As long as you just remember you only have a 7 amp limit your fine I was just making you aware of you were unsure. Only reason I know is because before I knew as much as I do now about batteries I abused one in my reo and I'm lucky I never had an issue. Just passing on some info. Have a good day.

Thanks. How do I find the amp rating on a given battery?

Li-ion Battery Test-Review-Specs: Panasonic NCR18650B 3400mah Amp Limit & 18650 Battery Datasheet

You can usually Google search the battery and find a spec sheet or someone who has tested the amp limit of the battery. Never go by what the manufacture says as many times these numbers are not accurate. A forum user, mooch does a lot of testing for the community and if you look up his name I'm sure you will find all of his tests which test the most popular batteries used by vapers.

I only use the green one with a mech mod. It won't even fit inside the pico. Here is a link where I ordered it:

https://www.fasttech.com/p/1345500
I would not use the Panasonic in a Mech mod if it was the last battery available. This is an unprotected battery and if you manage to get a coil short one day, you want to make sure there is a safe place to throw it... Immediately and without hesitation.

Pick up a pair of decent batteries for your Mech and ditch the Panasonic ones asap, it is not worth risking your safety for a few bucks.

so I could not believe when I got my silicone sleeve for the Pico (mail today)
I seen the sleeve and thought "what's that little thing for... ? "
was surprised it fit, it's so small... :eek:

mine are both showing the tarnishing - the sleeve made it all better :thumbs:

Wow !! I may just follow that advice. Didn't know it was that bad ...

Ask Mooch. Mooch is the king of batteries.

My black Pico is on charge right now with a brand new HG2 installed.
I like the shape, weight and feel of it. It will be a great finger fire mod. :thumb:
The HG2 is a 20 amp battery. It's what I use for vaping. The reason the pico specifies a 25 amp battery is because 75 watts / 3.1 cut off voltage = 25 amps. Amps draw increases as voltage drops. The cut off voltage is programed into the mod by the manufacturerer so that it's still safe to use at 75 watts at the lowest permitted voltage so long as that battery is rated for 25 amps. So if you're going to use a 20 amp battery safely you want to keep max watts at 60 so 60 watts / 3.1 voltage cutoff = 20 amps.

I never go above 30 watts so 30 watts / 3.1 volts = 10 amps. So if I run my mod at 30 watts until it stops firing I'm drawing 10 amps, half the 20 amp rating of the HG2. That's called head space. I like head space. If you are going to be responsible for choosing the batteries you use you should understand this math.

I don't really think I'll have a problem with my KF Undead or SQuape Rx on the Pico at 25W and even less with the GEM at 15W.

I don't think I'll put the Moonshot on the Pico with it's dual 22g 0.4Ω build though... :rolleyes:

But you could put the Moonshot on there if you didn't exceed 60W (or more like 56W, accounting for headroom). Whether or not that would be a satisfying vape is besides the point, which is that the resistance has no bearing in this particular safety equation. This is distinct from saying it doesn't matter period, but it does not factor into calculating the necessary continuous discharging rating to stay safe with a regulated device.

I don't know anyone who buys a single 18650 device and runs them at high wattage steady. An hour later you need another battery or a few hours to charge. :lol:

All of the VTC mini or iPV D2/D3 owners I know usually run around 40W, most are 30W or less so I don't see it any different for the WeeLeaf Pico people.

Indeed! And another reason for those that have not yet tried TEMP CONTROL. For my juices and Vape style, I find a setting of 35 watts to be perfect, I leave it there, and simply adjust my temps, even on my DNA200. 35 watts gets it going, then it quickly hits temp, especially on titanium coils, and you can watch if you like, the watts drop to less then half. I still however use both VTC 4's, and 5's.

@TrollDragon My previous post was not a suggestion of where to run your mod or what to put on it; I merely said you are capable of safely attaching any topper that will fire on the Pico using a 20A battery, regardless of its resistance, if you stay at or below 56W using the regulated mod amp draw formula. Whether or not that is prudent or economical for your battery life is a different discussion.

Granted, this advice was less at you and more for posterity, as I'm sure you've been here long enough to do your own math.

Contextually, to me it sounded like you did not want to put your Moonshot on the Pico because of amp draw, not battery drain. Did you mean the latter? If so, that was my mistake.

ed: Is there a way to check battery voltage on the Pico besides going into Bypass (which so far seems unreliable to me)? Because really my only point was that someone who doesn't understand amp draw from regulated mods should really learn why it would be unwise to use a 20A battery, set this mod at 75W, and vape until dead. You'd hope people wouldn't do that, but they will. I'm not at all insinuating that anyone here in particular doesn't understand what they're doing, just that it's especially important to be aware of the way regulated mods work when you only have one battery coupled with the ability ability to use high wattage.

Hey all, greetings from SE Asia. I've been Vaping for a while, but the Pico here is (strangely enough) my first regulated box mod, having subsisted on a beat up 18350 mech and a Taifun before this.

And dang, colour me impressed with how much Vaping tech has improved. I mean, a full 18650 battery and 75W in a box barely taller than my old setup (not that I ever need that much wattage anyway).

Sure, the buttons are loose, the paint scratches easily and the battery cover threads are crunchy, but as it stands I really like this little fella.

Diminutive Daily Driver by Eirakkun, on Flickr

Forgive the gaudy CF skin. Pics from this thread were showing alarming evidence of how much eLeaf paint tends to rub off, so I wrapped the Pico as soon as I was able (with whatever little skill I had).

The brushed metal areas aren't as lucky though. I don't really have "patina" developing on them, rather a whole lot of micro-scratches... especially at the bottom. The silicone cover could help... but I've never really been a fan on stretchy, sticky silly-cone.

Maybe I should just use re-purposed generic Invisible Shield to cover the brushed parts (like I have with the Pyrex of the GMv2 and the Pico screen). Or maybe it should just run with it and go with the "beat up daily driver" look most of my mods end up with anyway lol.

Really? If one allows time for the battery to "recover" from the last firing, I had thought that Bypass should be accurate... and easier than using the multi-click readout function.

Have you found it isn't?

I have just put an SS430 build in the SQRx to test out the Pico, using a TCR of 138 I get an excellent vape at 420F/35W. I tried the TC on the Pico not expecting too much, considering it comes from the same family the other Joyetech stuff does.

I was pleasantly surprised!

My only beef so far, is every RTA I put on it all seem to have their air hole line up with the battery cover... :glare:
