need help with custom series mod
i recently commissioned the build of a custom purpose built series box mod its an unregulated box of course but im having issues with the coils what would you recommend im currently running 24g wrapped on a quarter inch rod wrapped 12 times and its still way to hot even tho i drilled three massive air holes in my tohb atty any help would be a god sent lol

RE: need help with custom series mod
Welcome to the forum! 
I'd suggest getting a Doge or Mutation X RDA. Those are both great atties with a ton of airflow and a cool vape. 
If you don't want to get a new atty (although I don't know why anyone wouldn't want an excuse to buy a new atty lol) I'd get some 28ga kanthal and learn to wrap dual parallel coils. The smaller wire won't carry as much current, and with parallels you can make more wraps while keeping the resistance low. About 8-10 wraps on your 1/4" rod should give you a .4-.5 ohm build that tastes great and isn't too hot. 
Actually, I recommend building dual parallels even if you do get a new atty, just because they're awesome.

RE: need help with custom series mod
i have a doge and a mutation x v2 and they are pretty awesome. so far tonight i have experimented a bit and a 15 wrap dual coil with 24g is the coolest ive found, it comes out at 2.5 ohm and is still a train. Once the shops are open tomorrow ill give the parallel a shot, that was one of my first thoughts but the shops all closed early due to it being sunday.

Yeah parallels are great since they can stay cooler while having a lower resistance, and they have great flavor. I pretty much only use dual parallels these days. I like a cool vape myself, and I like both flavor and clouds, so I'm always trying to find better coils.

Hi and welcome kacdiers!

You need to increase the resistance probably. Simplest way would be to get some 26 or 28g wire and use that instead. Doubling the voltage (I'm assuming it is 8.4V) has the same effect as halving the resistance.

So more air and more resistance should help.

I'll come back to this when I get home, DONT DO PARALLEL COILS. You want to be using .4 kanthal on a è or 4mm bit to wrap your coils.

Gords why so adamantly against parallels?

RE: need help with custom series mod
Because you want quite a lot of thick kanthal due to the power output. Parallel coils is absolutely the last thing you would do. You dont want low resistance you want higher sub ohm builds with lots of surface area. I'm using .45 or .5 kanthal around a 4mm bit to end up close to an ohm on the giggle box.

If it's a series 18650 box then the absolute lowest resistance is about .4ohm, you're still limited to between 20 and 30 amp maximum draw by the cells.

Because you want to stay above .3 ohm and you want to be using .4 or .5 mm kanthal to do it, building for higher voltage is nothing like building for a 4.2v mech. You want to coil around a 3mm or 4mm bit, you definitely dont want to be so low you're into the pulse current of the cells. Its more than likely hot because its not wicking well enough for the wattage. The absolute last thing you want to do is drop the resistance any.

RE: need help with custom series mod
I had never thought of that, but it makes sense. I use parallels on mine and they work great, but I forgot I'm using a regulated mod at around 70w, unlike his unregulated box mod. Thanks for the info gords.
