When you read the data sheet correctly you can see, that the distance between the pins is different for a AA and AAA battery holder. That`s why I was asking if somebody can recommend a holder that fits.
@fets So far, I have only built the 5x5 board (but the others should be schematically identical). The only issue I have found so far is that I cannot get the ISP port to work. But I have checked and I have an identical setup on the 1.0 board and that worked, so I suspect the programmer is too weak to drive the net on this one. So it is not a board-issue per se, and might only be an issue on the 5x5 board as routing is the most complex on that one due to the size.
@Nca78 said in Dimmable LED kitchen light (Arduino, APDS-9960, RGBWW led):
Do you use a relay to control the leds or still a MOSFET ?
i'm using mosfets.

Both need protection (internal or external) from excessive discharge (or excessive charge, and short circuits etc)
That is where our new library to check battery level goes in, we could dream to have an internal mysensor security check of a LiPo battery ! they do so in 'copters
I may pass on that. I'm not used to software glitches having quite so much potential impact, and I don't need to save every gram. But to each their own!
