Today, somebody asked about this S4’s capability to make proper positive contact with a flat-top 21700…perhaps also to other flat-tops. Remember when even the SkyRC MC3000 had contact issues with flat-tops too? Yes, this Vapcell S4 does make positive contact with the 21700, and all my other flat-tops. See why in the photos below: (edit: I just checked, my Miboxer cannot also make contact with my 26650 flat-tops too!)

The Samsung 21700 inside the bay still has plenty of room to spare, up to 75mm.
People who are familiar with an Opus BT-C3100 will have no problems handling this one
Yes, I’ve won the Vapcell GAW.
Like it or not: it beeps when a task is completed. Which is (very) fine with me.
Wow, it has a bell tone which is usefull as a reminder…I usually need this kind of feature becos, sometime I get busy and had to tell my nephew to watch over. With bell, it will be easy and never had to explain long stuff above charging battery…keep things short, when you hear a bell, it full and pull them immediate…
Wuben A21 Apollo. Tested. The original cell is 74.6 millimeters long. I added a magnet 2 millimeters thick. The tail can be screwed. There is still a small margin.
