Ultrafire 4200mah problems

[jpracing]

I bought a few Ultrafire 4200mah batts for my provaris
thinking that they would last longer for high voltage vaping
on my dual coil carts in tanks.
I haven't been able to test length of charge because when I
change voltage and press the fire button, my provari stops working.
I tried this on all 4 of my provaris and I get the same result.
However, once you change voltage, take the batt out, and put the batt
back into the provari, it worked flawlessly.
Any thoughts? Maybe you've encountered the same problem?

Are they high discharge batteries?

From what I read,those are preferable to higher mah even if their mah rating are lower...they give you more

 

[jpracing]

Don't really know if they are but I have used non high discharge batts before
and they never had this problem.

Anyone?????

I assume we are talking about 18650's

Where did you find Ultrafire 4200 mah batteries ?
do you have a picture of them?

 

[Sicarius]

Highest (true) capacity at the moment is around 3100maH so 4200maH was imported from the future.

That said and trying to understand the question maybe it's a ProVari thing. Reason I say that is try the following - when the battery is getting to low voltage condition (red light starts to flash) remove it and put it back in. Light stops flashing and you can carry on vaping for some time. It's almost like the electronics get a reset or something.

Do your PV's work normally with the IMR batteries?

That's the issue as I'm sure it would/does, These types of issues have been covered many times over on the forum along with the boost circuit technology covered in the link in a previous post. The recommendation for the Provari is IMR technology/batteries....AW brand specifically as that's what's been found by Provape to work best with the Provari I believe. Technically any IMR 18650 should work though.

Sicarius: Exactly on your second paragraph!

As to your first, I have been using 6500mah Lipo/Li-ion batts on my RC cars for a year or more.

Frick: Read it. Thanks

Slurp812: Yup!

Keeno: Where? I've searched. Nothing comes up.
And, yes, any 18650 below 4200mah works on all my provers regardless of them being high drain or not.

Why not use non IMR batteries in my Provari.....it works fine:

Because the amps are hard on the battery. The c rating of a non IMR battery is much lower then that of a IMR battery. You're pulling a lot of amps from these batteries, and IMR is meant to handle the conditions a boost circuit give.

I don't know what more to tell ya......just use what the circuitry is designed for and be happy I guess....or continue your experimentation with so so or unpredictable results depending.....hope you get it figured out.....

 

[jpracing]

Yes, I do understand what you have explained.
I am just asking the question because maybe someone has the answer
I'm experimenting on higher mah ratings, not cheap batteries. I just would like to go to the office with less than 5 batteries with me.

It's all good JP.......good luck.....

Kumusta jpracing...

mAH ratings on batteries cannot be trusted... cell quality is the key to success with your Provari, and the AW IMR batteries are the way to go... There are the new 2000mAH capacity AW IMR 18650s now, and they may well give you a little more run time...

The UltraFire batteries you're using sincerely won't be up to the job, and are misleading with their 4200mAH claim...

Ok naman. Ikaw?

And, you are correct. mAH ratings cannot be trusted. However, cell quality can only be tested if your charger has a balancing lead or balancer built in AND only if the batts aren't inline. I've got the balancing charger from my other hobby however batts for mods are inline and have no capability to be tested for cell quality. Not by me and my equipment, anyway.
This is why I went to mAH ratings and testing them out for run time and charging times and how much I can squeeze into them as far as mAH is concerned.

If they're protected batteries, it's the protection circuit kicking in on the battery itself. That's why they tell you to use High Drain IMR batteries, they do not have a protection circuit limiting the draw of the unit. I had this problem with the 3000mah Ultrafire BMR 18650s.

 

[Slurp812]

Take a look @ this yes, they are 18650's, but the same holds true for the smaller ones as well but to a lesser extent. Note the MAX DIS on the IMR battery. Not sure about the accuracy of this.

Absolutely on the money... agree 100%

Wow! 5 batteries? Are you gone for a week at a time, or do you vape that much?? Man I must be a real lightweight. My 18490s last me all day!
