A question for VV owners from a truly lazy man.

[jwat82]

Here I am, haven't even gotten my grand yet (tomorrow yay!) and I'm already pondering a VV grand. Silly me.

So my question is this: is charging the batteries a pain? I understand that when you stack batteries they need to be charged carefully in pairs. Is that at all a hassle, or am I totally wrong about the charging part?

Thanks in advance!

First of all you need to mark the batteries. By set number then A or B. I always date mine too.

Use only in sets. Rotate which goes on top. The top battery will discharge faster.

Charging is not a problem for me. I use either my Pila with spacers or my X-tar for 18350's.

It is a pain for me to keep track of the top battery. I usually just meter them before I put them in. Putting the higher volt on top.

Yup, sounds like a pain in the rear. At least more of one than I'm looking for. I think I will hold off till I "mature" a bit, and just look at kicking my grand (already have the kick and the 500s) if I feel the need.

Thanks for the input!

I just keep my sets together and really pay no attention what goes on top or bottom. Just make sure I keep them together.

I own a VV Grand and have 3 sets of batteries for it. Each set is a pair, and each pair is part of a rotation.

Use one pair, pull them, charge them, then put them in their case.

In their case they sit until the cycle before them gets a turn. In essence, the set being used now will never be the set used fresh off the charger.

All batteries will have an idle discharge rate over time when unused. With each pair running on a 3ohm coil at 5v putting out a regulated 8.33 watts... Or this coil at about 1.2ohm @ 4v putting out a consistent 13.33w for an instant response and sub-ohm-like warm delicious vape...

Using a thin 30awg kanthal at 3ohm at 5v, the heat is instant, the vape is flawlessly predictable every time, and you are well within the discharge rate of a single 18350 (let alone stacked). But this is not limited to high resist. Like the one pictured... 1.2om, about 4v... It's like having a .6-.7ohm coil on an unregulated mod once it burns down into the sweet spot... All day long!

And if you are still concerned, the built in 15w limit will prevent you from firing if you are exceeding the limit, and the on/off switch will give you peace of mind not only to prevent misfire in your pocket, but also to limit the idle drain of the battery to that of the batteries natural chemistry without having a slow draw from the chip.

Hope that helps my friend!

If you need more power, you can also use 6v in the grand.

The button placement and feel on the VVG is my favorite part. Rocking 6-7 months with it and I don't mark any batteries or put dates on them or charge things together and all that jazz..

Just throw in 2 charged batteries and vape. When it gets weak, toss in another two. Everything karen 'n the rest of the folks suggested are good battery practices though. In 11 months (and many many batteries later) I only had 2 batteries die and I don't think any of them were 18350s either.

Then again, I never used a Grand before or any mechanical for that matter.

i'm kinda lazy too.

i label my battery pairs A0 & A1, B0& B1, and so on.

if i put a pair in on S-Tu-Th, the 0 goes on the bottom. Alternate days the 1 goes on the bottom

binary is about all the complexity my tiny brain can manage.

EDIT: on saturdays i go wild and crazy and just roll the dice...

 

[Wmmeese]

Mark the pairs with a manic marker A, B, C. Get some small sticky's and mark the top battery when you remove to charge so next time it goes on the bottom. Seems like it would work?

 

[jwat82]

I truly appreciate the insight!

It's gonna be a good while before my vape budget recovers from my grand, let alone allows me a VV. I'm sure many of you vastly underestimate the depths of my laziness, but the whole battery thing doesn't sound TOO terrible.

Thanks again!

In a regulated mod, stacking is little to no concern. It is when you get knuckleheads stacking batts in an unregulated mech, running super-low coils trying to create flavorless clouds that serve no purpose and overloading their batts... That is when the concern goes from "meh" to "get away from that idiot before he goes boom".

I've seen this kind of comment a bunch of times:

Use only in sets. Rotate which goes on top. The top battery will discharge faster.


This idea that you need to switch which battery is on top seems like complete voodoo to me, but many people keep repeating it.

From an electrical engineering point of view, this doesn't make any sense at all. I agree that you should keep batteries in pairs (if you use them 2 at a time) but which one is on top doesn't matter! They should both be doing the same amount of work regardless of which order you put them in! The ONLY reason I can think of to rotate them is if the top battery is getting heated up a lot from the heat generated by the atty, which really doesn't seem likely to me; if it was enough to make a difference to the battery, the PV would be uncomfortably hot to hold.

Can anyone point me to something explaining why the "swapping which battery is on top" makes any difference whatsoever? (Not an idiot, I have a BS in EE from MIT, back in the days when batteries were either lead-acid, carbon-zinc, or crystalline dilithium).

The electrons from the top battery run down in to the bottom battery, so it's like an hour glass thing.




LOL,,I keep em in sets but never worried about top and bottom.

 

[Treebeard]

I do keep mine in pairs... but I don't know why I do it. I've never given any thought as to putting one or the other on top and all that other stuff. I'll let ya'll know if I grow an extra limb or something as a result.


<--------glug, hehehe!

 

[Xobeloot]

I had never heard the top v. bottom thing prior to this thread. I just rotate pairs...

But Hey... If someone prefers top to bottom, who am I to judge?

 

[dodari]

Top--Bottom, Bottom--Top?

Maybe it has to do with egalitarianism? Whatever that means.

Isn't that the thing where people worship eggs?

i'm just a dumb self-taught engimaneer. i've gotten by on observation more than theory.

i swap em because the top battery consistently drains far lower than the bottom one.

i dunno. maybe my voltmeter is picking favorites...

Oh... the out of context satire dancing through my head reading this thread..... I need serious help

With my first two sets of 18350's in my VV Woodvil I did not take time to mark them. I used them in sets because that is how it worked with only 4.

I finally bought another VV and more batteries. Two batteries died. Would not charge. Read lower than 1v.

I bought some more batteries. Marked them. Began to pay attention by metering them when removing them. The top was always lower.

Since I have been careful to keep them in sets and try to always rotate top and bottom I have not lost a battery.

One other thing, I always pull them before they discharge below 3.5. I do not let them run until the VV REO shuts down.

All I can say is if you don't think it matters then fine. If you are concerned it might then meter your batteries and see what you find.
