I'm using Efest batteries so I took out one o-ring and put in the shorter post. Seemed to be a perfect fit, but I'm occasionally getting interruptions while firing. The switch fires on command--every time--but throughout the inhale, occasionally it appears I'm losing the connection. I took it apart, made sure there wasn't anything in the way, or something that shouldn't be there.
Any tips on this issue?
