Hi All. hoping for some help here. I just picked up the Bonza Mech Tube. I am currently running two RDAs on it. the Bonza with a 0.18ohm build and a Drop Dead with a 0.24 build. with both these builds I am using the 40T batteries. the issue I have is I am getting Hot Button issues with both builds I have calculated that I am in the Amp range of the batteries. I have cleaned the thread and the contacts. But still keep getting a hot button. Any advice as to why. I have the stainless Bonza. Any advise will be helpful to resolve the hot button issue. thanks in advance to the great community.
