Atto mod

[defdock]

So what's up? Just ordered an atto mod that should be here on Monday.

Curious what other "atto users" got runnin, build wise and atty, on their setup?

Also, if it's a clone or original, maker if Known. Hear stories of chips set to regulate at 3.7 and some unregulated, also some that have short protection and some without.

 

[defdock]

Also curious about general responses to the overall personal "use" of the mod. Likes/dislikes, small things to take note of?

 

[rice721]

thats interesting, I had to look this one up, so its technically not a true mech mod since its got a board to regulate your voltage (constant 3.7V) and has failsafe to prevent thermal runaway should it happen?

 

[defdock]

The original supposedly has those features - yet I haven't seen anyone who actualy owns an authentic to discuss about the mod. The clone I received, does not seem exhibit those features, but I'm hoping it's due to a faulty chip... still testing, on day 2.

Discussion elsewhere notes that due to how the chip/mod is designed, there should be no possible way to add constant voltage regulation and/or other protections. I don't beleive it, but again I'm not an electronics expert either.

[rice721]

wish someone with the authentic would chime in on the board thats in this mod. Does it regulated the voltage? does it have a hard short protection? Its a really nice looking small piece of gear.

 

[defdock]

Not fully guaranteeing anything, but my clone seems to atleast exhibit low battery voltage cuttoff. Testing it the other day and it was cutting off at 2.9v(kinda low... but not horrible I guess). As far as voltage regulation, I don't think so, but my chip is damaged/bad qc so I dunno if that might be an issue either and the chip isn't fully functional. There was some discussion elsewhere on the website and how the chip can't physically have those features due to design, but I'm no expert, also how the chip "steals" like .2v or more in voltage drop compared to any other "standard" mech due to how it's designed.

Anywho, I just rebuilt the atty I was planning on keeping with it so it would work optimal in 350 with the extra voltage drop.

 

[rice721]

did u have to use batteries with a button top instead of flat with this thing?

 

[defdock]

The battery adjustment on the bottom accommodates for either battery type I beleive - it has a nipple contact on the plate. I'm using it currently with flat top batteries and have to screw the adjustment in a decent amount(assuming that extra space is for nipple top batties)

 

[defdock]

Please note, with this mod, the batteries get inserted positive side down

 

[rice721]

so you said you tested it and the mod seems to have a shut off at 2.9v? Does the hard short protection mean that this thing is generally safer than a regular mech?

I did some more research on this and it seems that since the battery is positive side down and the mod itself has a large enough vent hole at the bottom, that this thing shouldn't turn into a pipe bomb IF the battery goes haywire.

Yeah, since I've noticed it I've ben running my batteries till the cutoff. It seems it actualy cuts off at 3v, but continuing to "attempt" to fire the atomizer still drains the battery tho the chipset does not output the power to the atomizer.

Does the hard short protection mean that this thing is generally safer than a regular mech?

I don't wanna test it and find out
Il just assume yes, but stay precautious anyways.

This was the huge selling point for me, honestly. This was a really great design.

I think I'm going to purchase a clone after returning to Shanghai. Its about $20 shipped, should be the first mod I have thats as close to a mechanical. Sellers video said the chip protects from a hard short and reverse battery (which he tested out the latter).

I also like how the bottom adjustor acts like an on and off switch so you can just loosen it to prevent accidental firing when pocketing this thing. The mod itself is 22mm in diameter?

i have a FT clone atto. it's the one that came with the Pico RTA clone. it came without logos, which i prefer. i like it. i mostly run it in 18350 mode. not sure what power it's kicking out. but it runs my nectar micro clone, le magister clone, k.loud+G and pico clone pretty good. i run those at 15-20w on my regulated mods.

 

[defdock]

Yes, mod is 22mm

That "function" too sold me on it, just loosen the battery and throw it in my pocket.

Not sure which clone company your may end up being (I recall 3 different clone manufactures), but I hope you ended up with the sxk version like I did with all the "updates" on the chipboard vs the "original" chip.

there seems to be 1 thats incredibly popular on Taobao and its called "IN" clone. This "IN" if its a company also makes alot of other atty / mech mod clones. The sellers page also listed the chip as V3 and allows for a lowest build of 0.1ohm where as the previous v2 was 0.2ohm (never gonna go that low, even on a regulated).

I'll prob pair this with my serpent mini and build around 0.8 or even 1.2.

i have a FT clone atto.

Did that one come installed with the sxk chip?
That was the atto I initially ordered, but canceled and got one local. Still have replacement chips being sent tho

I am too happy to hear this.

I only thought there was a v2(v1.01)

Glad the chipset is still being looked at for further development. Might have to sorce me one of the new chips too

Just ordered it. Got the "in" version instead of the sxk one. Saw a different finish for the sxk clone but it was asking $50.

I'm going to assume that the short protection is to protect firing on an atty short and has nothing to do with a hard short battery protection?

That would make more logical sence. I don't understand how a chip would protect from a hard battery short (torn wrap)

Lemme know how ya like it, when ya receive yours


I got one of my replacement chips today in the mail. Same "rugged" edges (not fully sanded) like the chip that came with my mod but the rest of the module looks in better shape. It seems/feels to be outputting slightly more voltage than the previous, guessing due to better solder job. Still testing for battery cuttoff though
