Am i stupid or this batteries connected in series ( positive to negative ) ? that mean doubling the voltage while maintaining the same capacity rating..... ( 8.4v 1600 mah ) If so , they using simple VRM -- ONLY can do downboost , not regulated probably.....
I can be wrong about series -- can't see picture clearly -- could be in parallel ( positive to positive , negative to negative ) just as well -- doubling the capacity (amp hours) of the battery while maintaining the voltage (3.7v, 3200 mah)



Did u check it with multimeter ? If they in series -- they will drop voltage as soon as batteries drains.....And it is very important to make sure both stacking batteries charged at same level ....

He made two versions 18650.
One is boost and the other is regulated.

http://ukvapers.com/topic/14056-pimped-vv-papa-mods-on-there-way/

Think i read before they are in series, stand to be corrected on that, maybe one is and the other is'nt

Have'nt a clue about mods tbh, think i will stick to eGo batteries !

alec76

i've got it now .... this one in series papa -r, what he calls regulated ....low capacity, double voltage at the start (8.4)....
another one PAPA -B -- in parallel, double capacity can do UPBOOST ....
not sure if it is better than lavatube electronic wise ...

What is this boost?

Regulated device tries to keep same voltage and boost .........?

alec76

Regulated device tries to keep same voltage

er.... u see two batteries in series got double voltage at the start 4.2+4.2 =8.4
if u' set papa-r to 6 v for instance, this thing theoretically could work till they drains to 3+3=6
papa-b "boost" - works probably on same principle as LAVATUBE -- can boost voltage from 3.7 up to to 5-6 volts
i think papa-b is potentially safest device to use IMO

It's series with a step down switching regulator - this is the best way to go according to CraigHB at the ECF;

Best setup is series batts with a step-down switching regulator. The exception is if you really want to add USB charging. Then boost is better since a single cell makes USB charging easy to do.

From Stig at UKVapers;

Performance wise and battery life is about the same depending how the user uses them. With the boost one it can be run on just one battery (with a little performance hit ie with duel coils) but can sustain higher voltage as the batteries deplete also the output voltage can be increased more (I've just done one for someone who like to run duel coils & will run upto 5.5v under load as well as HV atty at 8.0+v so the voltage range was 3.6 to 8.4 volts to suits his vaping style).
The regulated one will go a little higher with duel coil attys but as the battery's run almost flat there will be a slight voltage drop (but you should charge before they go that low anyway).
Hard to recomend one over the other as I like them both and use both.

series (stacking batteries) are potentially more dangerous set up..

surely , to charge 2 cell in series via usb u need balancing charger -- to make sure each of them charges equally

Not with protected batteries, even IMR's as long as you're not pushing the mod too far with LR devices.

After vaping since about 9.30am on this mod my batteries are down from 4.1 to 4 volts.
This was using it fairly frequently at 4.5 volts with a 3ohm carto.

mrplop

12.55 today - same batteries working perfectly in the mod.

They're down to 3.8 volts and still giving me a bigger hit at 4.5volts than the Lavatube does...

No explosions yet either.

*Thursday morning;

Switched the batteries out even though they were still working because I didn't want the charge to drop too low, the batteries both read 3.5 on the multimeter - after two days of frequent vaping.

Sir Digby Chicken Caesar

few threads on ukvapers about that brand, seem to be ok
*shrug*

i only know enough about batteries to know that I should be scared of them my aw imr high drain's may be unneccesary brand-whoring according to some, but until i know better they're just what im going to stick with as I can be reasonably sure they come reccomended.

They seem to tick all the right boxes except one.
They may be too long for the lavatube, at 68.5mm you may not get the end cap on.

mrplop

Those Senybors are a good purchase - they are basically protected high drains plus the mah rating isn't a lie. They're also one of the only 2c batteries that will fit in a TR-001 charger but only just.

