Wiring help

[Richard Tweed]

Hey guys I'm new here and I cant seem to find the post I am looking for so I'm sorry if this is in the wrong place but here goes:

I am making a stabwood box mod and I'm having a bit if trouble getting my head around the wiring aspect of it.

The mod will be dual 18650 and the chip will be the YiHi sx485j, I was going to use battery tubes from the mod maker website which sure would be easier because they have the positive and negative solder tabs on the top but I saw a guy on YouTube (oi modz) using a battery door setup, my question is how does the wiring work when using a battery door that is on a hinge?

I'm sorry if I haven't explained this very well lol.

I would really appreciate any help guys.

Door acting as a negative contact and he probably wired that bottom plate or in some cases I saw a contacts are part of doors but that can work in case you have spring loaded contacts to have a good contact

as far as I'm aware the sx485j is a single battery board I have seen no diagrams for a duel wired set up

using the door for a negative is a bit of a no no the Atty and the battery negative use the same wire

can you edit your post and change the font colour of the text, please

As Stu says above the board is designed for a single battery (I.e. 4.2v) in terms of voltage but you can wire in parallel - NOT series.

You could use a hinged door but it can be a little complex when considering your current path - I.e. you don’t want your current flowing through the hinge itself as that’s bad practice, so perhaps you could use a spring loaded contact or even a flex wire onto the door.

You can split the negative off into the atty/ board but my suggestion would be to go down the twin tube route for ease.

When wiring in parallel you want to solder the positive and negatives of each tube to each other and then to the board, NOT the negative of one to the positive of the other etc as that would give you a series connection, which will fry the chip.
