Lower voltage batteries for mechanical mods?

[jersey_emt]

I was wondering why all of the battery types for mechanical mods (18650, 18500, 18350, etc.) are only available with a nominal 3.7 volt output.

As we all know, different juices taste best at different voltages. It would be nice to be able to just change to a lower voltage battery when you vape a juice that works better at a lower power level.

A coil with a resistance of 1.0 ohms at 3.7 volts produces 13.7 watts. Let's say that there is a 2.8 volt battery. Then that same 1.0 ohm coil would produce 7.8 watts -- perfect for those juices that don't take high power well.

But you need another special charger for them too

Thus the beauty of APV's...you can adjust the voltage to the head, no matter the resistance in the coils

For a mechanical mod, to lower the power, you need to up the ohms of the attached device a little

It's a lot simpler to get a higher ohm coil.

How is removing the coil, building a new coil, and checking its resistance simpler than just swapping out a battery?

First you need to do some research on the batteries we use. The IMRs recharge the fastest and hold their power longer. They also handle the amp draw we place on them. Thats how a mech works if you want ADJ and dont want to change your resistance stick with your regulated mods.

Or you can invent a Vapor IMR line of batteries that increases in .1 increments in voltage out puts so we can buy 2.5 up to 6.0 v batteries.

I would get two of them but you have point.

You could always use a kick to set the wattage at whatever you want... Thats a lot easier than messing with wierd battery types, or rebuilding a coil. You would have to rebuild at least one coil though, as most kicks only work at a minimum of 1.3 ohms.

I have done my research and completely understand why our specific application requires a specific type of battery. All I am asking is why are they all 3.7 volts?

It would be nice if there were a suitable battery which could be used that would allow a mechanical mod to operative at a lower voltage so you could use the same RDA to vape different liquids closer to your power preferences. Because in almost all cases, a spare battery is cheaper than a spare RDA.

Basically, it would allow a form of variable wattage (albeit a rather crude form) while still offering the advantages of an unregulated mod.

I take it you dont rebuild very much the few points of wattage make no difference in a properly prepared mech coil, the only think you notice is the amount of vapor dropping off.

I suppose it's some sort of chemistry thing. All lead/acid cells are 2V. All alkaline cells are 1.5V. I don't think the chemistry allows for any dinking around.

But they all go from about 4.2 volts down to 3.3 during a normal, safe cycle. A Kick is much simpler than trying to make a customized regulated battery.

If you want a mechanical you stick a Lithium battery in it. If you want a lithium based battery you get 3.7 volts optimal - it's the nature of the chemistry. If you want voltage lower than that dump the mechanical and get an easy to use VV mod instead.

 

[beckdg]

bingo.

if you insist on a lower voltage battery while still having the power to fire a coil consistently then you veer from lithium chemistries to other battery types. when you do that, it becomes painfully obvious very fast that to sustain the current we need without damaging the batteries at those lower voltages, the batteries get bigger and heavier FAST.

i mean, sure you could do a 2V lead acid DIY mod... or 2.4V nicad or nimh DIY mod. but you'd probably need anything from a fanny pack to a back pack to hold your battery for the average person.

I have to disagree. Every aspect -- coil resistance, coil configuration, voltage, etc. -- changes how a particular juice vapes, and the power level (watts) is one of the most important. Juices can taste very different at different power levels; otherwise VV/VW mods would not exist.

That will just turn an unregulated mechanical mod into a regulated VW mod. I already have two VV/VW mods, so I don't want to convert my mechanical mod into a third one.

That makes perfect sense. The LFP batteries mentioned by WarHawk are a different chemistry and they operate at 3.2 volts. Unfortunately, that's not really a big enough difference from our regular 3.7 volt batteries to be worth it, and I am unsure it these types of batteries are suitable for vaping.

Here is a thread discussing the 2/3A size NiMH batteries.

What it comes down to is energy density. Lithium gives you the longest vape.

if you want to experiment with other types of batteries go ahead. nimh is a safer chemistry and I see no harm in it. Maybe you will even come up with something new. Not likely in my opinion but you never know.

If you go into the battery section here, there is a DIY for a resistant disk to tailor the volts down a bit. http://www.e-cigarette-forum.com/fo...w-make-any-6v-7-2v-mod-into-5v-modularly.html

It's the science of the battery tech it's been 3.7 for 20 years!

Kick it job done!

Given the cost and for reasons unknown developing the tech would be costly, why re invent the wheel?

Mech Mods with a kick aren't Mech Mods at all!
