I'd have more faith in their AH rating if I saw some discharge curves at different discharge rates.
The increased AH rating really only comes into play when you leave something on inadvertently and then would like to start the bike (at that point it's a really good thing, but something I try and avoid by design).
I'm more impressed with the fact that they claim that these batteries can still crank the engine when they're in a deep state of discharge.
All their fantastic attributes rile my "too good to be true" skepticism.
But things change and maybe it's all that & a bag of chips, time will tell.
FWIW on the CCA rating:
CCA is defined as the amount of current in amperes that a battery at 0° F (-18° C) can deliver for 30 seconds while maintaining at least 1.2V per cell (that's 7.2 V for a 12V battery).
7.2 V is kinda low for our purposes assuming they use the same spec to get their 270A rating.
I really wish Odyssey would make a battery for the FJR.
Fred Harmon was supposed to do a 17F Shorai start yesterday, but hasn't posted back on how that went.
I'm sure if I bought one & had it shipped to you Fred, you'd get me some cold start data ASAP.
