One way to use (connect) flat-style camera/mobile batteries

One way to use (connect) flat-style camera/mobile batteries.

We probably all have quite a few of these; and they are ideal for use in mods, although some of the wider ones will not fit into the smallest NicoStick box. But my Samsung camera batteries do - just

The ones I have are all 750mAh, which is great, and the size and slimness is good too for box mods. But how to connect them?

Here's my solution ...

I don't see myself using this method to build a mod but it is very good information to be aware of just in case I ever have to MacGuyver an ecig while I am on the go.

I carry a spare cell phone battery in my wallet.

Thanks a lot,

Looks hammy, but works well. Can get a very good tight springy contact. And with little extra space taken.

Another way would be to use a mounting board, with two small screws with the heads making the contacts and a spring or some foam at the other end.

Here is such a battery in use :

Kinabalo, its amazing what you can do with a paper clip, you are MacGuyver there is no doubt about it....


Cisco...

Very, very clever paperclip work, kina. And I love the touch switch. Did you cover that in a thread I missed?

Edit: Duh, found the thread two seconds after I posted.

thats a very clever idea

Adding a couple of notes:

Probably best to make the contact bit first using some narrow pliers and then then with this held tightly in place bend the long eires around the other side of the battery; then take out battery to bend the wire more fully into position.

Once made the connectors can be reused; i.e. one can replace the battery after recharging; reconnect by putting the contact end on first then prising the other end over the battery.

Version two.

The battery sits on a board that has a second layer at one end (joined with wood glue/resin). A piece of highish density foam is used as a kind of spring that the battery can push back against, allowing the two connector arms to snap over the battery to make electrical contact. Had a nice vid of this with a great 'snap' sound but my video software is down So pics only. The foam could be glued in place.

The arms fit into 1mm holes made with a drill; slanting backwards to will not come out.

The pics can fill in the rest of the details ...

Very ingenious - i had also thought camera / video batts would be perfect but no way to attach them...

kinabaloo .... you amaze me Watching the things you make is always fun, entertaining, and educational! I really like the fact you use a breadboard for testing as well!

Breadboards are great!

Just a few things don't fit well - relays, power/rectifier diodes and most preset pots.

'Entertaining and educational' - maybe i should ask for a tv show

These batteries certainly work well - at least the one I've been using. Though it might be a Li-poly or something but checked and it's just a Li-ion. So sometimes size does matter (max output current / internal resistance).

A customer might be surprised by paperclip battery contacts (eek) but they do the job well. Nevertheless, I have some 14500s on order to compare.

Yeah, that's what we used when testing diodes/resistors ... Take all the work out of having to solder everything

your own tv show ... ya never know!
