Joyetech Evic VT 60 Watt

[cigatron]

A series config ypur speaking of would last longer than a parallel at a feasable wattage, same 3 packs.

If you vape say at 50w the total amount of vaping from the 3s 1500 @11v would be equal to or More than the 3p 4500 mah @3.7v

Yes the 1500 mah at 11v is will last you longer than 4500 at 3.7 At 50w!

Why. Do the math, at 50w the amperage load on the batteries with 11v is a fraction of that with 3.7v.

I respectfully disagree with your math.

50w with 3 1500mah in series at 11.1v:
50w ÷ 11.1v = 4.5amps drawn from each cell because they are in series and do not share current load.

50w with 3 1500mah in parallel at 3.7v:
50w ÷ 3.7v = 13.5amps but because the batts are in parallel they share the current load so 13.5amps ÷ 3 = 4.5amps.

There is only so much juice in each gas tank. It doesn't matter whether the tanks are connected in series or parallel you will run out of gas at the same distance down the road all other things being equal.

That said, this does not account for the fact that tc mods requiring higher voltage inputs run more efficiency. They do and are they are capable of running higher ohm builds at higher wattages but all at the expense of current. This holds especially true if you run batts in series that have less than perfectly matched internal resistances at higher wattages. Each batt in series has to pass the current from the proceeding batt and if it's internal resistance is greater than the proceeding batt it will drop more voltage and create heat. That affects efficiency because that heat is wasted energy. Series configs are fine but the batts need to have closely matched IRs to stay cool and efficient in high current applications.

I didn't do the math on it at the time but yeah, it still works out to be the same on paper whether its rated 1500 mah,11v or 4500 mah,3.7v .. right.

Your figuring the exact same run time right?

I guess that was the main point I was trying to make, they are equal in run time... And most likely it still holds true today that a step down will be much more efficient than boosting so that's were the added bonus in run time comes from when compared side by side a more efficient process with come out ahead.

Now where I did go back to was older mods, specifically a sigilei chip in the zmax. That where I did lose you and go off the topic. That was comparing a single cell to a dual cell. So yeah.


But in the circumstance s I did achieve 2.5 times+ longer life, without the normal voltage drop, from the series 18350 850mah. Part of it was older batteries weren't as good, and the chips weren't as efficient. The 18650 of the time would sage badly under 3.6-3.5v and wouldnt power it fully, so you'd start to lose ouput and have to drop in a fresh battery to maintain voltage... But man that V3 ran great with 8v input, stepping down, and running maxed out at 6v to 1.3 ohms. . I was going through 3- 18650 in a day and one stacked pair lasted more than a day.. That's where I get the 2-3 times longer idea, it was I promise, as crazy as it sounds.

Times have progressed quickly, the common technology and batteries are so much better today.

Yes, in that case you were losing voltage potential with batts in parallel, essentially not being able to use all the mah from them because your build and mod required the batts to be more than half charged. The series config kept the voltage potential at double compared to the parallel (or single config) and allowed you to use all of the usable mah contained in each batt.

 

[JeremyR]

Back then it was great.. But yeah I went from talking 3s lipo vrs 3p, to single imr vrs stacked imr. The cool thing was I got all that potential from roughly the same size battery. The stacked 18350 were only like 2 mm longer than 18650 and had double the potential in vaping.

That can't compare to the lipo and the flat discharge curve is one thing I love about them.

Has anyone had any issues with charging?
I had my VT about 3 or 4 months now and just recently it has had troubles charging.
I have tried multiple USB cables and different charging sources, IE; Computer, Car, wall outlet. portable power, etc...
I seem to have the worst luck using the computer. Tried 2 different ones and different cables just to make sure.
It even seems to drain it a bit. When using a car charger or wall charger it appears to be hit or miss on whether or not it will take a charge or not. Any ideas on what should be next steps to try?

Some here have gotten juice down into the charging board causing the problem you describe. It's located inside the mod at the top where it is prone to get shorts from juice getting down in there from under the shuttle button. Disassemble the mod and clean everything up with contact cleaner. Disassembly is shown earlier in this thread.

 

[JeremyR]

4 torx and slide the board up to have a look. Dry out the juice with whatever you can qtip paper towel, the dip qtip in some alcohol to clean gard to reach spots, or use contact cleaner.

You could probably try to swab out the USB with alcohol without disassembling if you need to. Alcohol will rinse the juice away and dry quickly.

Mine today had issues charging .. none of my cables worked. I had a close look at the usb port on the VT60 .. there was bits of green oxidation on the pins!

I used my Swiss Army knives tweezers to scrape what I could, and used electronic contact cleaner (that alone did not get rid of the green oxidation). It's charging now, but I want to thoroughly clean it again with maybe a tiny metal bristle brush.

Just an FYI for those wishing to pick one up, either to try out TC or as a back-up.

VapeNW has the original Evic VT on Clearance now for $39.99, plus an additional 25% off with code: 25%offClearance

Collect them all

 

[atroph]

Code didn't seem to work.

 

[Joshatdot]

Yeah, 25%offClearance .. doesn't work for me either =\

 

[jefsview]

Sorry. I was just posting what's listed on their site. I had just bought my second one, so I wasn't going to order. If interested, perhaps you could email them and ask them to honor the posted sale, or to withdraw it.

 

[Joshatdot]

Yeah, I emailed them after the code didn't work. i hope they dont run out of VT60s

 

[jefsview]

It worked on the SVD kit next to it on the page -- you can get it for $13

Just wanted to say that I absolutely love this mod.
But it really needs to be bumped up to 75W.
Any chance we'll see a v2?

 

[atroph]

I doubt it. They missed the mark with no firmware upgrade-ability. Now that this thing is on clearance I don't really foresee a revival. IMO the internal battery turned people off. To me it was awesome with about 3 days between charges.

I'd like to be proven wrong though!!

Yes, it's called the Cuboid.
Other than that, I doubt it.

Meh... that's dual 18650.
I want the awesome lipo, small form-factor, beautiful paint, and at least 75w.
Too much to ask for?

 

[jefsview]

I don't think Joytech was comfortable with the lipo batteries, unlike Innokin. The also did a lot of polling and the vast majority of responders stated that they preferred replaceable batteries, hence why they abandoned the original Evic VT and pushed everything into the VTC Mini.

w00t! Vapemail from VapeNW. I got the VT60 in White & Black
