I'm making my mintyboost V3 from scratch, meaning I'm looking at the parts list and buying all my parts separately. I'm going to be adding in two switches; one in between the battery lines to prevent idle draining, and one in between the data lines to short them if need be.
My question is: is there anywhere I can add an LED to indicate the batteries are connected? I don't want any loss in current, but I also don't want to accidentally leave the power on and have the batteries slowly drain without charging anything.
Thanks in advance.
