Has anyone got any idea what the maximum safe amperage you can push from a Vision Spinner 1300 mah would be? I have a 1.4Ω microcoil in a protank head. If I were to vape it a 3.3v it would be running at 2.4 amps, and 7.8 watts. Is this a safe level of current? If so, how high can the current (amperage) safely go?
