Hey guys. Anywhere do you think I can get a small voltmeter display? Price and dimension? Cause the ones at RS-online is very exp lol. If not then I guess I'll do without it and use guesstimation whenever I tune my poti without DMM. BTW I'm gonna do a box mod during Xmas period.

dont buy those 2s~6s, can check 2 battery above only, 1 batt dont jalan.

Oh not that a multimeter don't work. But imagine I'm outside. And I wanna vape a flavor with a particular atty at a certain volt can't possibly ask me to whip out the meter to check and tune right?

Ah yes that's what I'm looking for. Maybe can mod it into a smaller 7 segment display.
My ultimate aim is to add a digital poti. Haha.
Now I need to consider space requirements.
Thanks a lot.
welcome.
btw, the housing for my display can put 2-10440. just too lazy to mod.
wat model/brand for digital pot?
any diagram to show wiring bo?
Haha. What box you are using? Bought it off shelf at SLT? I'm gonna parallel the batts to have it 7.4 then regulate it using LM2576 adj to 5v and below using a timmer poti hopefully can find a 2k poti so that my minimum is 3.7v. Problem with LM2576 is that most schematics I see uses capacitors. Which I'm curious what is it for and whether I can do without since I'm not building precision voltage/current regulators.
As for digital poti I'm still researching. For the package numbers you can search for it at RS online. They have a bunch of it. I'm gonna create my mods with plugs and connectors. So that when I wanna upgrade to a specific function I can do it easily without desoldering the main regulator board.
I guess my voltmeter can wait till the festive season are over.
By the way. When I'm surfing black-tactical I see that they are selling CGI batteries. Are they good?
Oh ya one more thing. What do you use to hold the 510 connector and the other stuffs together in place? Hot glue? Epoxy?

Just simple epoxy, clear stuff is the most stable

I see thanks!
Oh ya.. just a curious question for modders.. I keep seeing most uses a step down regulator eg. 3.7x2= 7.4v to 5v
why no one uses a step up regulator instead? from 3.7v to 5v?
if no one tried this.. I might.. and see what happens.. after I settled the step down version.. heh..

The step up version would just drain the battery faster....

ohhh and here is a nice mall voltmeter you can incorporate into the box

Ooo. It's really small but do this need an external power supply? I need clarifications on what does S1-S6 means.
The thing looks quite big in the pic... u need a big box sia.... I'm still procrastinating on starting my 5V box mod despite having all the necessary materials. I'm too lazy....
