I'm Looking for a connector to use V4L Carts on my Ego batteries. I ordered one from goodprophets and it just doesn't work right. The adapter threads on the battery just fine....but when I put the carts on it goes on very rough. It vapes, but when I take the cart off the adapter comes with it and I have to fight to separate the two. Any suggestions? I'm assuming the V4L carts are an 808 connection.
