. I did the starter and ground upgrade, though.

    THEY use that battery in cars so Im sure its going to start your bike as we used the smaller litium battery in other bikes and they worked great . and you want to use the heavier cables . we use the stock starter

    Expensive compared to the cheapo lead acid $100 batteries but $400 is not much for a permanent fix and they last twice as long and has more than twice the power of the stock battery, weigh only 5 lbs and frees up all that space under the seat . I watch my alcholic friend spend hundreds of $ on booze and strippers daily and he has to push start his hot rod zx12 because he wont buy the battery he needs to start his bike LOL He just blew up his new $ 8000 Carpenter engine because his ecu is toast and has no rev limiter and only $150 for a used one ? We use 2 lithium batteries in the TRIUMPH STREAMLINER

    Just FYI -
    I went searching and found a bunch of bad (1) reviews on Amazon regarding this battery. :(

    Most 1 star Lithium battery reviews are due to user error, it's not a lead acid, so don't treat it like one...

    A good balance charger 2 or 3 times a year will keep a Lithium battery good for years and keep it performing far beyond a lead acid. FWIW I have a little 1 pound 12v LiON battery that can start my Daytona 955, even in cold, subfreezing weather.
