Were you able to put in a pushbutton switch or did you decide to just use the on/off slide switch that it came with? I only ask because I know how cramped that 2x AA box with 2 14500s is, we want details ^_^
Yes, parallel (thanks)
This box didn't come with any switch, I added a tactile switch.
The battery on the right gets turned around. Then run ground from the bottom to the atty adaptor negative.
The tact switch is located above the left battery, neat thing is that one side of the tact switch is close enough to the (left) positive battery so you don't need a wire.
So...left batt positive to the tact switch AND to the right batt.
Both batt grounds are already together. Then FROM the tact switch to the positive on the atty.
Hope that makes sense?
Vapes real nice, with the 2 batts seems like it just has a strong "steady" 4 volts. I always swore by 6 volts, but I like this too, and elliminates the intermittent burnt taste.
I put it on my (SE) USB charger, used a rubber band to push the tact switch in. Red light is on...lets see if it turns blue.
