Can somebody please calm my fears?!

[KalebK]

Ok so im almost ready to take the plunge and purchase the EVO VV (its beautiful!) but I have some questions before I place my order!

1. This unit takes stacked batteries, but I heard this was a no-no and I would rather not blow my face off or start a fire!! Are the batteries that come with it sufficient (I don't think they are protected)?
2. Is the charger that comes with the kit a good one or should I purchase another?
3. Which vendor should I go with?

I am trying to decide if it would be better to not get the kit an just order the device, batteries and charger seperately? Thanks so much!!

 

[Ratchet]

Which vendor are you getting this from? Never seen that unit and I have no idea what the cost of these is but I'm not sure about stacking batteries... I heard, just like you did, it's not a good idea. I am using a Lavatube that I'm absolutely loving. Lots of batteries are unprotected, the LT will only take unprotected batteries, the protected ones are slightly longer and won't fit too good, I think. But they are not stacked, only one battery...

If you're buying it from here 310Vapers.com | "3VO" EVO v2.1 Variable Voltage Mod - Featured Products | e-Cigarette, eGo, 3VO, cartomizers, atomizers, batteries it looks ok by ECF standards( yes this website does standards for acceptable PVs) . The saving grace is it's vented so much safer than non vented. Venting allows the gas to escape without building pressure up.
Always keep the batteries as a pair and label them as such. And if you can, switch the loading every time you charge them. IE, 1 battery on top this time, the other on top the next time in the stack.

Edit: from a safety standpoint I personally never stack batts just as I don't leave my batts charging unattended.

Always always always use protected batteries if you're going to stack (best case scenario, you should use protected batteries in any PV, but we live in the real world). Yes it's a cautious step, and chances of something going wrong are low, but it's not worth the risk. Protected batteries are not that much more expensive (or anymore expensive depending on the vendor). However, stacking batteries in a device specially designed for stacking is not necessarily dangerous. You have to be cautious; be extremely careful to use the correct batteries, not only protected wise, but also output wise. And make absolutely sure that the case is vented. I also would not recommend storing the batteries in the device for long periods of time, and inspect them regularly to make sure they are undamaged. With a bit of upkeep and caution, stacked devices aren't necessarily dangerous.

I think the problems arise when two stacked batteries have different charges which puts too much stress on on of the batteries, thus the need to keep them matched. Switching them helps keep them conditioned.

There are VV mods that use one battery.

Vapoor, do you mean interchange them in the unit or on the charger? Or both?

 

[Vapoor eyes er]

In the Unit/ PV. The trick, as mooreted explained, is to keep 2 batts with the exact same charge together all the time. Some even recomend testing the batts every so often. Unless you're a really heavy smoker the single battery/ 3.7 would prolly suffice. I smoked VERY strong analogs ( people would rather go without then have one of mine) and tried a higher voltage and it was too much.

Thanks for the response, I think I may wait for the eGo-C Twist.

 

[Vapoor eyes er]

You're welcome. You mean this one?

 

[KalebK]

Yes, it looks awesome!!! I really like the EVO too though so im not sure which one ill get yet. Ive never heard of eGo's being unsafe, but I have heard of mods being unsafe. I watched a video that said you cant hook up an EVO to a meter either, so im still alittle nervous about it.

 

[elfstone]

You can hook it up to a meter. But it will not register the voltage, because it uses something called pulse width modulation. Think of it as the mod turning on and off really-really fast. To achieve a warmer vape (i.e. higher voltage) it spends more time On, and less Off.

It is not considered necessarily unsafe - it has a venting hole, but it's kind of small. It has a feature to 'blow up' in a controlled way so as not to really explode and, finally, it has some electronic protections.

This is one of the most reasonable reviews of this. There was a huge rattle about this mod because of issues unrelated to its performance, but...

It also links to the SVR, basically the same thing minus the differences described in the first video where you can learn more about it.

The EVO has gotten some very good reviews. Just use protected batteries and you will be fine. Thousands of us (probably hundreds of thousands) have been using stacked batteries for several years with no issues. When you look at the statistics, I would not be too worried. Plus as mentioned, I believe the EVO is vented.

this thread was a great help to me as I was also looking at those as options for my first mod along with the LavaTube still not sure what I am gonna get but any and all information on the topic would be appreciated

 

[KalebK]

I spoke with a gentleman from 310Vapers today (who was very nice btw) and he told me that the AW IMR 16340 550 mAH batteries were better vs. The AW ICR 123 16340 750 mAH batteries that are protected. Is this right?

 

[newq]

That would be correct. The IMR have a better C rating for High Drain applications. I owned a EVO from 310vapers. I dropped it 4 ft to the concrete and broke it IMO the device is nice so long as you care for it properly.

Somethings to know about the EvO

It works well with a host of cartos. It is very good with battery life and does what it says when it should. My only gripes aboutthe unit were that thethreading was thin on the devices and after 3 weeks of pocketing the devices and rough handling it the cap thread stripped (they are thin IMO and only 3 of the 6 threads actually grabbed in the first place). The second gripe I have is that when I dropped the unit from a 4 ft drop to pavement , the unit fell bottom down and when it did I am assuming the batteries sprung up and smacked the electronics and then all it would do was flas a little red circle at me. , a shame considering i loved that mod. It was sleek sexy and a good power house for its modest size. I only wish my job wasnt so rough on everything. I have yet to find a mod that will withstand my job.

 

[KalebK]

Sad, its on sale and cheaper from thehouseofvapor.com but they dont offer the IMR batteries, just the ICR. Id rather spend more money to stay safe though!!!

 

[Vapoor eyes er]

I have, although different mah from the ones you illustrated, 2 different brands of batts. With the inferior Trustfires, at 50% discharge, performance falls off a cliff whereas the IMR batts perform strongly from start to finish. This was confirmed in the Flashlight Forum...yes there is a flashlight forum and they test many batts there. Whenever possible I've always encouraged people to purchase the higher quality batts as they will pay off in the long run.

I would not go with the lavatube due to it's limitations on what carto or atty you can use with it. You cannot use 1.5/1.7 ohm dual coil cartos, for example, on the lavatube. Other VV's, including the selectable EVO does not have those limitations.

 

[tica02]

That ego c twist looks fantastic. I may go for that next, I wonder when it comes out!

 

[drunkensatyr]

+ 1 for Lava Tubes here. Been using one for a little over a month and I only wish I had had one of these the 1st time I dabbled in PV's. As for the issue raised over low rez carts, I have never found that I "need" one to provide enough vap to be happy. Running a standard dual coil 4mg tank with self oversized feed opening. Took 30 secconds with a drywall screw to open it up enough to allow my 50/50 PG/VG juices to flow evenly.

I use it about once an hour for 7-10 min and find that I can easily go 1.5 - 2 days on a single charge.

Side note, Love the VV so I can dial down the power when I drip and then dial it right back up for tanks.
