I am about to jump into the world of creating custom mods and hopefully getting to the point of selling some here at ECF. In the meantime, I'm doing some mockup drafts of a device I'd like to make, and I have a question regarding battery placement. This is going to be a box mod (I think a box would be a great starting point) and this is how I envision setting up the batteries in the mod:
Now, what I'm thinking is using two RCR123A batteries in my first test. But, that draws up another question or so.
With this box mod, I'm looking to add a potentiometer so that the box mod can go from 3.7v all the way up to the battery max that's put in. So, my first question is, would RCR123A batteries be able to be placed side by side like this? I know people talk about "stacking" batteries being bad, but would this be considered stacking if they are placed side by side in fashion where they are locked into place? (Think the AA battery pack that comes in those Radio Shack DIY kits).
Now, something else that came to mind is the ability to go over 6v for anyone that would want to go over. Would a potentiometer allow the user to go over 6v? I've only seen potentiometers that topped out at like 5.X volts, but I could have been mistaken. And if a potentiometer CAN go above 6v, would it be possible to make the added space so that the two battery slots can fit two Tenergy Li-ion 2600mah 3.7v 18650 batteries? I've got a TON of 123A batteries and I have two 18650s that I would be able to test in my mod, but I'm curious as to how it would all come together.
So, there we go. To sum it up:
- Would two RCR123A batteries be "stackable" if they are placed side-by-side like shown above?
- If I want to create a box mod that goes from 3.7 volts all the way up to 7.0+ volts, would a potentiometer allow me to go that high? Or do potentiometers "top out" at certain voltages?
- Would I be able to use two 18650 batteries to achieve the higher voltage range, and would those two 18650s be able to be limited all the way down to 3.7 volts by using the potentiometer?
- EDIT: Another question: if I were to put an LCD display in this so that potential users are able to see what voltage they are at (I would assume that's a MUST in a VV device), do those LCD displays also stop counting after a certain "max" is reached? Or would it display 7.0+ volts just fine?
- EDIT: What about using just ONE rechargeable 9v battery? Would a potentiometer and LCD be able to adjust and display those voltages correctly? That would also help cut down the size of the box mod a LOT!
I think that's basically all of the questions that I have for the time being. I'm going to go and speak with a machine shop tomorrow morning to get some quotes on how much it would cost to machine this mod out of metal parts so that it's insanely durable. But, all of that will come with time. For right now, I need to get the "basics" figured out and get all the part placements down first.
ANOTHER EDIT: I was looking at Mad Vapes for a potentiometer, and for some reason, I couldn't find one on their website anywhere. I found the LCD screen to display the voltage, but no potentiometer. So, I did a little Google search, and found these:
Not sure why the URL isn't showing above, but the spot between www. and .com is:
a l i e x p r e s s
Why does that URL not show up right? Are they banned from discussion here or something?
Are those the right kinds of potentiometers to choose to put into these suckers? If not, what should I be looking for specifically? Thanks a lot!