Sir Digby Chicken Caesar

wait, the aw imrs are only 1600 mah
lol, jesus
that's some jump in life
half tempted to get some myself now

Over on another forum (forum slut that I am) I seen whare thoes batteries, the Senybors, are a bit long and the cap dosn't close fully. this fills the gap;

what 2c has to do with the size btw ?
C= capacity ie 2400mAh
2C= 2400^2 i.e 4800 mah ( 4.8 A ) discharge rate

I don't think he was saying 2c had anything to do with the size.

Protected 18650's can be 70mm long - this battery happens to be 68.5mm's long - it also happens to be 2C. If you bought the 2800mah version of this battery from this seller(which is also 2C) it wouldn't fit in a TR-001 charger (the charger that everyone with a Lavatube owns) because it's 69.66mm's long.

This is the only protected 2C battery (that this vendor sells) that will fit in a TR-001 charger.

The 2C (double the discharge) rating has nothing to do with battery size, battery protection in conjunction with capacity does.

Do you think that you have to spend €300 on a mod before you're qualified to talk about this stuff?:rolleyes:

Sir Digby Chicken Caesar

wait
so even though the battery is 2400mah.. it's 4800mah?

so is it almost twice as good as an aw imr 18650 or is it almost 4 times as good in terms of battery life

nope , you are confusing capacity and max. discharge rate

aw imr 18650 is rated 10C or so ... i.e. could provide up to 16A , low capacity, but it can supply very high currents

They look like the standard batteries which come with all Lavatubes. They are fine as long as you look after them

I ordered the lavatube in the end from liberty flights along with the charger and 10 x BOGE 510 CARTOMIZER 2.0 OHM (STEEL)

I would appreciate a bit of advice on the batteries.... I have ordered 2 of the following... http://www.irishvapers.ie/clearance/152-aw-1600-mah-protected-18650-batteries.html Are they sufficient for the lavatube to work properly?

http://www.irishvapers.ie/clearance/137-protected-smoktech-2200-mah-battery.html Do these smoktech batteries fit the lavatube and if yes are they better than the IMR ones above?

And is there a drip-tip or a tank needed to work with the boge 510 cartomisers and if yes what would be recommended?

Those batteries from irishvapers.ie are perfect for you lavatube.
Any standard 510 drip tip will do for those cartos .

Are the smok batteries ok as well? I just want to be sure before I order one because I'm thinking they might last longer between charges than the other ones due to being 2200mah

They may be too long. I don't expect them to last as long as the imr batteries even though they have a higher mah rating.
Stick with the imr batteries, great value at that price.

I don't think they're the same batteries mate.

I'd stick with the IMR's in the Lavatube, the 2.5amp limitation and the built in protection will make them pretty safe to use. I just bought a couple for my mod and when they arrive I'll try them out in the Lavatube to see how they perform.

Sir Digby Chicken Caesar

cool, ill keep refreshing the thread till then

one of th benefits of the imrs is they keep their performance at a relatively similar level as ther voltage drops too isnt it? I wonder if protection li-ions would be the same.
it might last longer before needing a charge, but would the performance be equivelant

mrplop

The IMR's are better with boost mods because of their consistant and high discharge rate especially mods that are higher ampage, at the same time a protected battery with a rating high enough to handle higher amp draw would be okay with the Lavatube also.

The 2C Senybors can deliver enough ampage for the L/T with it's 2.5 amp limit

If you were using a battery which didn't have a high enough discharge rate and your mod was trying to draw too much ampage then you'd end up with an overstressed battery - this could cause bad things to happen.

These ARE the batteries that came with the first production run of the Lavatube - they originally had fake AW stickers on them.

I have a couple and they're grand, not heard of any people blowing their faces off with them and they last quite a good while - some folks say they're Sanyo batteries but I doubt that's true.

They work very nicely in the L/T...

