The Shorai LiFeP04 for the R3 runs 285 and that's no prob if you need those CCA. All I am saying is there is an economical way to reach "balance" for most of us guys with 7.8 to 1 compression and big flywheels.
I spent 81 on the East Penn Batt(Dela/Big Crank) 310 CCA AGM and that left enough coin to pay for my whole rear tire at 157 and my EBC brake pad replacement. Now I could afford the Shorai but do I need all those CCA's at my low compression high stress marraige? Probably not. I admire the guys that have the setups that require these. Being new to the 07 Rocket...it is a initial financial black hole...Tires, brakes, battery, insurance, mechanic and my bike is not high performance so I have to find deals where I find them to do more maintenance than I would if I dropped 300 on a battery.
Not saying LiFeP04's are not a paradigm shift in battery technology-just you got to pay to play to get the CCA and weight savings lost to half of us R3 owners that can get by on a 80 dollar QUALITY battery.
That SHorai cost more than my new set of Tires so till I get up to date on maintenance I have to strike that balance and the Deka ETX-20L does that for me.
Ride safely guys!
Cheers...Greg
PS...The oil change on this bike cost more than my 62000 dollar Infinity Q70...so you know somethings up!
