18650 Battery Holder
Holds one single 18650 battery. The 18650 is a very popular rechargeable battery these days.
We can also fit 2 x CR-123 batteries in this holder. CR-123 lithiums are 3V each, thus 2 of them in series will give you 6V. This becomes very cool as 2 of this 18650 battery holder with 4 CR-123’s, although not rechargeable, will give you a nice 12V battery supply.
This is a sturdy holder with a tight battery fit so that they will not easily fall out. It comes with leads for easy soldering and connecting to your circuit board.
