TI booster with 14500

[UberSquid]

I read somewhere on here that the TI booster would not work with a 14500 battery. I have a handful of boosters and was going to try and stick one in a 2AA box with a 14500. If it won't work though, I'll order a 3AA box and run two batteries in parallel.

Thank

no,

Quality 14500s work with the TI booster---- e.g. AW brand

Observe :

I've tried to get them to work reliably but the current, even in an unprotected bat, just won't keep up and there is measurable voltage drop.

The smallest bat that can keep up to the current drain required even at 5v was an 18500.

You will need 2 in parallel to maintain 5v under load.

I see you aren't running the caps on your board, have you had problems with it?

Is there a posting anywhere that shows how to wire the TI booster? I've been looking at them and I'm a bit confused as to where you are supposed to solder the leads.

You definitely need the caps if you want stable voltage and to reduce the peaks in current drain from the battery.

The wiring for base 5v is pretty simple:

The base is ground to pin 1, voltage in beside it (short side) and voltage out on the other side of ground (the long side).

You need a 100 uF low ESR cap between ground and Vin and another between ground and Vout.

No biggie,

But I've made quite a bit more than a few of these mods, some with caps, some without, some with one...etc.

And have not noticed any difference in performance.

I currently use two different bats, one trustfire the other AW brand of 14500 3.7....

they both work just fine, though the AW brand work for twice the time.

4 hrs. of heavy vaping for the AWs and maybe just two hrs, for the trustfires...

Call me lucky, or just to stupid to know better---but it's the best set-up for smoking cartomizers I know of...

Right-on
Rock on with your switch down

PS. there's a PDF data sheet on the ti part # page---all is reveled to the reader...

but yeah ground to the #1. leg VI below same side--VO opposite the 1. leg.

Data sheet! Stoopid! Thanks guys for the help. I've got my 5V TI mod up and running now with a DSE801 atomizer. I LOVE THIS THING! I always liked the 801 but felt like it was underpowered, not any more! Tons of vapor, great flavor, huge cart, this thing is awesome! It does pig out on the liquid though and I actually made myself a bit sick by using it too much last night. That never happened before with the lower voltage mods.

I'm running two UltraFire 14500 batteries in series. I didn't bother to put the caps on for the first one as I was running out of space. So far I've had zero problems with the box but I will be putting it on the oscilloscope later to see what the output looks like and make sure that I'm not going to start trashing batteries. So far though the temp probe I hooked up to the batteries shows very little rise in temp and the current flow seems pretty stable. I doubt with the short duty cycle that any spikes in current draw will be an issue but I am curious to see exactly what is happening on the output side of this board.

Thanks again to everyone that helped!

In series would give you about 8.4 V in and would require a voltage regulator as opposed to a booster... Did you mean parallel?

 

[UberSquid]

Yes, parallel! I've learned two things with this project: One, don't solder or lay out circuits when sleep deprived, it leads to ruined components and second degree burns. Second: don't post after you finish your mod and are even more sleep deprived as you will make stupid mistakes in bragging about your new mod and look like an idiot.

Thank you for the lessons learned

 

[FlipnOut]

Soldering iron burns suck! Glad to hear it was parallel, I'd hate to see you let the magic smoke out of that complimentary TI board.

Here is a stupid question for you all. When installing a TI booster do you use a seperate ground wire or just link in to the negative wire from the batt to the connector?

Makes no difference...it's a common ground in either case.

where can i get this TI booster and what good will it do for my mods?

 

[supertrkre2812]

You can get them here.
Plug-in Power Modules - Non-Isolated POL - PTN04050C - TI.com
you can get free samples by jumping through their hoops, get 1 of each one offered.
The only difference is how you connect the wires, or mounting.

There are a few advantages, the biggest is that is turns a single battery into a 5v+ mod. Because its a single battery it also allows a USB charger to be added easily.

Assuming you use a protection circuit it also is inherently safer than using a 2 bat in series solution for higher voltage.
