Hi Alex,

They also may be a curse.... as Lithium Ion batteries will give of some heat, certainly during charge, but also during discharge (use) which in the extreme, say with long runs, lots of images, lots of screen or live view or video use might heat the image sensor slightly and thereby increase noise in the image.

It's something which would be good to quantify by experiment... Image noise, say taking a dark (image) using the internal camera battery versus using a plug in external power adapter to the camera. To really test it, the battery should remain in use for a while and to be fair the external power soucre as well.

BUT The above is only really relevant for a DSLR or a device with internal batteries, not with USB powered webcams or astrocams that were discussed earlier in the thread

Best
JA
