The author of Instructables under the nickname mahesh_jo does not part with the Canon SX 540HS digital camera, which is powered by a NB-6L battery.
The CB-2LYE type of network charger designed for this battery is rather bulky and does not fit in the camera case.
You have to wear it separately, which is why once the master forgot to take it with him on a trip to Chandigarh. I managed to make just a few photos. Returning, he set to work on a new, miniature memory that can be worn in the camera’s case all the time and never to be forgotten. The master takes the charge controller board with the Micro USB input as the basis of the device. It means that homemade will be able to work not only from a network power supply, but also from a powerbank, PC, and even a USB port on the handrail of a modern bus.
Despite the existence of modern programs for modeling, the master first takes (not instead of using such a program, but in addition to it) for manual prototyping of foam and hard film:
Well, when it is determined with the shape of the case and the location of the board and contacts on it, it launches Tinkercad and simulates in it practically the same thing:
The simulation result is laid out here, and he starts 3D printing:
Glues the carbonized tape on both sides (so as not to unstretch) to remove the battery - it becomes similar to some types of battery compartments, for example, it is also made in the Imula RP-8310 radio.
Marks on the case the location of the pads on the battery:
It has spring contacts exactly there:
Installs the board in the recess intended for it and connects the wires to the contacts, checking the polarity several times:
Testing memory in action:
To prevent short circuit when touching a working board, for example, a metal table, it supplies the device with a removable plastic cover on four screws:
And finally, it shows its memory in comparison with the regular one. Which can now be kept and used at home and not worn anywhere. And the new one is to take with you everywhere in the case along with the camera.

Anyway, it’s always good when there are two things that duplicate each other’s functions.One has broken - the second will help out while repairing the one that failed.
