I saw my mistake, confused the 123's for the big chuck.
Three different batteries I need. Want to be able to vape big chuck with both options plus a couple sets for the little chuck.
I am jotting this stuff down, might just print out a bunch and going to take it to the battery store.
I basically flunked the battery class here. Probably have a D+ going in the atty class.
Someone should put together Chuck Kits for Dummies.
Buy this package for 6.v -list exact battery, make and model along with charger make and model along with recommend atty
I know they have been listed but when I go to the dang website I get more confuddled because they ask about chargers and spacers etc.
Buy this for 3.7v.....
Buy this for little Chuck.....
and then don't let anyone add comments about changing stuff or multimeters or ions and tenergys and aw's and maws and so on....
I am trying but I just cannot get into the whole battery thought process.
Usually I am not this stupid but when it comes to electronic stuff, forget it. When it comes to batteries, I can stick them in and turn on the switch...if I can't get it to work after that, I throw it, cuss like a truckdriver and get myself a new device.

I am taking my notes and going to the battery store, won't be in stock but they are local enough. Hoping the dude behind the counter knows his stuff.
Edit to add: I understand which sizes, that I need 18350's at 3.7 for LC and 2qty AWcr123's for 6v and an 18650 for 3.7...it's all the other stuff in regards to brands and types that has me so conFinfuddled.
