This is an incredibly simple two cell 18650 Battery Holder. When someone thinks of 18650 Cells they tend to think of flashlights first, which is fair since that is what they have been primarily used for. However, with this battery holder you will gain the ability to incorporate 18650 cells into applications like robotics or prototyping by simply dropping one into this device and attaching the leads, that’s it.
Hi Elliott
Looks like in series from the pic (7.4V)
If it was parallel (3.7V) the springs and nipple contacts would be at the same end I think.
and the cells would be positioned in the same direction.
Be a bit careful here as some 18650 cells with built in protection are almost 70mm long and will be an extremely tight and almost impossible to fit without breaking or damaging something.
I have been told (by Core) in the past that all cells Core stock are 65mm long and will fir all the holders they sell.

That holder looks to put them in series, so the voltage should be 7.4V.
I hope that was before February last year, as we started to stock Protected 18650’s at that time and they will not fit holders made for 65mm length 18650’s. For the 65mm length batteries, you would be looking for These Flat Top Ones.
