Ack! Eric, I sent you an email, but I'm going to post here as well.
I just placed an order for some stainless cartos before I realized they were prefilled. As you probably remember, I don't like the prefilled.
I hope you can cancel that order for me before you get it packed up. Or... if you happen to have any unfilled stainless cartos you could replace with those and go ahead and send the order.
I emailed you, they are empty

I'm going to try to take one of my old GoGo
batteries and make a USB pass
through. It should be fairly easy (in theory). I'll let everyone know how it goes... or if I burn my house down.
it is... but takes some patience. it really only needs the black and red from the USB cable, remove the battery (important), drill a small hole for the cable,
thread it through, solder the red to red and black to black from where it was on the battery and is now loose NOT on the circuit board. tape or use the liquid electrical tape stuff on the solder points and on the drilled hole, put it back together, let it all dry... works like a champ. I made one way back and posted a pic in this thread somewhere ...
One of my GoGo batteries is acting weird. When you push down on the button the led lights up but no power is transferred to the carto. If I tap it or play with it a little sometimes it works. It seems to me that it is maybe a loose wire or maybe a bad solder joint on the circuit board. Anyone else have this issue? Were you able to fix it? I bought the battery in Aug. and I rotate 2 so it's not an end of life issue. Unfortunately, I only own 2 batteries and no backup system so I will have to wait 3-4 hours while my other battery charges before I can vape again. I guess I'm going to be shopping at Eric's place today.

As others have said, it is most likely your connector on top, the center post. An eyeglass flat head screwdriver works perfect for this. I do it all the time and it's second nature, just prop one side up a tad. (not too much)
The vaping Gods have not been smiling on me lately. I have a couple of Chopper's tanks and less than a week ago I put a brand new carto into the tank, filled it and was happily vaping for 2-3 days. I was going away to upstate NY for a couple of days so I filled it with juice and it was fine the first day but the next morning it was tasting very bad. 4-5 days on a new carto, I was using BWBs Applewood. I was getting weeks out of a carto before I needed to clean and rebuild it so I don't understand why this is happening?

Not sure but it could have burned a bit? I like to draw in when I fill them before I fire it, it pulls in liquid to avoid this.
I have a SuperTanker (15ml tank) that I made and I can't get two full fills out of it without it tasting funny... at least not yet. But 30ml is like filling a standard go-go cart about 12-15 times.
Hey Eric,
I couldn't help myself and ordered 10 of the gogo dual coil clear cartos from you on sat evening late. So I read in a previous post of yours that you discounted them for cyber monday. How do I get the discount?
I will send you two free on the next order (or equivalent stuff) , just remind me
