5v with a 901 atty interest me. I been using 510's @ 3.7v works great much better than the 901's @ 3.7v. I have about a dozen 901 atty's and really want a unit I can use them with. I would like to hear from folks using 901's @ 5v with the XHaler.
901 @ 5v is awesome. I wouldnt get the 3.6v batteries, very weak using them single with spacer battery. Using 2 3.6v batteries will just blow any atomizer on my Xhaler. 5volts is pretty awesome in my opinion, though this is the first mod ive owned so 5v is blowing me away.
The 901 even seems to work ok with two 3.6v batts and the cap screwed in but you have to keep the button time down to 1-2 seconds. I have not burnt up any attys yet.
I have been running almost exclusively the 901 at 5v with my Xhaler. I have been using a cart too. I top off with 2 drops in the cart and 2-3 in the atty and that lasts a little while. I have had no luck running the 801 with a cart but dripping is ok. The 901 even seems to work ok with two 3.6v batts and the cap screwed in but you have to keep the button time down to 1-2 seconds. I have not burnt up any attys yet.
