So it worked for a while, and now it's getting hot again?

What else did you change besides the battery? Think back...

Did you change/fix/re-wick/recoil the head when you changed the battery?

Are you using the same watts now as you were Monday when it worked?

Sorry to hear it, but the battery was the cheapest place to start. If you avoid using it and it never got really hot you can probably use it in your next mod. Good luck!

    Sorry, couldn't resist the chance to chuck in a silly question. With VV, if you're using a stainless steel coil, will the vape tail off just a little as the resistance changes (presuambly increases)? Would that be more pronounced on something like ss430, with its slightly higher TCR? And if VW adjusts the voltage to maintain a set wattage, it wouldn't have as much to do if you're using (say) kanthal? So VW sort of implies resistance tracking, whereas VV doesn't?

    Thanks.
    The TCR isn't high enough except maybe with Nickel wire or maybe Titanium. Both are hard to work with, nickel comes up with too low a resistance even at low power for most VV mods (i.e. you're down at 1-2 volts), and both can poison you if this doesn't actually control the temperature adequately.

    I do think that TC was in a sense obvious once VW was around, because if you VW a temp-sensitive wire it fights against the (small amount of) temperature regulation that would otherwise happen!

    The Saber may be rated 100 watts but very few cells are capable of that. I don't know if we ever heard the actual power setting but that tank can use most or all of it. In other words, even at best you're running right on the edge. You need lower power tank or coils or go to a 2 cell mod I think.

    60 watts – which would have a current draw on the batteries between 15 (at full 4.2 volts) and 20amps (at the 3.2 volt cut off). A 20amp battery would be sufficient.

    Thing is, both Ni and Ti should only be run in temp control mode. Running in VW/VV is a no no.

    ^^-- I thought I said that, while explaining the how My Batt Hurts' idea is partially implements it but not enough.

    There's actually 2 ways to do VW, one is measure the resistance before or at the beginning of the hit, calculate the voltage to apply, and hold it through the whole hit. The other is to constantly measure resistance and if it changes, vary the voltage immediately even if mid-hit. If that is how the power limit is applied in TC, this results in the voltage increasing as the coil resistance increases, until the protect threshold is reached and then the voltage drops sharply. Or, TC can also be done using the first method, that would be my choice and probably how most do it. Of course, the difference is insignificant with SS, and Ni and Ti are moot as far as I'm concerned. But it is still interesting.
