It's been a while that I'm developing a camera control board and its software. That takes me hours sending commands for testing it on long shooting sessions. There was no battery enough here for such amount of tests... until now! ;)

Some time ago I've noticed a small hole on the battery slot of my S95. It is protected under a flexible rubber stopper. Well, then I decided to improvise and build an external battery adapter by hacking an old worn out battery. Two 3D printed plates and a female JST are now replacing the cell. By that way I can use external sources like bigger 1S Lipo batteries. Here go the images. It's quite simple, but very effective.

Battery tear-down:

The white plastic base was cut to be the female slot. The female cable was soldered on a little embedded circuit which has the contacts of the battery cage. A 3D printed core was build as two identical pieces:

That's it! All the parts was glued with CA.

Now I can use external 1S Lipos or even a DC source who will give me hours of work with no interruption. =)

Note: If you will gonna do that, do it at your own risk. Here is working like a charm.

Here is the STL object. for 3D printing: Adapt_Battery_S95.STL

Cheers,

Sandro Benigno

Nice one. Thanks for sharing this battery hack power extension.

how are you controlling your cam ? CHDK or sending commands by canon serial console ?

Excellent! I wanted something like this for a long time. Haven't had time to work on it. Are you willing to make the 3D files available?

Interesting solution. Competite w original CANON ACK-DC60 adapter =)

@Eduardo: full control under a protocol. No just pulses or so.

@Simon: the 3D file is already there linked after the latest picture.

@F1P: Yes. The plus here is that the internal circuit allows me to recharge the external Lipos, by using the standard S95 charger.

Sandro Benigno 54 minutes ago@F1P: Yes. The plus here is that the internal circuit allows me to recharge the external Lipos, by using the standard S95 charger.
And some bucks savings - 50 or so. =)
Unfortunately canon now remove external power connector from all "compact" cameraz... =\

Sandro, nice tip that you can also use the standard Canon battery charger for this hardware hack. I am planning to do this hack for Canon sx260HS camera which is also using "BATTERY PACK NB-BL".

Excellent! I have been interested in a way to do this but now I won't need to! Great job.
