Building my first Unregulated Box... Advise and benefits from series to Parallel??

[EverPresentNoob]

So I bought all the stuff to make an unregulated mosfet box, and now Im trying to decide if I should build a parallel or a series box... Im going to be wiring it with 12G wire, but I was wondering what the benefits of building parallel or series would be. The batteries will be VCT-4s. IM looking for something that I can use for huge clouds. I have wiring diagrams for both, just looking for pro and cons of each. I currently have a few single 18650 mechs, and an ipv4.

hmmm.... No one?

hmmm.... No one?

What is the difference between batteries arranged in series Vs parallel ?
Please share what you know.

Cheers

thats kinda what Im tryig to learn here.. I know parallel mostly doubles the amps, while series doubles the voltage.... Im trying to learn which would be better to build. Or heck, its just wire, I may just make it so I can switch between the two.

Ok, thanks for all the advise and pointers. Ill take it all in and see where i go with this. Got my Hammond box today, the rest of the guts should be here tomorrow. Gonna get my Solder on, and then get my vape on!!

Parallel is the easier of the two plus you get the amperage of both batteries. Sure you get more voltage with series but you only get the amperage of one battery. 12ga is a little overkill. What parts did you order?

Hammond box, Fatdaddy spring 510, antivandal switch, mosfet and a dual 18650 tray. I know 12g is over kill, but I figure why not. perhaps I will have less voltage drop that way. And I have a lot of it around here. I use it for speaker wire in my car and bought a large spool last time I did an install. Granted it means all the wire will be the same color inside, but it will look uniform! Just realized I dont have a micro switch to use as a internal kill switch, and my voltmeter and magnets arent here yet. The box is already here, and the rest of the parts will be here tomorrow when I get home from work.

so with paralell I can build lower, but I will have a little longer ramp up, right? Im ok with that. And if I find later that I want the voltage, I can just build another one!

If you use a micro for on off then just put it in line with the gate on the mosfet. It doesn't carry a lot of current. It wont actually shut it of but it wont fire. You can get ready because I started like that. Just going to build me a box. Then a triple 18650 then a series box then an sx350 then and so on. Its addictive.

well, a little update. The box is dont and working pretty good. I ordered a Hammond B box, so the thing is a littl elarger than I wanted. Didnt really notice it until it wa built and I was vaping on it all day long. But it works well. Now I placed an order on Digikey for all the parts needed to make a Raptor box. And I got a printed PCB to build it on. the whole thig is designed to fit in a HammondG series, and I found a company that CNC machines teh boxes so I wont have the Hammnd Lean going with ths one. Hope to have it done in the next couple weeks depending on when teh PCB is printed and shipped. I could only order the PCB in multiples of 3, so i am going to have a couple extras...

Must be oshpark. Good company. Ive ordered a bunch of boards one of our members has on there. David4500. Good luck and be careful. Which raptor are you doing? http://modcrate.myshopify.com/ check out this place. I get a lot of parts from them.

 

[EverPresentNoob]

Yup. Osh park. I ordered the V3 board by Dickbuttmods. then got on their Facebook page and saw they have a new V4 board... So the idiot in my ordered one of them as well. Going to be using the Raptor 20a board that puts out 120 watts. The box will be from AlpineTech, their 1590g+. I believe it adds a couple millimeters to the dimensions of the G for just a tad more clearance.

Wow. Just reread my last post. Thinking I need to double check that my spellchecker is working...

Ive used a bunch of there boxes. There good quality. The raptor is a fun project. Pretty powerful to. Hope you solder skills are up to it, Haha. Its not that bad

 

[EverPresentNoob]

And the raptor is alive and kicking fantastically. So much so that it has replaced my IPV4 as my daily use mod. It was a trick getting it al fit inside the box, but Im happy with it. So much so that I bought all the stuff to build another one, but am custom making a wooden box to put it in. Ill take pics of the second build as I assemble it and make a new thread with it.

Cool. I really like the raptor. Its a fun project.
