What battery are you using for 4.8 volts. does that work well with dual coils (1.6)
These are the 4.8v ni-mh batts and charger. I can't speak for kgeiger002, but I use the ni-mh batts with dual coils every single day. It's my favorite set up.
Using the LiFeP04 3.2 volts. Which are closer to 7 volts of the charger. Just looking for comparison of 5 volts to 6 volts. I also have a 3.7 (4.1 off charger) and after vaping at 6 volts 4.1 volts too low
I have a couple of madvapes voltage indicators. They let you see the load voltage while the atty or carto is being fired.
Here's what I learned: The lifep04 batts can only discharge around 3.1 or 3.2 amps which produces 5 to 5.2 load volts with a 1.6 ohm dual coil. So, even though you're charged to 7.0v, you are producing around 5.0 when the circuit is complete. My BDL IMR 18350s stacked can produce around 6.2 load volts even though they are charged to 8.4. My AW IMR 18350s get pretty close to 7.6 load volts. - Most of my li-on 18650s at 4.2v off the charger produce around 3.4 load volts. --- The 4.8v ni-mh batts produce right around 4.4 load volts fresh off the charger and die somewhere around 3.6 load volts, so they are a step above a li-on 18650 even when they are about to die.
I hope that helps.

Great....great info. The only reason I had thought about the 4.8 volt battery is the 3.2 volt battery @ first hit just a tad (but useable) high the vape is real warm. So I think I will just get another set of the 3.2 volt batteries so I have enough for a whole day of vaping. Then I dont need to mess around with another charger expense
I got my roughstack Maxi V2 today and I tried to use the 4.8 volt Nimh batteries on it (the 4 X 1.2 volt ones that are encased in green plastic) as my preferred set up and they cause the atty to continuously fire without me pressing the button. This is disappointing because I wanted the roughstack mainly as a 5 volt mod and I bought the Nimh batts and charger specifically for this purpose.
Any ideas on how I can correct this? I notice the top of the batts are flat which is different from the 18650 batt.

Thanks for the advice.
Damn. Not keen on ordering something worth $1.50 which I have to ship from the US to Australia with another 10 day wait!! I might try and find it in Australia. Im surprised Madvapes don't throw these in when someone orders the Nimh batts.

Madvapes doesn't carry them. Go to the arts and crafts department of whatever Australia's version of Walmart is and look for rare earth magnets for crafts projects. You'll probably be able to find a 4 pack of the 6mm magnets there.
I will give that a go! There is a hobby store around the corner. The guy will either know what I am talking about or think I am trying to invent a backyard nuclear bomb. I am not an electronics kind of guy and am afraid my Roughstack might explode in my face when I start sticking peices of metal in it.

A blob of solder in center of switch assembly works.
The soldering of a blob on the assembly worked! The hobby shop owner knew just what to do and I now have two fully functioning 4.8 volt Nimh batteries for my Roughstack. Thanks so much guys!
Is it normal to be this happy that I rectified my 5 volt aspirations for my Roughstack? My friends just wouldn't understand.

Just got my RS (18350 body) and there is no straw. And, not surprisingly, it doesn't work. Has anyone else gotten an RS with no straw?
The new RS's have no spring nor straw. I have a maxi with a wire connector, and it works fine.

What kind of issues are you having with yours?

It just won't fire. I've tried combos of 6 brand new 18350 batteries from MadVapes, multiple brand new 510 cartos, 510 atties, 306 atties, and nothing. Disassembled the switch and nothing look amiss. Bottom spring seems ok and battery is making contact.
At least it looks nice.
Update: Looks like I have the new switch without the spring and straw.

I encountered something strange when trying to troubleshoot.
The bottom spring is cockeyed and bent in an odd shape. If I don't screw the top cap all the way on it will fire on all of the "MadVapes 510 Dual Coil Stainless" cartomizers (MadVapes #3152) that I've tried as well as an LR 306 (MadVapes #2890), SR 306 (MadVapes #2891), and a few 510 atomizers (not from MV). The vapor production is very good at 3.7v with a brand new 18350 (MadVapes #3116).
When I try a "Dual Coil Stainless Mega Cartomizer" (MadVapes #3125) I will sometimes get very weak vapor.
So, I'm not sure if it's the switch or perhaps the bottom spring, or a combination of both.
I'm definitely getting a good connection at times so I don't think it's the center pin.
Volt meter shows 4.09v on a fresh battery with the cap not screwed on all the way.
