Box mod keep cutting off

[quynhwil]

I'm having problem with my batteries or 5 volt box mod cutting off all the time. Even when I'm using mad vape vv box mod it still cut off, so I turn the main power off and then back on it works again for 2 second then the same thing. I'm using 3ohm single coil cart and dual coil 1.6ohm cart from Madvape. I even use five different sets of battery that I use in rotation. Can someone help me PLEASE?

I have the same problem with the same symptoms. I am pretty sure it's "user error" since I have two vv box mods and 3 pairs of batteries. I get the same issue regardless of what combination I use. And I have tried all settings (low to high) on the vv wheel.

I have also noticed that this does not happen with a brand new carto. But it happens with cartos that work perfectly well on other devices (particularly the Mad Vapes e-Go pass thru.)

I will be interested in any ideas people may have.

What brand of batteries are you using?

If it is a battery issue, the most likely cause is the protection circuit on the battery.

I agree - this seems like I am tripping the protection circuit for the batteries. I have two pairs of Ultrafire 14500's and one pair of Trustfire 14500's. All of them appear to charge normally and test well above 4v when newly charged. Since I suspected that I was tripping the protection circuit, I have been careful to try to vape at a low voltage (i.e. wheel turned down). But this does not seem to make much difference.

As the other poster mentioned, turning the on/off switch back and forth yeilds a couple of seconds of vape. Also, brand new carto's work well for an hour or so. (I have tried both 2 and 3 ohm cartos.) After approx. 1 hour on a new carto, I get this issue. And the same carto works well for days/week or so on other devices.

Thanks for any thoughts.

I have 3 five volt box mod and two vv box mod, all of them does the same thing. I'm using trustfire and ultrafire batteries. When I put a new cart on it awesome but then it stop and reset the master power switch and then same thing. Hopefully someone knows what the problem is.

The only way I ever got around these cutting off is to use AW Batts. It solved my problems. At least for me.
AW 750Mah Black 16340's and the IMR red AWs 16340s.

The 14500s I use the Red IMR AWs and Black AWs too.

I've noticed ultrafire and trustfire batteries have a little different protection circuit. I've also seen cuts in the rubber insulation of a battery connector that has caused a short. Just something to consider.

Thanks for the lead. I will look at the battery connector insulation. But my guess is that my problem (and the OP's) is with protection circuits. (I have a little better luck with the pair of trustfires that I have.)

If anyone out there has experienced this issue and solved it could pass along a recommendation for an optimal resistance level for cartomizers, I'd appreciate it. I have been using Boge 3.0 and Boge 2.0 cartos.

Well, I ordered some AW yesterday, Hopefully this will solve the problem. Thanks for all the info....

Thanks Doots, I ordered some proctected AW 14500, charged it and vaping away. My vv and 5v hasn't cut off yet, Its been a whole day already. I'll even try my old cart on them too and they work. Thanks again for the advice.
