I've been wanting to ask this since I was interesting in using homemade battery packs like 6 D cell batteries soldered together. I realize that this something that would give 9vs, but the amount of mAh would be greatly higher than any 9v could do. Would such a pack be safe for small electronics like this? https://www.aliexpress.com/item/32408914467.html?spm=a2g0s.9042311.0.0.4cbb4c4dA2eSPh
Someone told me on a project I made using that RF switch that I should invest in a Li-On battery since they are small and can provide a good amount of electricity for most small projects, but I want to tinker around homemade battery packs of various sizes before doing that.
I just want to make sure I am not overloading anything else will still providing ample power. I'll be buying some cheap alkaline D and C cell batteries to make some packs and see how much amps I can get out of them.
