Has anyone experienced a loose battery with a EHPro Caravela clone? I have the medium sized pin installed (larger one was too long) on the 'vela, a Yeahsmo Crown rda, and an EFest 18650 Flat Top battery. It's not firing accidentally but if I jiggle the mod just a tad I can feel that the battey has a few mm's worth of play between contacts. Any help would be greatly appreaciated as I'm using my mechanical mod for the first time tonight and although not a deal breaker, it is becoming quite annoying.
