AW ICR123 Protected - Different Voltages at cutoff

[casualuser]

I could use some help.

I just started using AW ICR123 Protected batteries in my 5v Mod (mod limits to 5v) with a 1.8ohm Atty. I'm pretty sure I tripped the protection circuit on one of them. I took out the batteries and one reads 3.28v and the other reads 2.98v which I was shocked about bec they were both equally charged to 4.2v. I typically use the AW IMR unprotected and they have always drained pretty much equally.

Does anyone know why this happened to the protected batteries? Is it common for them to drain unevenly?

Unless you are running a parallel circuit in a buck and boost system, the battery closest to the source (load) will always drain more. make sure you rotate them. It has nothing to do with ICR or IMR. Also make sure your batteries are kept in sets.

You definitely tripped the circuit on the 2.9V one but should be good to charge.

1: You don't state it explicitly but it sounds like you are stacking batteries.
Please clarify whether you are stacking batteries.

2: What does "5v Mod (mod limits to 5v)" mean?
Is that the minimum input voltage accepted by the Mod?
Is it a home made mod and that's why it has no name?
Or is that the output max voltage of the mod?

3: If you are stacking batteries are you following the stacking protocol?

ICR batteries are not recommended for vaping.

I'll be more clear. Yes I'm stacking batteries in theis mod. It's a Smok Woo... it's 5v regulated so when I stack 3.7v batteries it comes out to about 5.75v (on the multimeter) I have a 1.8 ohm eVod tank on it.

It might be to much of a load for the ICR batteries. When I use the IMR high drain the voltages are pretty much even. Can you review the stacking protocols again?

There not? Mind explaining why? Unprotected I can see, but protected in "normal" applications they are fine. AAMOF outside of venting with flames when they fail vice just venting, the do protect the over zealous uninformed yahoos out there, by shutting itself off.

I'm surprised you are not popping your coil @ 5.75V. You should be looking at 2.5Ohm (longevity) 2.2Ohm will do the job though. BTW your set up is drawing 3.2A battery cut off is 3A, so yes you are stressing your batteries, especially the one closest to the load. @ 2.5Ohm you will be drawing 2.3A, better suited 2.6A @ 2.2Ohm.

Stacking protocols:
number your batteries
always use then and charge them as a set
rotate your batteries e.g 1 closest to the source this time, 2 the next and so on.

Thanks switched. I think I'll stick with the 16350 IMR high drain batteries instead. The 1.8 ohm coil has been working great with nice warm vapor. The AW protected ICR123 is only rated for 1.5C so I think that was my mistake.

Smoktech woo
Electronic Cigarette...

This unit performs at 5 volts with 2 16340 3.7v IMR Style Batteries (Protected Style Batteries will not Work). It has a eGo style head and 5 click on/off button.
Recommended dual coil 1.5ohm or single coil 3.0ohm or higher cartomizers or atomizers

Pretty unusual; I'm sure somebody else has one.

 

[casualuser]

Its my favorite device ever...and I've owned quite a few. Protected style batteries will fit and they'll work. Its just not the best idea if you're drawing heavy current.

Unsafe chemistry batteries are made with a protection circuit built in and sold as 'protected' batteries.
Safer chemistry batteries like the IMR batteries do not require a protection circuit.

I suggest you read Battery University my friend (my source) not some thread on ECF. Although not necessarily required on IMRs, all Lithium batteries should be protected.

The wording that you have quoted here if it appears as is (e.g not your wording) leaves a lot to be desired. Prior to IMRs that is all we had ICRs, and yes an ICR should not be used without a protection circuit.
