Suggestions for 5v batteries and cases

[kardjunkie]

I want to build a 510 mod. I want 5v and supper long battery life like over the 2000 mAh area. Any suggestions on battery configurations to use and how to get the voltage at 5v? And any flashlight cases that will fit that battery and have space to get the 5v i want? Thanks for your suggestions and time!

Tricky.

2000mAh's . . . you'd be looking at the 18650 li-ion's, without a doubt. For 5v's, you'd need two of them (7.4v) with some kind of voltage regulation circuit in place, usually a MOSFET. I've never wired one, so I couldn't tell you the process to do so, but that might help you get pointed in the right direction, or someone else might chime in with more help.

Two 18650 batteries for 5V in line to fit in a flashlight would measure a little bit over 5 inches, no regular flashlight will fit them although you might find a few but at a very high cost, not worth for a mod.

I made myself a 2 x 18650 box that i use as a power pack but it is not at 5v it is at the regular 3.7v

Would something like this work
DealExtreme: $19.47 3500mAh USB Emergency Power Battery Pack with Cell Phone Adapters

Take it apart, the output of whatever your charging to the atty, put in a different case. It's like roughly 3" by 2 3/4". I guess my real question would it power a atty?

Just looking to much at DX and kept seeing them and thinking of the possibilities with something like this if it would power an atty.

Model: MND0608000-11- Capacity 3500mAh (manufacturer rated)
- Input (charging): 5.3V 600mA
- Output (discharging): 5.5V 400mA
- Cell phone adapters included (see pictures for comptability)
- Perfect for cell phones, PDA, MP3/MP4, game devices such as PSP/NDS (optional cables required)
- 100~240V AC Charger included

No, it would probably detect over current and shut down if it's properly protected.
I have a 500ma unit that shuts down immediately if you try to power an atty.
My 1500ma Kensington works fine though

-Actually it probably would work if the atty is powered by the battery while charging. Sorry I misunderstood. It just wouldn't power an atty directly.

I haven't seen anyone try a 5 V voltage regulator yet

SparkFun Electronics - Voltage Regulator - 5V

Here is a 5v regulator I just finished today. It is fantastic.


TI # UCC383TDKTTT-5G3

Wiring is not very organized yet. I just installed the regulator 30 mins ago.

 

[cybervex]

Output is a constant 5v till the batteries get down to <5.5v which is the minimum needed for the regulator to function.

Both the atty and the regulator get quite hot so you cannot constantly vape but the vapor output is thick enough that your do not have to.

I have made them with the same regulator. posted here in the modders section as well. TI will send you five for free ( more than once too) if you want to try them out.. they do work great!

Same way I got them. Up to 5 at a time for free and shipped FedEx for free.

Where did you get that switch from?

 

[cybervex]

Where did you get that switch from?

One of the engineers I work with gave it to me out of a spare parts box. Pretty sure it came from digikey, mouser, or newark

I usually use Radio Shack part# 274-0644 for my mods

 

[kardjunkie]

Where do you get the regulators at?

 

[Shreck]

Where do you get the regulators at?

Texas Instruments, read whole thread and it will give you part # at post number 7.
Go to TI.com and sign up, search samples for the part# and order for free. simple as that.

 

[Shreck]

always make sure to install the regulator AFTER the switch, because the regulator is hooked to your ground as well, and if it is before the batteries it will start working as soon as you put the batteries to it.

Just ordered some of the regulators , Thanks for the info.

 

[kardjunkie]

Yes, thanks for the info on the regulators I ordered some today also. Thanks!

Hey cybervex - it is possible to get a couple more pics showing the regulator connections a bit better?

nice switch, very hard to work with after a couple of hours of heavy vaping though

wow it even ships overnite Free! Now i need to buy a soldering iron and figure out how to wire this thing!
