Dual Coil and 14500's

[b4cz28]

I bought my first mod and have only been running dual coils. I have a 3.7 v box mod running 14500's. I only get a few hours of run time before needing to swap out the bats. Is this about right?

Depending on the resistance of the cartos, you are pushing 2.5 to 3.5 amps whenever you are pressing the button. So you should be getting about 10 to 20 minutes of button pushing time.. My math was very rough. But vaping for a couple of hours sounds about right, depending how heavily you vape.

eta: there are alot more variables... batt quality for instance.

I've found that Dual Coils are very hard on14500's and eGo batts. I've killed 2 eGos and one protected 14500 in the past couple weeks. Actually, an unprotected 14500 just died after only 45 minutes of use, so that one might be kicked too.

ANy batts that work better with the duals? We are just having to change them all the time. I might jump to a 5v box mod that can be adjusted to 3.7v (madvapes) to get a better run time.

I believe that those 5V boxmods from Madvapes just use 2 14500's in series. So you won't really get more time out of them and you'll charge 2 every time. 2 batteries in parallel would give you more runtime. Moving to a bigger battery like an 18650 would give you much more runtime. Mine go for about a day. Your results may be different.

two 18650s in parallel gives a pretty good run time

Well at 5 volts with a 1.6ohm carto which is where them DCs run your vaping at 15.6 watts. I ran tests on LR cartos at around 5 volts both 1.6 ohm and 1.8 ohm cartos and burnt up 3 sets of batteries. I would recommend if your going to use LR do it on 3.7 volt ecigs they were designed to be used on but it's still going to lower your vape time between charges. I personally won't use LRs but I don't need to with Variable voltage.

Rocketman has your answer you need.

OK, HELP A NEWB!! I have 3 ego batts and two riva. Just got into doing DC, why might this fry a battery/

 

[demon72]

they havent fried mine (yet)

 

[LauraBolyard]

GOOD!!!! no responses??

damn i wish I knew more about volts!! EVENTUALLY!!!

Not just more runtime, they will also provide higher vaping/loaded volts. Under a heavy load with a single 14500 you also get a heavy voltage drop/sag when you vape.
