Pretty sure most of you guys know about vaping. I'm really into it, and aspire to build my own. I checked other forums and seems they throw around alot of big words I'm not to familiar with. So I just wanna know my basics and build from there. So here it goes.
The chip im looking for a input that will take 2 18650 batteries that will be set in a series, and I can adjust the output setting through 2v all the way up to 10v with a 20amp limit. also I would like to put a potentiometer to regulate the voltage. How do I go about doing that?
You may need to revisit your spec. first. Your 2 batteries will give you 7.4 volts and 2.2 amp hours. You can use a buck boost regulator to get the desired voltages(check E-bay) but if you try to run it at 10 volts and 20 amps your batteries may melt or at best last only about 3 or 4 minutes.
well the trigger would be only pressed for maybe 3 or 4 seconds at the most. Planning to use high amp draw batteries rated at 30 amps maximum draw rate.
How would I tie a buck boost regulator to everything. I don't really know how to put anything together let alone build a board, just yet. so yeah gotta hold my hand for now.
also I hear that a switching regulator would be ideal since the heat dispersion would be kept minimal. wouldn't want the piece to heat up, since it would be mostly held in my hands.
I have seen e-cigarettes but I have not heard the term "vaping". A few people have posted an e-cigarette that is simply one battery cell, a timer and a heater that uses only a few amps.
A 18650 battery cell is 3.2V to 4.2V so two in series make 6.4V to 8.4V when there is no load. A load reduces their voltage. You need a complicated boost circuit to increase their voltage.
A potentiometer is not a voltage regulator. It adjusts the output voltage of a voltage regulator.
The battery is not designed to produce 20A. Probably you will not get more than about 5A from the battery when it is new and less current when it gets old.
but these batteries can
I have a piece that allows 2.7v -5.xx volts. rated at 16amps limit.
So that kinda got me thinking if I can maybe improve on that. I understand what the potentiometer does, just figuring it how to tie it all together.
That is a regulator. The max output voltage is only 5.5 volts.
Do you really want more voltage then the batteries can give?
There must be thousands of regulators on the market, but this one will not work for 10 volts at 20 amps.
Aren't you just boiling some water? Why do you need so much current? A 20 amp regulator is big. a 5 amp one not so much.
Anyway, here is one that comes close.

yes that is true I am boiling water in a sense. But how rapidly is what im really looking for. The chip you suggested is something a little to big. I'm looking for something more smaller, not to much Vin and Vout.
Yes, that one is smaller, but it will not raise the voltage above the battery voltage as you requested, only lower it.
I don't know what you are using to generate the heat - nicrome wire? If so just choose the wire size and number of turns to get the desired results. No converter required.
