small NiMH battery charger. is it possible?

[EliasJonsson]

I'm in need of a miniaturized NiMH charger circuit. The circuit needs to fit within a 45 mm * 11 mm rectangle.
The circuit will need to be able to sense when the 2 NiMH batteries are full, automatically cut charging power and to the user indicate full battery via an LED light.
Supplied power will need to come from a USB-C connection, 5 volt.

Is this even remotely possible to achieve?

Hello,

@Martaine2005 , the image does not show.
It seems to be from this page:
https://www.ebay.co.uk/itm/252804309711?ul_noapp=true
The shown charger is for 1 NiMH, the TS wants to charge 2 NiMH batteties.
This is one for 1,2 or 3 NiMH batteries:

The size is 30 X 15 mm.

Ah yes. The link was to show the size is possible. Also much smaller.
You just have to search and read the description.
You can also find 2 or 4 cell chargers that you can cannibalise for the PCB.

Whoa, that might just be it! It might just fit. Thanks a bunch!
One step closer to production of my electric clipper to come.
