I am a newbie here and despite my looking all over, I still haven't found any real answer to this. All I have so far are 18650 and 26650 batteries (protected versions). My Xtar SV2 may well be the best device for such a dummy. It's really easy to use and I think it's impossible to do anything wrong with it. But still, other chargers like a VP2, a VC2 Plus Master, or a Lii-202 with their different offers on the display seem to be more talked about. What am I missing if I have to stick to % readouts? As a backup and/or a competitor to my SV2, which of the above chargers would you recommend?
