    When I use the Primo Mini (20W in WC mode) until the "battery low" comes, I switch the battery and the tank to my iStick Pico 75W.
    Then I can still run the same tank at 20W for the rest of the evening ???

    What is the problem with the Primo Mini?

    Are you using the Pico in TC by mistake?

    I got the same problem with my primo mini. I can use the same battery in my vtc mini without any issues.

    I even put the artic fox firmware on the primo and it's the same problem

    It was suggested, in the evic primo thread to tighten the little brass torx screw on the bottom near the battery door. I tightened mine last night, and it instantly cleared up this annoying problem.

    Thanks, @nate77
    Finally, I found the right TORX screwdriver.
    I could screw it about a 1/2 turn down.
    And yes, it looks like it helped.
    It's great, but still, when the Primo gives up, I can still vape on a Pico for some time. The Pico still shows about 1/8 power left, but not for a long time, vaping at 35W/0.25ohm

    I wonder, if the screw will get loose again after some battery replacements ???

    Used a Samsung INR18650 30Q, 3000mAh, 15Amp, pink.

    Unfortunately, it was only wishful thinking.
    Same sh... again!
    Vaping 35W on .25ohm tank, the Primo says "Battery weak" and cut off. I've got approx. 5ml out of my 6ml tank.
    The Pico have still 1/4 - 1/6 power on this battery.
