Ooh nice!Did you get it from NorCalVapes? I want one of those so bad!
That is awesome, I am new to the whole thing but was wondering if the batteries could be ran in series or parallel? I wouldn't so much need high voltage as I would longevity but really interested in doing something like this.
I recognize Madvape's VV circuit. The batteries are in series. The circuit has protection built-in. it is a linear egulator, so it's not as efficient as a PWM. The 18650s should get you through a full day though. I like the Newman's tins. I have one I haven't modded yet. Gotta get to that soon!
I use the popular e-cig circuits in building homemade mods. Madvape's VV circuit was the first I used. Linear regulators are less effiecient than pulse width modulated circuits. They dissipate power through heat, whereas PWM controllers send microbursts of energy and remain cooler, thus more efficiently. Having a step-son who designs circuits for Texas Instruments isn't a disadvantage, either.
If you're handy with a soldering iron, Madvape's VV circuit is a good starting point to building your own mods. It's very simple and has instructions.
I was told not to stack batteries.
From what I understand:
The only reason to not stack is if they don't discharge at the same rate. Then you will be charging one battery with the other and overcharging and under voltage can occur. Same thing can happen when running 2 batteries in any way. So when using 2 batteries just be sure to use the same two batteries you buy at the same time. Flashlights and many mods use the 'stacked' config just fine. Again, just be safe with the batteries. Don't use some random battery you know nothing about (you had laying around) with a brand new battery.
Of course...I could be talking out my ......this is just from what I understand.
