I have two box mods both 3.7 14500
both work with the tank and now only one works with the tank
yet the one that no longer works with the tank will run a 2.0 cart and any attomizer just fine
the carto in the tank is a 1.5 and I cannot understand why it wont work on both box mods all of the sudden
the black button box is the one that works on everything but the tank
the red button box works on everything
both are made of identical parts
