Voltage Of Two 3.7V batteries In Prodigy V2

[rfw2003]

I don't know how there can be any resistance in the contact discs. I just busted out my multimeter and w/ out an atomizer it was reading 6.6 volts.

Just like any electronic circuit you won't see the voltage drop through the resistor until you have the circuit complete. Your VOM does not complete the circuit it just measures voltage potential. Plus with just the resistor itself and nothing else you will see the full voltage of the batteries across the resistor itself instead of divided between the Atty and the resistor. When you have 2 or more loads or resistances in an electrical circuit that is when you will see the voltage drops in the different areas of the circuit.

Ok that makes sense. I just seen that under load the V2 puts out 5.15 too.

It shows that you have a very limited knowledge of electronics, with all due respects. .3ohms does not amount to ..... .3 ohm resistance is rediculously small. Most test leads have that much resistance especially the cheapies that is why they have to be deducted from the reading. The disc they use was from a piece of printed circuit board. Some printed circuit board traces look kind a grayish. That is probably most people think it is sort carboned-up alloy. Sorry, I don't mean to insult anybody.

Shows how much you know Nico, as this is not from a printed circuit board, it is in fact a titanium alloy, which is a piece of metal. Titanium has a higher electrical resistance than that of aluminum, copper or stainless steel, that is why he used it to provide the resistance. Using that with the combo of the aluminum contacts in the beginning of the switch gave it a total of .5 ohms resistance, which if you knew anything about electronics you would know that, that is all that is needed to limit the current with the side effect of dropping the voltage down to in the case of the true Joye 510's 5.8149 volts under load with fully charged Tenergy LiPo4 batteries, Now with 3.2 Ohm BE112's the Under load volts would be 6.227 volts with fully charged dropping to 3.8 volts under load just before the cut off on the Tenergy batteries Mind you these voltage numbers are based purely on the calculations with a bench power supply not with actual batteries, the voltage under load would be somewhat lower with the batteries due to the resistance of the batteries themselves. It doesn't take much resistance to limit the current to what would indeed be that if it was running off off a 5 volt regulated power supply. But as anyone with any background in electronics knows voltage here doesn't mean much of anything when you introduce resistances into the mix as resistors are more of a current limiter then a voltage limiter. Sounds like you are the one that needs to brush up on your knowledge of stuff before going around making accusations about stuff Nico, instead of trying to bring a company down with misinformed information That you apparently have know knowledge of.

I'm sorry all for the vent here, but individuals that are malcontented with misinformation in the intent of tarnishing other people bring that out in me.

As another note:

As far as aluminum being used, I thought you mentioned you have been in the electrical field since 1965??? I guess you are the only person out there on this Planet we call Earth that has not seen aluminum connectors then in the electrical field ever.

Nico,

The V2 does use a resistance material for the contact disc. You can verify this with any VOM. It is an Alloy metal that has a resistance of appox. .3 ohms. The reason They switched out the aluminum posts to SS was to stop the natural oxidation issues that are common to aluminum that the SS doesn't have. Did we have to pay for that as consumers no. PS sent that out for free to all that bought the Prodigy's and Protoge's. As far as using a switching module or mosfet to switch for the switch the reason he did not do this if for reliability and simplicity of the design and also to allow user serviceability of the unit. with a soldered in piece it of electronics not only does it make it more prone to failure over a mechanical designed switch it also makes it where to most people it is no longer user serviceable, plus now it's just a switch that turns it on and off and does not drop the voltage down unless you also add a voltage regulation unit to it as well. But don't be discuraged as soon they will be stoping the 5v only and going to 3.7V devices with low resistance atty's and doing away with the alloy contact disc that is the main issue with the complaints on the switch. The newest designed mechanical switch on the Protege is working wonders with the SS contacts and copper disc. Myself I have no issues on my V2 with the Alloy disc and SS posts at all. When I had the aluminum posts I would just use noalox on them and do a weekly cleaning on it and had no issues at all with that. It's all in the maintenance. If you want a maintenance free device go with the cheap Chinese crap that fails a few months down the road because they use under rated batteries, and electronics that can't keep up with the current demands that our atty's require. If you want something that will last go with American made with a mechanical switch that just needs a light maintenance schedule, to keep working in top form.

I have said my peace now and will post no further on this issue

Comparing the V2 to a Chinese model doesn't say much. Let's compare it to the GG as just one example which works flawlessly. And on the issue of maintenance, it might have been better customer service to explain that constant maintenance was required, upfront. And it is nice that the new Protege switch works so well. How does that help V2 owners?? So those of us who bought a V2 are just out of luck based on your post.

I believe that Steve will make this right but making excuses doesn't hold much water IMO. As a consumer, a product should not require constant "fiddling" for it to work intermentently.

I'm not saying anything of the sort that those with the V2 are out of luck, nor am I saying that it needs constant fiddling to keep it working either.

As for comparing it to the GG the V2 needs no more maintenance then it does. If you go to the GG's main web site you can see for yourself on that issue and download the maintenance guide for it and it outlines exactly what you need to do for normal maintenance on the GG which is no more then what I am saying with the exception of putting Noalox on the switch as well so you don't have to lap/sand the switch contacts all the time like they recommend at every maintenance interval with the GG.

The Pure Smoker Team unlike other companies are going out of their way to try and find materials that do not tarnish/oxidize during the on going evolution of their products where as everyone else seems to be sticking with brass or copper as the sole material for the contacts in their mechanical switches which does require a regular maintenance schedule.

So as you see I'm not making excuses I'm just pointing out facts that everyone seems to want to over look because Pure Smoker has become such a growing and popular choice in this very fast paced new industry.

+1 I can't think of anything man made that doesn't require maintenance.

i own 2 Prodigy, both 901@ 5 volts. 1 was a pre-order, the other bought a month later. i have not removed the atty end-cap since i got them. never cleaned switches or disc's? i use empty carts, everything i vape is drip. i am sure i have used at least 1000 ml of juice through these units.
Steve, you make a fine product. keep up the good work
