SXmini Q Class Powered by YiHi SX450 chip
Yeah, but don't worry, eventually the Evolv fanboys get tired of making stuff up. ;) -
SXmini Q Class Powered by YiHi SX450 chip
The lack of a menu setting to change the preheat on the DNA-200 is my biggest pet peeve about that chip. It was utterly useless to me when I first got it. Only after I spent hours figuring out how to run escribe via virtualbox could I get the mod to actually be useful. As such, I would never... -
SXmini Q Class Powered by YiHi SX450 chip
Voltage step-down converters are typically more efficient than voltage step-up converters, thus using a serial configuration gives you slightly more efficient battery usage over the full range of output voltages. -
SXmini Q Class Powered by YiHi SX450 chip
So the IPV5 also just got announced, which appears to be the Q-class's cheaper cousin using the SX330-200 chip: IPV5 Box Mod 200w $50.34 | Vaping Cheap -

That's correct. The main underlying issue is heat generated by the current within the battery. If you're pulling a constant current, then the CDR is the limit at which a sustained current draw won't overheat the battery. If you're doing pulsed current draw, then you can pull more current so long... -
SXmini Q Class Powered by YiHi SX450 chip
The chip design determines the load on the battery, thus controlling the current draw. It then converts the power obtained from the battery to the appropriate power to be delivered to the atomizer. If the system is not designed to handle the current draw, such as with the DNA40, then it cannot... -
SXmini Q Class Powered by YiHi SX450 chip
Well, it's not so much a rhetorical question, as a statement built on false assumptions. A mod is not just its batteries, but also the wiring and the chip too. Those also have to be designed to handle the current draw at issue, which the SXM was not designed to do. It's no different than the DNA... -
SXmini Q Class Powered by YiHi SX450 chip
So far as evaluating whether the product can perform what it claims, we only need to concern ourself with a charged battery and how it performs. So far as when the battery is below maximum charge, we don't know anything about how the product performs. For example, it may limit the maximum... -
*GEM: A new RTA by MarkBugs
Yep, various methods of precision temperature control in heating elements are well known. The only issue is coming up with a cheap, reliable and compact application of those methods for vaping, which I'd say is mostly about having the money for building machines to mass product such a product... -

When one looks at battery test charts, they don't even remotely support your claims that your arbitrarily-defined cutoff voltage is the right measurement. After that, you're just piling on nonsense. -
SXmini Q Class Powered by YiHi SX450 chip
Evolv supports the use of 18650s with the DNA 200, as shown by their own comments and the addition of the 133W mode to support dual 18650 configurations. As to the issue of safe battery enclosures, Evolv only specifies the electrical requirements of the battery. They don't provide information... -
SXmini Q Class Powered by YiHi SX450 chip
I've seen enough poorly design LiPo enclosures on DNA 200 mods to say that I don't think Evolv exactly went for safety. Rather they just foisted liability on someone else. At least 18650s have built-in impact and fire resistance, whereas modders often seem to just cram in the largest LiPo they... -
SXmini Q Class Powered by YiHi SX450 chip
Nope. First off, the cutoff voltage you cite isn't based on the battery spec (which is typically around 2.5V). Rather it's a voltage used in the vaping industry to maintain battery life, which has nothing to do with how the batteries perform under load. Second, the nominal voltage given by the... -
SXmini Q Class Powered by YiHi SX450 chip
Typically industry calculation is to use around 3.7V, not the cutoff voltage. Also, the CDR is only for constant discharge. Batteries can safely support higher discharge rates for short periods of time without being unsafe. -
SXmini Q Class Powered by YiHi SX450 chip
Sort of agree with you, in that the chip can handle a lot of safety issues. Even more if it has a temperature sensor on the batteries. However, that doesn't fix the most common reason I've seen for people being injured by mods, which is that they aren't designed to vent properly if the battery... -
SXmini Q Class Powered by YiHi SX450 chip
Not really, the VTC4 has a cdr of 30A, so that can give about 222 Watts with a dual battery config. Further, we're not using the battery in constant discharge, but more of a pulse configuration. Given that the VTC4 can support a pulse discharge of 60A for under 30s, it likely can handle it even... -

And here I thought Evolv just copied everything from Diocodes. ;p -
SXmini Q Class Powered by YiHi SX450 chip
Probably a 200W preheat, followed by a lower setting. More than enough for any TC user. The real question from me is if the software is as meh as escribe. I don't want to use a USB-tethered 90s-style user interface to configure my mod. -
SXmini M Class (TEMP CONTROL)
I'm not a fan of USB charging, but dual 18650 would be nice. Only problem with dual 18650s is that I have to keep even more batteries charged. ;) Mostly, what I am hoping for is something that I can configure for my phone. The software so far from Evolv and Yihi is pretty meh.
