thought I killed my Shorai the summer 2011 and the Voltage was 9 V only. Since the Shorai charger at first effort did not bring it alive I gave it some chock treatment with my automobile battery and then filled it up with the Shorai charger. Worked fine ever since. Anyway I find now a year and a half later that the charger wont fill it more than 14.0 Volt and I'll buy a new Shorai this winter. I'll never buy any cheap lead/acid batteries again since these may be everything from just fine until dead from day one. No more milliondollar YASA either.
