VVBox and VVpassthru

[BJ43]

the first pen is ground the second pen is first cell the third pin is the second cell. Isaac going have it on its own mini circuit with on off momentary on switch

We are not using batteries, it is a PT with a 12v power source.

when you buy try to info first. For modds the best is
LED 1s-6s Lipo Battery Voltage Indicator Checker Tester | eBay.

Only wire first two pin to + and GND an you have correct reading.

The meter is used to adj the variable voltage.
To ck voltage to atty and drop in voltage when triggered.
To ck the voltage from the source and the drop at the source when triggered.
To do this it needs to be on its own mini circuit and switch.

BJ43, thanks I appreciate the clarifications, things were getting confusing.
I understand what you are saying now.

I think the other guys while being very helpful (thank you) are focused on a 5 pin lipo and batteries and it's mixing up the wiring.

sorry I thought you were building a multiple power source passed through battery multi atomizer kind of a all in 1 box

I was but got a little too complicated

No problem. this one that gormly is building is just a VV passthru with meter, a 12V source, and two atty..

Ok frustrated now. The box is working just fine, I get vapes on both attys with the rocker switch but as soon as I go below 6.2 volts the display goes away and will not reappear until I go over that mark.

I could only get it to display something if I connected both the red and green to the same output, if I do red or green only I get nothing.. I am not sure what is going on ... ???

 

[gormly]

here is what I have so far, I can't go below 6.2 or the display shuts off but it works LOL

The 2.5 DC connector is a light up version (the blue light inside) and the meter is inside the box, it's aeasier to see in person than on the photo and not obnoxious at all. Very nice, the rocker lets me switch from a Go-go to a 510 threaded carto tank.

The sides have rubber on them and it will fit a mans hand sideways (but probably not a woman's)
It can be switched to each carto and fired with one hand. On off switch to be added later.

LOvely

Did I just make the first dual carto switchable mod??
patent pending? (just kidding)

Battery version next, but wanted to see if I could do this first.

thanks for the help...

If anyone knows why my meter might be acting this way, feel free to tell me

Not sure of the meter problem Gormly. I've seen those on eBay, but haven't seen anyone on here use one. You might check the specifications on the one you have. It might be for a multiple cell battery pack, in which case 6.2V may be the lowest it will read. The meters that have been used here are the 1s-6s meters - for 1 to 6 cells.

that's probably it. I didn't want to wait 14 days to get a china delivery

Mad Vapes sells the same 1s-6s volt meter; theirs is ~$7

Just checked, they are in stock and $6.99

G man... the lipo meters "usually" read to 3v@x(?)Amps.... so will it read below 6.2v if there is only one atty connected? maybe a current issue?..... also maybe just pay 2$ with free shipping for the 1-6cell lipo tester from madvapoes, but buy from ebay, cheaper, but longer wait!

BTW....Pretty box!

Found it....this one does 2-6cells, so 6.2v is low as it goes...

This one does 1-6 cells reads down to 2.8....mine read down to 2.6v

This bugger is 2-6 cell but hugh LCD....

That'll make a nice one! I was thinking of one unfinished so I could finish it myself and cover up my mistakes:

If you connected two sources from the regulator to the meter it will cause an error. Also I have found that if I use the pins higher than the third pin without using the 1st pin I get an error. The best way I have found is to use the neg and the 1st pin next to the neg for my positive, I have six working that way and no problem

 

[BJ43]

This is the best setup I have found to read two voltages with this meter.

I bought one and still haven't used it. It has variable watts and variable voltage, good for battery charging and leds but since it doesn't adjust automatically like the Darwin I haven't used it. In other word when I tested it it didn't compensate for a change in ohms, you had to do it manually.

what would that be used for? Battery charging? You are saying I could use this as a way to charge on board batteries?
I'd like to eventually make an all in one with two larger batteries 18650 maybe and a way to charge them via the same 2.5 DC plug, would it be a matter of using a switch to change where the voltage is going? one to the LM-meter-atties and switched to a different LM to the batteries?

Or maybe use this instead of the LM I have and use a switch to divert to the batteries?

I would want something with the balancing feature in the internal charger.
I am looking at something like this, it is the smallest I have found so far, Dimension: 67mm x 47mm x 21mm
