So I want to make my own mech mod in the most ridiculous way possible. Using a 6D Mag light, And keeping it using D cells. In theory a Dcell puts out 1.5v. Six in line would make it 9v capable, Declining as use goes on but still a very powerful mod/home defense weapon. It would be easy to make, it already has a switch, with some adjustments and a 510 to Mag light adapter, mech mod accomplished. In theory. Has anyone attempted anything like this? Would it work? Up sides? Down sides? Opinions?

There shouldn't be any drop in voltage, there are no additional ohms, again in theory. As far as accuracy of the reading, take a meter, whatever you have between pos and neg is what you have. As for it it's bad to stack batteries, it's OK to do it in a flashlights so, it should be OK. I don't know, that's why I'm asking questions.

The first mods were indeed made from flashlights, so it would work. BUT!

Depends what you use as an atomiser/tank on top, since the Li-ion batteries used in flashlights are not the same high drain ones used in mechanical mods now. They are not made to handle the current draw of say a low ohm coil.

Since you have made no mention of electronics i assume you will have nothing but wires, and so one user error and it all goes horribly wrong.

Stacking batteries is usually done with electronic chips to take control of the safety aspects for you e.g. they will not fire a coil below a certain Ω and will cut off if your battery becomes low etc. They are also stacked and recharged typically as matched pairs for life. For safety.

You will in fact be replicating the first mod! My advice: nah!

One alkaline D battery has 12000 mAh. A C has 8000 mAh. While alkalines have lower energy/density ratios, the bigger they are the better they are for current delivery. An HR atty is in the 4-5Ω range, so you could well make this work. If you use two dummy batteries, you would have 6v unloaded, and loaded voltage between 5-6 volts and you could use standard resistance coils. If you look up the Puck mod, you will see how people do with NiMh AA batteries, and your D's would do better.

Wouldn't the dummy batteries increase resistance? That would mean that my voltage would go down, but that could be an advantage, if I make my own dummy battery I can make it whatever ohm I want using only one dummy I could effectively lower the voltage, down like you suggested without sacrificing battery life. Any idea if they sell a 510 connection with wires already attached? I have never built a mod, and that is the only piece I would need to purchase, I have everything else. Mad vapes has a sealed one but if I can avoid soldering on a connection I am unfamiliar with that would be preferable.

Your dummy battery can be as nice or as crude as you want. A solid core of copper or brass (rod or a nail or screw) won't increase the resistance hardly at all. A thin little wire will. I take it your heart is set on using the whole 6 cell flashlight so a single 26650 is rather out of the question. As for the 510, you really want the ground to be physically connect to the body of the flashlight itself and have the positive post come in direct contact with the positive of the flashlight too- no wires. This needs a little fabbing and pressing on your part, but isn't that hard.

You could just as easily make a mod using a dollar store flashlight and 3 or 4 AAA rechargeable batteries. I've done it and they vape at 3.5 to 5 volts depending on how many batts you use. And will last a day on a full charge.

But then it ceases to dual function as a bludgeon. Where is the fun in that?

Hi. Check your thread, here:

http://www.e-cigarette-forum.com/forum/ask-vets-answers/532508-amp-limit-kanthal-30g.html

As mentioned there, I'd recommend going with rechargeable NiMH cells for a project like this. They are 1.2v nominal, so 5 cells would be about 6v, if that's your target. Only one dummy cell required to fill it. Not sure where to find a charger for the D size, but they must be out there.

I've used 4x AA NiMH, in a Puck style mod, and they perform well.

I actually decided to use a 4 D for now, if only because the bulb burned out in the one I use for work, so I am taking that as a sign that I should use that until I get up and running. I do want to use rechargeable batteries in this, because they have a higher Mah rating, and..ya know...saftey...n'stuff... Oh and I can't access the vet forum post for some reason, maybe it's just my new phone.

I just wanna add if your bulb is of xeon gas type do not turn it on then lick your fingers and touch it. It may explode on you sending tiny shards of glass everywhere

It's an incandescent so, no worries on that, but good to know. I'm gonna go out on a limb here and say you might have some personal experience with that.

Ah, probably have to wait until a moderator closes the question, and moves it to the answered subforum. I copied the pertinent part for this thread:

I suspect that you are looking at 1.5v alkaline D cells, four in series. I can't recommend that, if so, as my research indicates that they are designed for a max of 1 amp draw, usually. They are generally designed for long life in low-current applications. As I recall, Maglite bulbs are only around 6 watts. Check this thread, for some more info:

Maximum current draw for D alkaline's

If you want that form factor, you would be better off looking into NiMH cells. They are not common in D size, and some of those are just AA in larger shells. However, they can be found:

Tenergy Premium NiMH D 10000mAh Rechargeable Battery

NiMH is much more suitable for high-drain applications. From the link above, you can see that, though I would not fully trust that max rating. Those top off at 1.25v, unloaded, though they run more like 1.2, so 4 of them would be about 4.8v, while 5 would be about 6v.

I would stay in the higher ohm range with alkalines. With the NiMH, take care not to over-discharge them, just as you should with lithium-ions.
