I'm making an extremely simple circuit with an LED, a switch, and some batteries. One of the problems I'm trying to solve is how to best join two batteries in serial with wires on either end.
I want to use 1.5V AG10s (aka LR1130 aka 189) because I can get eight for a dollar at the dollar store, but I can't seem to find a manufactured holder for them.
I was making a stack with a wire, two batteries, and another wire all wrapped in electrical tape (simple enough, right?) but sometimes it comes apart. Any thoughts?
