LOL ... ecig stealing to get data ... I like ...

haha ...

Robw,
Please don't take this the wrong way but you are completely missing the main thing here. Batteries have an internal resistance that causes their voltage to drop WHEN UNDER LOAD. All the batteries will drop voltage when you measure them inder load. off load voltages are not relevant.

Also the concept of the voltage being spread around the bridge is a new one on me. The voltage heats the little coil that you can't see, under the bridge.

you could also compare results from atomizers made by by the same manufacurer and get wildly varying results, the manufacturing process tolerences are far to big in these things to give a real consitent part.

Also there are 2 models of atomizer , an 'RN' series atomizer and a 'DSE' atomizer both marketed as plain old 901 atomizers.
the most common type are the RN type..

the the dse type have a more pointed wire wool bridge.. the RN type a flatter bridge.. the RN type also run noticeably hotter..

errrr. your reasoning is kinda way off robw..the voltage for a screwdriver battery depends entirely where the charger takes it to...

normally the safe point is around 4.2 volts.. this initial voltage drops off as the battery runs down.. by the time it gets down to around 3.5 volts its time for a recharge..

this applies to pretty well all e cig batteries.. the screwdriver battery is simply bigger.. it has less of a voltage drop under load and will give any atomizer fitted to it more power than normal small e cig batteries.. it also dose it for longer..

the wire wool bridge.. its simply there to wick fluid from the cart wool to the wire wool that feeds the atomizer heater coil it dosnt do much else..

atomizers have change slightly in design.. i think u have some different time period ones in your pics.. we have shipped three different types (shapes) in the last month..

a copy of an email i just sent to a customer..

there are two types of a 901 atomizers xxxx.. the original DSE 901 type and the RN type both come from different chinese factories..

now this is where it gets complicated.. we have supplied both types with our screwdrivers.. the RN type like the ones from pillbox run a little hotter and produce the most vapour.. the DSE type run a little cooler.. atomizers can vary a lot as regards how long they last.. some simply just stop working some just fade away..

to know which type you have look down the end at the wire wool bridge that sticks up.. the latest DSE type has a more pointed bridge.. the pillbox RN type a flatter bridge..

the DSE type can be obtained from eBay Store - elecitronic cigarette: e-cigarette, ruyan, e-cigar

we are now shipping the RN type.. shortly we will offer them for sale in packs of three or four for around £20 plus postage..

when they start to fade off a little too much.. press the switch for around ten seconds and heat them up till they glow.. look down the end while doing this.. remove the cart.. it perks them up for a bit longer but it also might kill them of completely.. so be warned.. put three or so drops of liquid into the atomizer after cooking it..

atomizers are simply a consumable just like the liquid is.. we make this clear no one else does.. they just need to be obtained cheaply and replaced when needed..

best of luck

anyways your reasoning is off... but we all have to start somewhere

just to add.. the latest DSE cooler running ones seem to have more wire wool around the atomizer pot.. also a slightly smaller ceramic pot the heater coils sits in..

i think this is to help feed the heater coils better but it has the downside of being too easy to flood when it gets too wet.. add in the less hot heater coil and the fire goes out so to speak.. they probably work better with just a cart and might live longer but dont like being wet..

swings and roundabouts.. compromises and a very inexact science.. this is what e cigs are all about..

All very good pieces of information.
If I understand correctly
The taller bridge one is the DSE. (smaller core/cooler running/does not perform well when flooded)
the wider bridge is the RN (older model/hotter core)

The descriptions counter the evidence from my tests.

In my test the DSE ran hotter on the dse battery than the RN.
On the screw driver, the RN ran better than the DSE

Could it be that the DSE is better at being a dripping model than the RN? Because the Test were all done dripping.
Im going to try just carts one both atomizers now to keep them both from flooding.

[robw]

Im writing this experiment in real time.
Ok Im using carts not on both the DSE on a DSE battery and the RN on the Screwdriver.

I started each off by blowing them out, and putting identical factory carts on both.
I let both have time to wick the liquid down and both have fresh charged batteries.

So far the result is:
The DSE and the RN perform identical on the first few puffs.
After 4 puffs the RN continues to draw constant fluid from the cart while the DSE is starting to dry.
Waiting a few min.
It took a min for the DSE to re wet it self. Could be the distance the fliud has to travel (extra 3mm wich height)
The RN is still wet
Swapping RN and DSE. Now RN is on DSE battery and DSE is on the screwdriver
DSE on the screw driver gave 3 puffs before it ran out
Did 8 puffs on the RN on the DSE battery and it is still wet and working.

I think we are finally seeing the difference here.
In my experiments last night all the atomizers were dripped.
In the drip method the DSE performed better than the RN

In this new experiment with using factory carts, the RN performed perfectly while the DSE required time to re wet after 3 puffs.

I will pick up a larger sample of atomizers and verify the tests at a later date.

[trog100]

we have decided the RN type are the better ones.. which is the ones we will now ship... i would suddest useing the screwdriver in your atomizer tests for one simple reason.. it will give consistent power to the atomizer..

normal e cig batteries are all over the place and unless brand new will give variable results.. even brand new ones will give variable result..

I wanted to chime in and say I'm pretty sure Yang's 901 uses a different type of atomizer.

[robw]

I agree that Trog, the RN atomizers when used with a cart perform perfectly and consistently.
Dripping into the cart works better than dripping into the pot in the case of my screwdriver.
