Anybody using a box mod that requires 2 18650 batteries?

and or any of the temp control mods that you can use the nickel plated coils on? If so what's with multiple batteries, other than power, and is it rad?

2 batteries means you potentially have twice the power available, or twice the vape time compared to one battery.

I have 4 dual battery mods (not counting istick 50Ws). I love the extra battery life. I also have 3 tc mods, one of which is dual battery.

The wire for temperature protection is solid nickle. There are no plated wires in vaping. I have two dual battery mods and one of them has TP. As has been said, two batteries can be used to double the power, double the time between charging or a combination of the two. I don't really consider this rad, but you might feel different about it

I have one dual battery mod, and I'm a big fan of the extended battery life and moar power. If they're wired in series, it'll double the volts (moar power). If they're wired in parallel, it'll double the amps/amp hours (more battery life), and more headroom for low ohm builds.

I have a Snow Wolf 200W TC mod that uses dual 18650s. I think they're series because you put them in backwards to each other, but I don't know that. And yes, it rocks the house. I started it in VW mode and topped it with a Lemo2 wearing a mere .5 Ohm coil and rayon wicked. It hit like a cannon, so hard I never even turned it up over 100 watts. I only hit it at 100 two or three times before finding a much more pleasurable vape down in the 35W range. Then I recoiled the same tank with a 28ga Ni200 (I think it was a 8/7) spaced wrap on a 3mm mandrel and wicked that down with rayon. I ran the watts up to 50, to cut the ramp-up time, and then changed to TC mode, eventually settling on 425 degrees, and using the same juice. It rocks, dude. It rocks the house. Better than medium cloud and plenty of flavor. So much, I remixed my old standby DIY peppermint down to 30/70 PG/VG and 3mg nic from 50/50 and 6mg. Burn down the house...

With mech mods, using two batteries in series doubles the voltage output and the combined mAh and current capability stay the same compared to using one battery. Since the voltage is doubled, to get the same watts from your atty you need to double the resistance of the build. If you double the resistance the two batts give you twice the mAh (runtime) at the same power. If you leave the resistance the same you get twice the power for the same amount of runtime as with one battery. So you can chose double the power or double the time on a charge.

If you're using a mech mod with dual batts in parallel you get the same voltage output as with one battery but twice the mAh and current capability. To get the same watts from your atty you leave the resistance the same and you end up with double the runtime on a charge. But you have doubled the current capability so you could also double the power by building at 1/2 the resistance which would give you the same runtime on a charge as a single battery at twice the power. So again, you can chose double the power or double the time per charge.

It's the same with regulated mods, you can chose double the power or double the time on a charge when using dual batteries in either series or parallel configurations.

OK, I think I'm nerded out for the night . Going to go dry burn and rewick my atty

Wouldn't you get a great boost in battery life just from the not stressing your battery life when running in parallel? Just curious here.

That is a very good point yuseffuhler and something I never thought of. However this factor depends on battery current drain which I believe will be the same for both parallel and series setups in both regulated and mechanical mods that are run at the same power. I'm going to make sure I got that right at Steam Engine sometime, but not tonight. It's been a long day

If you look at the voltage drop of say... a 0.3 ohm load on a 20A battery, and then divided that between 2 batteries, that's a pretty big difference of stress on the cells (7 a instead of 14a.) At the very least, your batteries would have more cycles in their lifetime.

You got it exactly right my friend and this can make a significant difference in run time before the batteries hit the voltage where the mod shuts down. That was what I never considered before. And the batteries will last more charge cycles to boot.

What I want to double check is weather it really doesn't matter for this if the batts are in series or parallel

+1 love mine too

All other things being equal, yes.

OK, I'm not brain dead anymore tonight . As far as I can tell it makes no difference if batteries are in series or parallel to gain this advantage in run time. That means dual battery mods of any persuasion should give noticeably more than twice the run time compared to single battery mods, as long as they are run at the same power level.
