I just recieved my new DSE 905 v4 yesterday and the thing works great so far except when using a 510 adapter with a LR atty, This worked fine at first but after an hour or so the LEDs would start flashing after only 1 or 2 secs of inhaling like the batt is dead. I then switched back to a 901 atty and the thing works fine. Just curious if anyone else has any experience with a similar setup. I dont have any normal 510 attys to try yet. I should be getting a couple in the next day or so and i will try those. I hope this thing can handle the LR attys as I have 5 brand new ones. Any help would be great thanks
