I just received four Vapcell F12 button top 14500’s. They all arrived at 3.75 v
They do in fact appear to hold about 1200 mAh worth of juice, and the internal resistance is a remarkable 53 to 64 mR. The only possible downside is that they’re pretty long at 51.4 mm. They fit fine in my SP10pro and Skilhunt M150, so it’s not a problem for me.