I DUNNO about senybor batteries , never had one , i would like to see discharge curves at 3-4A though, discharge at 1A - useless for us.....
speaking about 2.5A limits, keep in mind -- that's output , actual draw from battery could up to 4amps easy .( seen few tests on provari, lads measuring currents before booster and after )
If u looking for good performance battery at decent price -- Sanyo 2600 one of the best ,well , if they not fake ones , not protected though

discharge curves to 3v at 3amps
imr 1600



discharged in 30 min

Sanyo 2600mAh



discharged in 48 min


what u have to compare is
voltage (V) and power (W) curves, especially power drops .....

mrplop

Alec,

Is that extra draw specific to mods with booster circuitry?

alec76

yes , and i also believe it is specific to the law of conservation energy
Unless someone could invent perpetual motion devices
For instance
2.5A - OUTPUT
4V- OUTPUT
3.7v - input (battery voltage)

2.5* (4/3.7)= 2.7A input

or
2.5A -output
5.5 v -output
3.5 v -input
2.5*(5.5/3.5)=3.93A input

mrplop

Thanks mate.
Is there a calculator out there for this?

Hunter Mahan

The senybor batteries work perfectly and hold their charge / performance longer than the batteries originally supplied.

They are a couple of mil's, 2 probably, too big, but the base still screws in most of the way. I went to my my local motor factor's and picked up an O ring for .30c just to hide the little bit of thread which was exposed.

Sir Digby Chicken Caesar

how much longer, roughly?
tempted to pull the trigger on 2 of them as im running through two of the ones I have in one day atm

Hunter Mahan

2.4 millimeters longer by the looks of it.

I think Sir Digby meant longer lasting rather than longer length. It seems he's sucking down 4400 mAh a day with his lava tube.

Sir Digby Chicken Caesar

well, no
the aw's i ahve are 1600, they come out of the charger at 4.1v and i recharge at 3.6v so I guess im going through roughhly 1600mah a day

Hunter Mahan

I have to admit that the Lavatube is by far the best piece of kit I've tried.

In order for me:
1 - Lavatube with arry tank v3 and clearomizers
2 - Screwdriver with basically anything on it
3 - Ego T

I have recently received the arry tank v4 in stainless steel and it looks and feels the business. I've not tried it yet as I am waiting for some boge carts to arrive.

The lavatube with the arry tank and clearo's inside is fantastic for vapour and flavour, and I have never, not once, experienced a leak with it. Which as most vapers will attest is the most annoying feature of some systems.

The only reason I've jumped to the new version arry tank is because his products are usually hard to source after a short period of time and I like the idea of the screw on cap and the seals on it.

I usually vape anywhere between 4.4 and 5 and that suits me perfectly. My main flavour is RY4 and I am down to 1% nicotine level which is around 9/10 mg's I think. I dropped down to that level last week and despite reports I have found no drop in throat hit or any increase in vaping. I hope to level off at 0.6% by the end of April and stay at that level.

I'm determined my only costs going forward will be cartomizers and liquid, even then I am going to reduce the cost of the liquid by making my own batch of RY4.

Sir Digby Chicken Caesar

is arry still selling arry tanks?
might grab one..

Hunter Mahan

Going back to the batteries, I went through roughly 1 and a half batteries a day with the ones originally supplied, and the ones I bought last the whole day just about.

Not very technical I know but that's as good as you'll get from me

Sir Digby Chicken Caesar

seems good enough seeing as how we vape at roughly the same voltages and use similar enough battery life

id love to get one of those multimeters pbusardo has where he just screws it into the 510 thread on the device and it reads exactly how much the charge is on a battery and under load
be so easy to figure out what batteries to use then

He's selling the food grade stainless steel ones, V3 is no longer in production as far as I know. I had to buy my V3 from Stormy in America and all they had was one.

Sir Digby Chicken Caesar

ah well it's the SS ones I'd want, i have yet to have a good experience with clearomisers although im hoping the vision stardust winging its way to me from china will change that

Hunter Mahan

Where did you buy your lavatube from? I got mine from Liberty and I had to buy the batteries separately.
I bought some spare batteries from an Irish website and the batteries were different, had the flat head, but were just slightly different at the positive flat end. Cosmetic I thought, but they were terrible only lasted half a day at max.

If you are interested I'll post pics when I get a chance showing the difference.

Sir Digby Chicken Caesar

i got mine from irishvapers in december, had to get other batteries too as every supplier got shafted with knockoff chinese batteries with the first order so I just ordered some aw imr's online.

so bloody hard to know with batteries
