Yup that is correct... But here's the kicker, I got 2 newish batteries from the vendors right hand man who said" both are charged but I've been using this one today..." So after an hour use using one (say 20 puffs) I swapped batteries to check out the other battery(i was excited) and that was in use for say 2 hours(screwed in and say 15 puffs) then I swapped back and that's when it all went pear shaped...
