From what I hear, the Shorai is hot enough out of the box to crank your bike.
Every biker should own a Variable 2/12 & Higher Amp Batt Charger.
I'll use my 2amp for my Shorai before it swap it for the HEAVY Stocker.
You should never hit a motorcycle battery with more than 2 amps... it will warp the plates almost instantly.
