I've got a couple MNKE IMRs right now. I like the capacity, but I don't like the idea of chain vaping them at 30a.

It might depend on how low you're planning on building. My MNKE IMRs are not phased by my .3 ohm quad coil build on the mech...
I have the Keeppower 50a's and like them very well, they do last longer than the orange mnkes.
Did you use the delrin spacers at top and bottom?
Did you move the ground wire to reverse protection?
Is the battery pin shorting out?
Board is spec'd for max voltage of 9.5v and given a 2 ohm coil... That works out to 45watts...
To get to 50watts, with a 2 ohm coil, you would have to do 10volts and 5amps... Maybe the chipset can't dc to dc convert that ???
The 350 is indeed limited to 9.5V on upconvert, however it will not flash the screen show battery problem funky crap like that. It will simply show 50W and never get there. Phil Busardo has an excellent review of the 350 on his website.
I feel I should also mention, this chip is meant for subohming. That's what the focus was in designing it. And that comes from YiHi, it's not just some random crap I'm spouting off.

Just from your experience, do you think they're really good up to 50a? I get nervous using low builds on mine as a mech, because the ratings for the MNKEs are anywhere from 10a-35a. There's a build I really want to try, but it'll draw 48a based on Ohm's Law. Definitely don't want to risk that on an MNKE.

If you're nervous...calculate your amp draw and tay within the limits. It's pretty simple...
I want to increase my safe amp draw, that's why I'm looking at upgrading my batteries.

Just under .09, for 200w. I'd probably only use that build for 15 minutes before going back up to my comfort zone, but I just really want to try it.

The "50A" Keeppower batteries show a continuous rating of 13A, and have been tested to a much lower rating. 20A is a more realistic and safe discharge rate for this one.
Same with the old Sonys...the 50A is a maximum pulse discharge rate, in which case the MNKEs still have it beat with 60A max pulse discharge rate. That being said, I haven't even gotten close to drawing over 20A...The super low builds might be better suited to the more modern 18650s.

Screw it, I'll just stick with the MNKEs. With that much power, I'll only be drawing for around 5 seconds anyway, which ought to be within the pulse range. Skeevy advertising and misinformation don't really give me much faith for any battery, now that I think about it. Or I'll just wait until I rip the chip out of my 18650 350 mod, and convert it to mech so I can use the VTC5.

These new VAPPOWER IMR 26650 specs look good, 40A continuous/60 pulse at 4200mah. I'd like to see them tested though.
I was looking at them too. Just based on the name, I've already got a potential catchphrase in my head: "Designed by vapers, for vapers." They're definitely tempting.

A New Kind of Battery Test for Vaping
Good charts here. Even at a .2 ohm build...the 26650s have a quite a bit of voltage sag. I will have to take this into consideration when calculating the amp draw on my builds. .2 ohm on the MNKE shows a voltage sag to about 3.35V...meaning it's only really drawing 16.75A @ 56.11W.
The build I have on the mech right now (.3 ohm) is only drawing approx 11.17A and 37.41W...a little more than half of the continuous rating anyway. Lower ohm builds have more voltage sag, so even a .17 ohm build will pull less than 20A.
Interesting. I need to invest in a nice inline volt meter so I can test voltage draws under load.

Hmm. I wonder just how much trouble it would be to design a calculator that factors that information in, based on whatever battery you're using. It's definitely enlightening. Looks like those KP Private Label are the way to go as far as voltage sag and lasting power.

I have a pair ... I don't have much test equipment/etc. But they seem to last longer than the MNKE, and they sure drop a lot less on my battery meter on the Seven-30 when I fire it...
I believe that's due to the increased capacity., but I'm definitely no electrician, so I could be wrong.

Only question is...where to actually get these "Kidney Puncher" Private Label batteries...I don't see 'em listed on their site.
According to the chart...they drop a tad less during their tests...3.44V vs the MNKE's 3.34 or so. The KP Private Labels drop to 3.5-6 or so. The 18650s fare a bit better...and might be better for extreme sub-ohm builds...but drop off much faster. I'm been generally happy with my quad .3 ohm build in my 30mm Tobh as it is.
People have built to .09 on 26650 MNKEs safely, and "daily" .18-.2. I might try .18-.2 myself (still won't even hit 20A at that ohm), but I don't personally feel a need to dip much lower.
