Need help, 5v regulator, and batteries

[bigv69er]

Hello can you people help me out?

I am going to do a box mod, and will or der this box Transparent Blue 3xAA Battery Box with On/Off Switch

I would like to know what 5v regulator to get, i am only going to run two AA batteries, the third slot i am going to put in a juice bottle..

what type of batteries should i use as well.. I was planning on using my energizer rechargable ones they say they are 2500mAh, but someone told me that wasnt safe..

HELP PLEase PS i would prefer to order everything from the same site, to save on shipping

I have used this regulator with good results. LDO 5 volt, 3.0 amp regulator with control pin! I am sure others will chime in with alot of good ideas aswell. This has the control pin too so you can use any switch you want.

With the box you are going to use. It will make a neat lookin mod but BE CAREFUL while drilling them out, they will crack easily. Especially if you drop it!

The energizer batteries will be underpowered. They each only give 1.5v.. 2x AA's wouldn't even justify having the regulator. I would go with 2x 14500 (be sure they are protected) which can be purchased at MV for a low cost awell. 14500's are basically the same size as AA's, each put off 4.2v fully charged and 3.6 as more of a constant. The AA's WILL work if you use more of them, I would say 4 to give you 6v then your regulator would bring it down to 5v. That makes for a BIG mod tho.

damn i would need 4.. i wanted something small.. the box is already big for me. but i also want to be able to inject juice directly to the carto... so thats why i chose that box..


Ultrafire or trustfire?? ugh so difficult

with two of those batteries do you suggest getting the regulator??

 

[Lazrah]

with 2x 14500's running in series that will give you 7.4v-8.4 w/full charge. So yes, I would deffinitely get the regulator. I have 4x UltraFire 14500's atm and they work fine for me. 2 last me 10+ hours at 5v. I have not tried the others so I can't say anything about them. Other people would recommend the IMR14500's but again I have no experience with them, and MV doesn't carry them.

The 3x AA box will be big enough, but a tight fit. Just Dry fit everything in the box before you start to make sure you have room.

ok thank you!.. i am probably going to get the trustfire.. and the regulator you said..

what do you think about this one? LDO 5 volt, 3.0 amp regulator, D2Pak3
to me it seems more simple because it only has to points i need to solder haha.. and it doesnt seem so complicated..

 

[Lazrah]

You are very welcome, just glad I can help!

I have read a few things about people using those. Haven't seen anything bad about them, so I would say give it a shot. Not sure if you would know this, be sure to use a switch that can handle the amps. I usually go for the 3 amp switches, they are pretty big. Be sure you think about your switch size in that box. The reg, switch, 3ml. bottle, and atty connector might take up too much real estate in the one AA slot. Which leads me back to the reg I mentioned, it allows you to use the sub micro switches.

yeah .. i was going to get this one 6mm x 6mm Tactile Switch with 4mm actuator

its small.. what regulator would work best with that one? i just want something simple lol

Pin1: voltage in
Pin2: voltage out
Pin3: ground
Pin4: disrupt,control,switch

you can always trim the legs on the regulator too, just be careful how much you bend them. They will shear off.

I know you want a bottom feed, but you might think about making one minus the feeder first.

This is for the one I mentioned above.

I won't be much help beyond this point LOL I am still a newb. Hopefully someone else can tell you about more regulators.

 

[bigv69er]

well im going to use a 3ml bottle so it will be small.. so i will have extra space.. so i have to get the four pin one.. to use with the small switch??

 

[Lazrah]

Yes, the reg you decide on needs to have a control pin for the switch to be connected to. I like these little guys, Tactile Switch with Round actuator, 300g.. I used one just wired in like a 3amp switch would be (without a reg) and it burnt up in the first night vaping at only 3.7v. I use another switch the exact same style one. Except I use a reg and vape constantly at 5v, the switch doesn't even get warm. Going on 1 1/2 weeks with it and workin perfect still.

 

[bigv69er]

What is the reg control pin for?

 

[Lazrah]

The control pin is where your switch is wired to. It will make it so hardly any current will pass through the switch.

 

[bigv69er]

Ah ok.. Then i will get it.. Since i am using that baby one. Lol
Already ordered my trustfire 14500 protected batteries

 

[Lazrah]

Nice! You'll have to post some pics of your work when you get it finished. Any more questions and I will do my best to help you out. If I can't I am sure someone else will help out!

Good Luck!

 

[bigv69er]

Thank you!!!!!

Excellent advice Lazrah! Although I'm by no ways an electronic expert, I agree with all the advice Lazrah has given you big. Even with using a 3mL bottle, you might not fit it and the regulator, switch and atty connector in the one AA slot. Like Lazrah said, place everything in the slot loose to see if it will fit.

 

[bigv69er]

Yeah thats what im going to do.. If it doesnt fit goodbye bottle lol
