I recently got a Shori or adventure power as there called now. Deffinatly not the cheapest but with the huge weight saving, the power and fact they will hold a charge for over a year without use of tender I was sold. Happy as of now!
Thanks for reminding me to check the charge level.
Have had a LFX18 Shorai battery pegged for use in my RC51 sitting on a shelf since March 2012.
I checked it just now, and and it's still maintaining 13.33V, which is only .01V less than in March of last year, when I received it.
As long as there are no power taps current leaks, these batteries hold a charge for a long time.
The exact same model battery as been in my FZ1 since last year, and it has held up wonderfully. Still spins the engine over quickly.
Since they use different technology, when it is cold outside, it is suggested you switch the key on and let it sit for a short while with the headlights on before starting the engine.
I didn't bother during the mild winters here in Florida, and the bike started immediately.
Since they weight so little, I suggest buying the largest capacity model for street or even track use.
For my FZ1 and RC51, I went with the 18Ah model. It only weighs slightly over 2 lbs.
