On the shorai website it says exactly that in fact you DONT need any special charger....just one without the desulphate modes that most are equipped with these days..along with various other get out of jail free warnings like we cant help you if you fit the incorrect battery.....ie too big too small, not lithium versus acid!
in fact i guess its just like their warning to always fit genuine timing belts...... oh no ive just changed the rear sprocket on my Hyper.....ive only just read in the genuine manual that not having it done by a ducati dealer could seriously endanger my life!!!
I nearly picked up on a typo / grammar error of yours the other day, then remembered you cry when that happens so left you alone seems you only allow one way traffic
