Agree with everything FXRich said, but wanted to add my own 2 cents...
It sounds like you only have 2 batteries. I would suggest buying at least 4 more. You never know when you're really going to need those back-ups. When you buy them, make sure you mark them. Personally I would dedicate 2 batteries to each of the mods you have in rotation (mark them 1A/1B, 2A/2B or Eleaf 60wA/Eleaf 60wB and PicoA/PicoB or in some manner that works for you).
