How do you guys house your 2x CR123A setups?

I decided to go the route of 2x CR123A's to power my project, however I'm unable to find a premade case or box with contacts and leads. I see tons of "storage cases" when I search so its a bit hard to find if its out there. Just want something like the many 2xAA, 4xAAA, etc, style packs I see at radioshack.

I am going to house the entire project in a small project box, so I'm not totally against attaching the batteries together permanently and basically making my own "pack". If I do this I would have to make my own charging setup, which I would assume isn't too hard to do?

How do you guys normally do it?

Personally I have never seen them before... But I'm sure they're out there...

Personally I would go DIY. Grab one of these...

And mod it with contacts on the inside of the container. I would solder wires to a small piece of metal then hotglue it to the inside of the container.

Just a suggestion...

Just get an 18650 case. They are in series, right?

Yes they will be in series. Is the 18650 twice the length of the cr123a?

To find out the length of your batteries in mm's, take away the 0 from the end, then the first 2 numbers are your width and the last 2 your length, cr123a's are 16340

So, they aren't double, but pretty close.

^yup!


i use these to connect my buck driver(s) to my power supply when using a test load.



if they are protected 16340's they will be longer, you can compensate by cutting the spring down substantially if 2 of them wont fit in or remove the protection circuit.
