Battery Question ( repost)

[whitezyzz]

So my batteries have been working fine ever since I got them but now something has happened that I dont understand. I have a trustfire charger (not the best I know) and some trust fire batteries. Right now in my provari I have a trust fire 18500 and it works fine. With the extender cap I stack two 18350s. These batteries started to die so I put them on the charger as I usually do. I noticed the charger was getting hot by the main connection but the whole unit wasnt hot. While the two 18350s were charging, I also noticed they were getting a bit warm as well. When I put my nose very close to the batteries, I noticed a slight plasticy smell, it wasnt very noticeable until I put my nose close to it but it was there. On top of all of this, the charger would charge for about ten minutes then short out. This has never happened to me before so I am unsure of the problem. I took the batteries from the charger and unplugged the charger. The batteries are not melted in any way and seem fine but I am worried what is going on. HELP

I would stop using that charger and buy a better unit.

Stacking batteries in a Provari is a very bad idea.
The extender cap is for use with one 18650 in a standard size or one 18490 in a mini size.

Theres a bunch of stuff wrong with this post. First would be the warranty will be void if you damage the unit with the trustfire battery. The recommend the aw imr a.k.a. red jackets. Second is do not stack batteries in the provari. Battery stacking is a bad habit to do anyway. Especially with low quality stuff with fire in the name. You should get rid of those batteries and charger. Those are low quality batteries and you dont want those to go thermal while next to your face. Get some aw imr and a nitecore charger. I am sure baditude will be here any minute now.

You've got a LOT to learn about safe use of batteries!


Stacking batteries is HIGHLY NOT RECOMMENDED.

It is stated in bold print 3 times on the Provari page "We recommend only using AW IMR high drain batteries in your ProVari"

"Batteries - We only recommend using approved 18490 and 18650 batteries in the ProVari. All of the batteries that we sell on our website have been tested to work with the ProVari and these are the only cells you should use. There is a big difference between all the different batteries on the market and a lot of testing has been done on these various batteries. The reason we recommend using high drain cells is because these cells can output more current providing the ProVari with the power it needs to operate properly. There are a number of batteries that will cause issues including the Trustfire, Ultrafire and other brands. These batteries cannot handle higher current output and the battery will turn off while in use or cause a low battery alert much sooner than it should because the batteries have a high internal resistance. Please make sure you get the proper batteries to use in the ProVari to avoid problems."

The Trustfire 18500 battery that you are using is a protected NCR li-ion battery, totally inappropriate for a Provari.

AW 18490 IMR battery

AW 18650 IMR battery

​

You should be ashamed of yourself to defile the Provari. Your Provarinati membership has been placed on indefinite probation until you get the appropriate batteries.

From Provari Manual:
"Note: The ProVari operates on a single battery. Never stack two batteries or use batteries that are not
recommended for use in the ProVari. We recommend you use IMR high drain 18500 batteries or IMR high drain 18650 batteries with the optional 18650 adapter"

Also not supposed to use Protected batts in a APV.
TrustFire batts and chargers are low end quality and many of us (myself included) have had overheating/ failure issues with both TF chargers and batts. Lastly but most important besides the fact you're not supposed to stack batts in a Provari there are a number of specific safety procedures to follow in regards to stacking batts otherwise it can be quite dangerous.

Do not do that again!!! The Provari is not designed to stack batteries in.

These batteries started to die so I put them on the charger as I usually do. I noticed the charger was getting hot by the main connection but the whole unit wasnt hot. While the two 18350s were charging, I also noticed they were getting a bit warm as well.

I strongly suspect those batteries are bad now. I think if you have a digital multimeter you will find they have very low voltage and may have reversed polarity. Do not try charging them again unless you know they meter a proper voltage above 2.7V. How do you know the charger was shorting out? What did it do?

Yes, that is a low end charger that is really not very good. It can't handle anything out of the ordinary. Do not try charging anything in it unless you know it is good.

Please do not put your nose close to a charger that is heating up with batteries that are warm in it. Either the batteries or the charger could have exploded and your nose would not have enjoyed that!

Doesn't anybody work or sleep around here

 

[Ryedan]

Nice to see we're all thinking alike here. I can't believe the Provari fired at that voltage .. Has anyone heard that it can before?

 

[Katya]

Oh dear...

Dear OP! Please throw away that charger and batteries (or use them in your flashlight).

Buy a good smart charger like Nitecore, Xtar or Pila and buy a few AW IMR batteries 18650 and 18490.

Genuine AW Batteries at RTD Vapor

RTD Vapor is a great place to buy batteries and chargers. You can also try Amazon--I've seen good deals on Nitecore chargers, but do not buy batteries on Amazon or eBay or such places.

And please read the ProVari User's Manual...

Bwahahaha... Your Mayor has been on the news here a lot yesterday.

And I thought, "You put your nose where? NOOOOOOOO."

Hopefully, this will be sorted out quickly with no harm to anyone.

Question? Are there *any* APVs that actually allow or suggest battery stacking? Other than some weird mechanical mod perhaps?

I know the Vamo does. It's the only way to achieve maximum power with it. The Zmax might also, but I'm not sure.

It would seem to me that if most all do *not* allow/suggest battery stacking, could it be a risk, even with a unit that does allow/suggest it?

 

[Vapoor eyes er]

I've stacked batts in my Vamo V2 and V3 and a LavaTube BUT realize it's not a safe thing to do. Also have to keep a close check on batteries being used and alternating them each time and testing them continually. Eventually stopped as it wasn't worth the hassle and risk.

I don't do it so I have not looked into it Peter. It does involve increased risk with mechanical mods that have no protection built in, but not sure about the regulated mods like the Vamo.

Getting back on topic, it is a very risky proposition with a mod that isn't designed for it.

ETA: You posted while I was typing Vapoor eyes er. Thanks for the info!

It's OK if you know what you're doing. Interesting read on the subject:
