on li-Ion batteries when the voltage on the battery gets to a certain low point the PCB shuts it off...

the high drain doesnt have that so you wouldn't run them til they're dead...you'd switch them out when the vapor gets weak..

is safe chemistry better than PCB...that's more a personal prefference what you're comfortable with kind of thing...I think so..

yep they are not protected so you could damage the battery by draining it too far down.
so buy a multimeter, and recharge often and you'll be fine.

I really like this battery, as it has enough discharge rate to keep up with LR atomizers and has a protection circuit to boot. I test fit one in the Precise when designing it too:

No more high drains for me. The ones I bought cost twice as much and last half as long. I don't see the advantage to that.

My results using AW 16340s are not at all consistent with yours. What brand and model of high drains have you tried?

The BUZZ, from Notcig :thumb:

Did you test them with a Buzz? Their advantage with mechanical PVs may not be realized with voltage regulated devices like the Buzz where the regulator controls the show.

I own four chargers, a trustfire Tr-001 that i use for all 3.7 volt batteries (my mom has one too thats been going strong for a good year now). I also have one for CR123 3.0 volt style batteries and one for CR2 3.0 volt batteries. I also have a nano charger for 3.7 volt 16340's, but the TR-001 charges those too, so it isn't necessary.

I'm thinking I want the IMRs mainly for the safer batt chem.
but why exactally are they safer?

I recharge often so since they are non-protected isn't much of an issue for me.

"Do not short circuit ( will release tremendous current)"
alright so AW says this will happen.
does that just mean it will shock the piss out of you?
I want to know what to expect if a short circuit did happen.

-New Anti-expolsion Vent/PTC Module : the new module provides an added layer of protection against gas built-up in addition to the PTC thermal protection. Unlike regular vents used by most LiIon cells, these new modules will actually stop the action by separating the electrodes inside the battery when the pressure reaches a pre-set threshold. The vent disc will open and release the gas plus stopping the cell from further chemical reaction. Combined with the PCB electronic protection and two layers of mechanical ( thermal and pressure ) protection, these new protected R123s are the first with these added safety features in place.

My understanding it it applys to all AW LI Ion batts.

It sounds like we can rely on this feature in vented PVs like the T-1 and T-6. I'm not hopeful that any unvented PVs will have enough open area between parts to take advantage of this feature, IE; battery vents, venting gas into a closed chamber.

How exactly does one short circuit a battery? Which measures do you have to take to make sure that doesn't happen? Thanks.

Short circuit - Wikipedia, the free encyclopedia

A "short-circuit" across a battery is when the positive side is electrically connected to the negative side with no resistance in between. So touching one end of a wire to the positive terminal and the other end of the wire to the negative terminal would be an example.

Don't do that! If you short a protected battery, the PCB should figure that out and "open" the circuit for you pretty fast, but still the chemical battery will be unhappy about the "short" put across it. If you short an unprotected battery, its going to drain really fast and heat up quite a lot and who knows.

Don't stuff metal bits (foil, tiny bits of staples in efforts to extend the center post higher) into your atomizer adapter that could cause the center post to be electrically connected to the threads. Avoid using conductive grease (like noalox) in that area for the same reason. Current will flow thru noalox.

Don't stuff metal bits (foil, battery spacers) around the positive terminal post of the battery housing that could be electrically connected to the 'negative' body of the battery housing. Be very careful with conductive grease in that area too.

Another very common way to SC a PV is to overtighten an atty, which will push the center connector through the insulator and direct short it to the outside housing of the atty. (that's what the little rubber sleeve is for on the bottom) One more reason I'd stopped using TW 901's in the past.

I've seen this user error happen a lot in the past with a very infamous tact switch. It would immediately short/arc the switch.. Not only would the batteries heat up until the atty was unscrewed but it destroys the switch assembly.

Flooding an atty will have a similar effect (while not nearly as dramatic) and quickly drain your battery. The user notices a reduced amount of vapor and possibly a warmer/hot battery tube.

My understanding of their built is that their is a dble protection circuit, and internal one which prevents thermal run away and a external one that prevents explosion. Most batteries only have the latter when protection fails. Regardless if a battery is to vent any device without vent holes has the potential to become very dangerous.

Thnx for this info! I hadn't considered that overtightening an atty could distort it such that it could short out... nor that liquid alone pooling in the adapter could close (if not outright short) the circuit!

Since I generally don't use protected batts (i use IMR/LiMNs with LR attys) this type of info matters to me all the more.

I wish all mods had vent holes.

if anything it would atleast make me feel a little better.
