Highest mine goes in F is 572. Cranked up my ramp up to 200 watts and still barely warm. When I googled TC people were talking about ohms law and all that jazz. I know ohms law but since I have 2 30A batteries am I supposed to add them together? So confusing. All I wanted to do was quit chewing
If you are running Sony VTC3 or LG HB2, HB4, or HB6 true 30amp CDR batteries, then you are pretty much safe running full open 200watts, regulated mods use Watt's Law not Ohm's Law, but the catch is learning what the lowest battery charge per battery is the cutoff voltage before the mod warn low battery, generally in the 3.2 to 3.5v range is this cutoff.
200watts/6.4v (3.2v X2 batteries in series)=31.25Amps each battery must provide as this will be the highest amp draw point with a regulated
Now, get the question all the time of "What is the best wattage for so and so atomizer/tank?" and "What is the best TC setting for so and so coil build?" etc. The answer is the same because each vaper is different, you adjust these settings "To You Own Taste Preferences", not mine, not your buddies, but "YOURS". This takes time to fine tune the settings to your flavor expectations, throat hit, and vape warmth.
Example, presently I'm running a UD Bellus RTA tank with a dual coil Nichrome 80 wire 24awg build Ohming out to about 0.8ohms, running on a Kanger Kbox 200watt set at 200watts in Nichrome Temp Mode @420F Temp, and it is a pretty cool vape because the coils can't reach that 420F temp range with the airflow wide open and the airflow is very loose, just a little tighter than my TFV4 Tank and Mutation X V2 Dripper, but flavor and vapor production I am looking for is there. Set the mod in to standard power mode at 65watts and the vape gets a little rough for me. Best way to tell if the TC if functioning the Fuchai properly is test fire it in 1 to 2 second pulses while watching the screen, it should show the voltage pulse width modulation and detected coil temp fluctuating, if neither is happening, the coil may be to low for the Fuchai to operate properly, try rebuilding the coil to about 0.2ish or try a Titanium Coil build.
