Noticed that when i charged an 18650 and an 18350 at the same time in the intellicharger i2 the 18350 charged ok but the 18650 did not charge and just got hot. i had to remove 18350 and just leave 18650 on its own to charge it. was wondering what issues there would be with charging an efest IRM 26650 @3500mah? Thanks...
