I'm thinking about making an accessibility gadget for my mother using an #Arduino. I need it to be portable. How would you go about powering it?
@EnaWasHere they make ready-made shields with a battery charger and a battery I think
@EnaWasHere maybe sth like this? depends how small/light you want it to be. I like socketed standard cells for ease of replacement https://vi.aliexpress.com/item/1005001671520246.html
@EnaWasHere there's probably ones with flat li-pos too
