Long thread so havn't read it all yet.
What I do know is I have seen these shorai lightweight batteries fail at the track. They are intended for track use and still they fail or loose charge.
What is more of a problem is you CANNOT charge them without the Shorai special charger.
That = no go for me on a touring adventure bike. Is there more to the story? Can I get the cliff's notes version?
Ride more, bark less
