Safe amp draw and voltage.

[H4X0R46]

Alright guys, so I'm looking into the Coolfire4 TC100, thinking about buying it. Now my question here, it says it can handle a max voltage of 7.2v and max amp draw of 30A. What's the highest I should safely go on both? If I use a 0.5ohm coil at full 100w (just to measure boundaries) it comes out to about 7v. Super close to the 7.2v max. Now, if I used a 0.25 ohm coil at 100w (again, testing boundaries here) I get only 5v, but 20A draw from a 30A battery. Is this safe? Overall question here, if I were to theoretically fire this thing at 100w, is it advised to use a 0.5 ohm coil or a 0.25 ohm coil? Thanks guys!

As this is not mechanical mod, the regulated APV automatically protects over voltage and current.
For example, when I use 0.5 ohm in my RX200S, I can't go over 150W although the firmware upgraded to max 250W.
So don't think about coils and just adjust your TCR and enjoy vaping

Thanks for the response! So theoretically, I could use the highest wattage the device will let me with that coil installed, and it would be mostly safe? Say, 100w on a 0.25 ohm coil? (Because that would allow 100w)

In TC, in mods like yours, there is no preheat, like what we have in DNA200 or DNA75. You must watch the wattage to not burn the cotton. This depends to your coil and profile that you are using. Usually with SS coil, I am not going more than 45 Watts and my preheat is 90 with punch of 5 in 1 second. You should try and error and finally you can adjust the proper wattage. Try dry hit with cotton to see if your cotton burns or not.

Thanks! Will do! This mod actually lets you set the wattage to start in TC mode, I'll have to check it out when I get the device! Haha is it safe battery wise to fire this thing at it's full wattage? Or is that not even recommended? It's a Li-Po pack so that's what I'm iffy about.

Nothing unusual will happen bro. No matter what battery is. Its just ohm law which speaks. And your mod designed to follow it
