SB Hot Spring & PT

[jasezero]

You don't NEED anything Pull out the spring with a pen and go into a room with good lighting. It will be copper in color

Weird...i must have some odd hybrid...i have the copper positive connection, and a silver spring for the neg...

guess im spending an extra $2 tonight =P

I got one SB with copper one with out, I dont see any difference in my vape at all ??

There is a slight difference in loaded voltage, ranging from .3-.5 depending on batteries and atty you are using. It does improve the lower resistance atties performance more tahn the higher resistance types.

I started using the same contact for the BB and SB close to the same time. I did however use the rest of the bushings before I made the change to the SB. The main reason for changing the positive contact was the SB pass through. The loaded voltage is only changed by .04v or less.

Well I ordered it anyhow...can't hurt to have two springs, especially if its only a couple bucks...

I also ordered the PT, drip tips, a 901 low resistance atty, and a pack of 510 cartos... =D

I don't suppose you guys would send one of these to Australia? I just received my BSB yesterday and it has the old style spring :-( I've been loving the BSB with an 18650/LR atty combo too, so the copper spring sounds great.

Does anybody know if the double barrel head will work on the SB PT?

If it has that copper colored positive contact it should. Same as the regular SB head.

 

[pudgey7]

my dbsb has been working on the pt for a few months

Curious what you're plugging it in to? I've got a 2 amp wall adapter and I'm also considering an enercell. Got my DBSB and will have the PT soon.

Just want to say this again. The copper colored contact is 100% compatable with the SB PT, the silver is a bit iffy. It is only iffy because of the hole in the center of the contact

That sounds great, Chains. Have you tested with standard Li-ion 18650's as well?

I just got a couple of AW IMR 1600mAh batts the other day and I've been pretty unimpressed with them. I don't have the know-how to test them under load, but even with LR attys they don't perform any better (with the old spring) as far as I can tell. They just run down and drop in vaping performance a lot quicker than my grey Ultrafire 18650's.

Anyway, I hope iVapour or the Canadian place get the copper springs in soon so I can get one sent out my way.

Will be a couple weeks out before they do, got about that long till i get them in my hands . I use the IMR batts and I noticed they improved after a few cycles. Is your 18650 a LC18650 or a TR18650?

I'm using LC18650's. My IMR batts still haven't been used/charged much, but I'll try and break 'em in a bit more before I totally write them off.

I noticed a diff in heat time, was not imressed with the life, that has however gotten much better in the month of using them.

I haven't tested with the TF 18650 yet, but will report back tomorrow on that (gotta run out for the night).

I'm actually using the IMR in place of the TF because it burns a little cooler with the LR atty, the TF gives more of a burnt taste especially if I take too long of a drag. I'm no batt expert, I expected a 'high drain' batt to spit flames with a low res atty, but it was the exact opposite. I like the IMR with LR because it's similar to my 5v regulated mods, they shoot thick clouds of vapor with full flavor, but no burnt taste. I just couldn't get used to the messed up flavor of LR + TF 18650 and 16340.

Don't forget, the battery isn't "pushing" current. The atomizer is "pulling" it. The only way a "high drain" (translation: high maximum discharge rate) will make a difference is if your regular battery isn't capable of supplying the current draw. They should very much be able to supply the rated max discharge rate and usually much above that. So... the question is: what's the max discharge rate on the TF's? I'd expect it to be 2C or better? (hmmm, appears to be 1.5C). 2400mAh at 1.5C would be about 3.6 Amps? and I'd expect them to do better than that in a pulsed application maybe? I guess that would depend on the trip point for the pcb?

Using the IMR numbers

3.9v @ 2.2 ohms == ~1.8 Amps
shouldn't be a problem and you wouldn't expect to see a difference?

3.9v @ 1.8 ohms == ~2.2 Amps
Still shouldn't be a problem.

What I don't understand is why you're seeing a voltage drop with the stainless spring? Was it just the battey voltage tapering off because of the previous test's usage? More resistance with the stainless spring, the current draw should have been even less, so potential for voltage drop less as well...

I mean, I am under the impression that there is some small voltage drop between resting and loaded (due to internal resistance of the battery?) but outside of that I thought you should only see voltage drop if the battery wasn't able to meet the current demand. Then you would see a voltage drop to balance Ohm's law equation.

Its kinda like this, you need to satisfy the whole ciruit.

Atomizer = 2.2ohm
Spring = .3ohm
Working voltage = 3.7

3.7v/2.5ohm(2.2+.3ohm) = 1.48amps
I X R = V
.3ohm(spring) x 1.48amps(circuit) = .44volts
This is almost exactly the difference under load in bench tests with a 510 atty.

doh... now you have to explain why you went to volts for the spring. I thought batteries would maintain their voltage until they couldn't supply current at the rate demanded. or is it a bit of both? the battery supplies most of the amperage demanded and the voltage drops to compensate for the rest? How's that work?

My WAG was that a battery should be able to supply current up to the max discharge rate without any significant voltage drop. Even more but (without a circuit) damage or bad things might happen due to heat? Is heat the missing variable? or that the chemical reaction can only take place so fast?

don't make me have to actually expend effort to google this or something...

Every component in a circuit consumes voltage, unless you use a PWM to regulate the voltage.... but it still uses voltage.......hmmmm.
