Mod / Battery Amps Question

[sM1986]

QUESTION W/O HAVING TO READ ALL THAT
Should I get different batteries pulling 20-30amps on a Wismec gen3? Currently using Samsung 30qs and LG hg2s.

I'm Vaping a 25mm VCMT @ 0.25 ohms (ish) on a Wismec Gen3 at 110w. This pulls about 5+ volts and 19-21 amps. I'm running 3 Samsung 30qs. Now I know this mod heats up more than others when chain Vaping. Mine does get rather warm but never cuts out or gives any warnings. Nor am I exceeding the mooches 75 heat point ever. So no issue there.

The question is whether or not I am okay with and should stick with the Samsung 30qs or switch to a different battery. With the mod batteries being in series i know that amp draw is the same from each one. That being 20amps as mentioned before. Mind you my longest hit is maybe 2 seconds. So, am I good? Do I need higher amp batteries? What if i went to an even higjer wattage, say 130 -150? Going to be buying new batteries soon and would prefer to buy the correct stuff.

I apologize in advance if this is a dumb question. I am just wanting to use the proper battery for my setup. Don't want to kill battery life for no reason or get it so hot if another battery could help that.

Thanks guys.

Just like to add, that i can build a higher res coil. Dont think that would necessarily be an issue as I usually build around .3-.5. I just started noticing the high amp draw when I built down to .2.

I'm rather enjoying the flavor of my Simply Serious Sherbert here. Not so sold on the Copious Crunch with this build though.

Edit -
Just wanted to add that my wife vapes a 25 vcst on a gen3 with hg2s (she likes them better) with a .13 coil @4.03v 125w with a 29.1amp draw and doesn't seem the least bit concerned lol.

Am I just over thinking all this? Sorry for making this so drawn out for a simple question!

IMHO, the best batteries and the ones I use for everything are LGHG2's. Excellent capacity, high amp rating, and quality is good.

In pure terms of battery safety, the coil resistance does not matter on a regulated mod. The volts and amp draw that are displayed on the screen of the mod are the output volts and output amps (output by the board─and to the coil) so these two numbers do not reflect how many amps are being drawn from the batteries (input amps).

110 watts divided by 3 batteries, divided by 3 volts cut-off voltage of the mod, divided by 0.9 to account for the minimum efficiency of the mod, means you're only drawing 15.6 amps per battery. Lithium-ion rechargeable batteries start aging faster if the battery temperature rises above 45°C (113°F). Vape on your setup for a while. Next, take out the batteries. Feel how warm they get. If they are just lukewarm, but never actually warm, then you can expect your batteries to last way more than a whole year... maybe even several years. If, however, due to how you vape, they get warmer (but never actually hot of course), then you might slowly start to consider getting Sony VTC5A batteries instead. Finally, if you can't─due to how hot the battery is─hold your battery by wrapping the palm of your hand tightly around it for 30 seconds, it means your battery is much, MUCH too hot so if that's the case... then just grab yourself some higher amp batteries, as you'll get seriously better performance from them in every possible way─and it'll be lots safer.

What he ^ said. Output volts and amps aren’t the same as input volts and amps. Any quality 20 amp batteries are fine for any decent modern variable wattage mod.
