I have made videos showing you how to make a 5 volt Detonator. I want everyone who has decided to make one to know they do use unprotected CR2 batteries. I am determined to make them as safe as possible.

This is a description of my take on how to make your mod safer.

No CR2 batteries are protected
Non preotected batteries can ALSO vent-
Batteries vent they don't exploide.

Venting happens if the batteries discarge too fast- the way that happens is a short circut- infinite loop where all the power is drained quickly.

All parts in my mods are heatshrinked and encased in expoxy-- much much less chance of a short.

Also the regulator does not allow the entire unit to drop below 5.00 volts - doing this means each battery can not drop below 2.5 volts. The regulator will not allow a drop below 5.0 - and not allowing any more voltage through it below the 5.0 volt will also stop a rapid discharge.

OK- but what if venting does happen?

The Mod you saw where the batteries vented did not have vent holes. With out vent holes the venting batteries preasure is either going to blow the end cap off, blow the attomizer off (hope fully not down someones throat) or blow up the body of the unit. Not Mine!

I drill vent holes in all my Mods. If everything gose wrong and the batteries do vent the batterie gasses will go out the vent holes. The vent hole are near the end. The worst that could happen is a litytle hot battery venting would get on your hand. My Mod will not blow up.

Best Tip- make sure to allways use your batteries in Sets of 2 and keep the sets together. Number the sets. Dont use 1 half charged battery and one fully charged - doing this will put too much stain on the 1/2 charged battery.

Hope this helps. You have nothing to worry about. Vape on.

Heatshrinking and Expoxy Shells. I have also poured epoxy inside covering everything making them really solid inside thus preventing any movement or chance of broken connection or short. This IMO will prevent batteries from rapidly discharging and possibly venting.

All now have 3 Vent holes enely spaced like this

Thanmks Man, Doots got one of the first 2 LED versions.

Right it will not vape below 5.00 volts.. Also, if you notice When the batteries are low and allmost ready to go below 5.01 when you push the button the Red LED will come on and the Green LED will dim just slightly. Nice visual recognition that you have 2-3 more puffs then you need to change the batteries.

Hey Doots I glad you drilled your own vent holes- they do add a little character. I like 3 evenly spaced holes. Note- I also drilled a few hole in the inner PVC sleeve. You may want to if you haven't allready.

I tried putting the batteries in WRONG positive to positive- They didn't even get warm.

1. CR2's Don't blow up! They vent if you build a lousy mod without heat shirink and or other protection from short circut.,
2. I make these with a lot of short circut protection so they don't vent.
3. I know the battery gasses will come out the vent hole if this happens. It's a hole gasses will go through it.
4. I don't know how exactly I could make this thing fail.

Tape the switch on, and drop some solder on the top to short it out.


Some batteries are just bad, and some could blow up. I think I read from one supplier it's like 1 in 100k. So it's like winning the lottery if it happens. I bet most do vent when I issue happens inside of them. Yet, how violent is that venting?

Hell I have seen a car battery explode before when charging it.

I have to agree with Damulta on this one. Yo make the statement....

The Mod you saw where the batteries vented did not have vent holes. With out vent holes the venting batteries preasure is either going to blow the end cap off, blow the attomizer off (hope fully not down someones throat) or blow up the body of the unit. Not Mine!

without actually causing one to fail on purpose you can not be for sure it will not blow. If you are going to make the claim you need the proof of what will happen. That is essentially what the fda is banning things for now a days. Making statements that have not been proven.

A way to do it without destroying your connector with solder. Just leave the connector off and run two wires out. Tape the switch shut and twist the wires together. Dead short will see what happens. And like people like to say. Didnt happen without video.

By the way glad to see the vent holes anyway. Every little bit helps.

I could do that- I'm sure it would ruin my batteries. If nothing happened except the batteries failing then someone would say why don't you do it to 10 of them and see what happens to 10 or 100 or whatever. If the FDA want to buy 10 Detonators to test they can.

Did you see this? http://www.e-cigarette-forum.com/forum/e-cig-technical-issues/45944-boom-battery-failure.html

His Mod blew the end cap off because there were no vent holes to allow the gasses to escape.

I have drilled vent holes in all my Mods to prevent this from happpening.[/COLOR]

I am not claiming to have made CR2 batteries completely safe.. All I am saying is if you use CR2 batteries in your Mod, I would make sure it has some vent holes in it.

While I agree with almost everything you have said, the statement that batteries don't explode is false. I have had a faulty cell fail spectacularly while charging. The vent holes did not do their job fast enough and poof! Explosion! Of course, no video as I wasn't expecting the cell to explode! Would I expect it to happen again? No. Is it possible? Yes.

Batteries do explode. Some are faulty, some are used as mismatches, and some are due to shorts. Saying that holes in the mod will keep them from exploding is ridiculous! Less likely yes, but you cannot make a guarantee like that.
The likelihood of this happening is very slim, but we have seen that it does happen.
Never is a pretty big word!

BTW. Posting that it wont happen to one of yours puts you in a pretty bad situation if it does ever happen.......
Reads like thats a guarantee from you!

In this sue happy world that is EXACTLY what it is. There will be someone who buys it and makes it explode on purpose in their hand and will then sue! Thats the risk modders take when they sell their creations. Don't give a never happen guarantee unless you are 100% sure it can NEVER happen.

Prodigys, Jantys and others are protected because if their is an explosion they can test and prove the batteries were the cause, and not be held responsible. By making the statement that you mod will never explode you just took all responsibility for what MIGHT happen.

Hummmm I kinda need 20,000 for a harley. How much for a detonator??

OK lets say CR2 batteries can explode. I never said having a few vent holes in the body would keep them from exploding. Your right that is ridicilous where the **** did I say that?

If the worst was going to happen to batteries in a Mod that was in my hand I simply would rather have it happen to a Mod that has vent hole as oposed to a mod that didn't have vent holes.

The more preasure that is contained, could potentially do more harm. By drilling holes you allow that preasure to escape. Get it? Holes allow the preaasure to escape.

Super T1, SB, both have these holes. Now the Detonator has these holes- If you make one I suggest you drill some vent holes yourself.

You said it right here^^ ( first post of thiis thread)


You know what, I just spent 15 minutes writing a post here and decided to delete it. Its not worth it.
Im not going to try to explain to you anymore.
If you feel that your mod is fail proof, then feel free to tout it as such. It a free world.


Over and Out!!!!

Ok it should say hopefully not mine. Again I think this makes it safer. If you have some idea of how to make it safer- then go ahead and explain it.

I best idea I could think of is to drill some vent holes so that hopefully mine wont blow up.

The video I saw that showed me how to make one never mentioned them. The first Mod I got didn't have them. The first place I read about them was from Super T Manufacturing.., It allways seemed like a good idea to me, and I finally decided to copy it.

So get it straight I think it's a good idea. I think if something goes wrong it would be nice to relieve the pressure by letting it out holes. I am in no way saying holes will protect you. Shreck is right the hole may be there and it may still vent blow up hurt you or whatever, who knows. The first holes I drilled were in my fiance's because I think it is safer for her to have them. And you too.

Having holes in my mod does not make it fail safe, I never meant to say that. I do think it makes it safer.

Yes I do agree, the holes will help make it safer without a doubt. It will not eliminate the possibility of an explosion, but it indeed will help. I have been working a built from the ground up, CNC machined mod, and it too, will have a vent hole in it.( actually 2)
I just would really hate to see you get yourself in a bind if something ever was to happen , and it just so happened to be something that you made.
