Hi guys, previously my set up is 6v with normal 510atty, this works fine, not much leaking issue, even if there is probably only 1 drop out of the whole tank. Lately, i'm testing 510LR with 3.7v setup, i kept getting my collector tank filled with leakage from the center connector (i think it's because too much liquid getting into atty, i tried to give the control ring in the atty connector a quarter turn but doesn't solve the problem). My question is, is it necessary for AFS or AVS to run at 6v and above to make this work properly?
