Can someone tell me please what the ‘error indication’ thing is about? I have just got 4 x 18650 Protected Panasonics and that is all I want to use a charger for. I am looking at this charger review and also the SysMax/NiteCore Intellicharger i4 V2 charger review Review: SysMax/NiteCore Intellicharger i4 V2 Charger .
EDIT: At the moment don’t know if I will be getting one 4 cell flashlight or two flashlights taking three cells and a single cell each.
