    Why are you still hanging out in the Radius forum? 20 guesses would get me 20 trips to the sin bin...

    Official ProVari Radius Thread - Part 2

    I guess the wattage wars are alive and well, and everyone has to have a 200W mod. P4You have just announced the IPV5 - another 200W mod running on dual 18650's. Man, we're gonna see some fireworks this year! :facepalm: :danger:

    No, that's not entirely correct. The pulse rating on batteries is very misunderstood. Every manufacturer has a different idea of what "pulse" means. What's the duration of the pulse, and how often over what time period? Heat is additive, and the more current you draw, regardless of the time...

    That would have been a fair statement had YiHi not already stated multiple times in multiple places, their own math showing >30A draw, and "make sure you use a 35A battery" - I guess nobody let them know those don't exist, or they saw a photo of a "35A" Efest.

    It's simple math. To maintain any given wattage on a regulated mod, you must pull a certain amount of current from the battery based on its voltage. As voltage decreases, current increases. So, the lower you let the voltage get in your battery, the more current you need to pull to maintain...

    There is no 35A 18650 on the market. They keep mentioning resistance, which is irrelevant. Their current calculations are for the atomizer, not the battery. They really have no idea what they're doing!

    SXmini Q Class Powered by YiHi SX450 chip

    Not only do you need to consider the cutoff voltage, but beyond the cutoff voltage. Attempting to draw 33A from an 18650 would result in a HUGE voltage drop. As we know from other YiHi chips, the battery cutoff voltage may be 3.3V, but if you have 3.31V left, it will fire, and there will be...

    News flash: YiHi have just announced their next mod. What's that have to do with ProVape? Well, ProVape have limited the Radius to 40W on a single 18650. YiHi originally released the SXmini at 60W, then foolishly bumped it up to 75W with a firmware update. The DNA200 requires 3x 18650's to...

    That depends on what you're trying to achieve, and how close you're riding to that temperature. Are you trying to avoid burnt hits? Are you trying to avoid the production of dangerous chemicals at the base chemical thermal limit? Are you willing to stay ~40F under that limit just to be safe...

    The reason nobody has done it yet is because the change in resistance when heated is very minimal. It's hard enough to read resistances to the thousandth of an ohm accurately, let alone narrow your margin/scale, and get an accurate result. The further you go away from Ni200, the more...

    Well, he's kinda right... You can think of these coils as resistors in a circuit, just as you can think of your stereo speakers as resistors in a circuit. Wire has resistance, as we all know. Heat the wire, and the resistance changes. Ni200 was originally chosen because it has the largest...

    SXmini Q Class Powered by YiHi SX450 chip

    Prediction: People are going to be venting batteries faster than we've ever seen before. Nice looking mod - just not sure about YiHi's choice of allowing it to reach 200W on only 2x 18650's. The DNA200 requires 3x 18650's for good reason, and limits power to 133W with 2x 18650's.

    The YiHi SX350 35W Chip at Varitube

    What are the differences in the firmware between the ML-class and the V2 modder's board? Do you foresee any issues upgrading an M-class to the V2 board? Thanks Perry! PS - For the 0.5mm difference in screen depth, why not put a clear or colored piece of mylar inbetween to make up the...

    I wonder what ProVape's next mod/product will be? Yeah, about 2 years early to be guessing, but why not have some fun now. There was a major trend away from tube mods to box mods, and ProVape eventually followed suit with the Radius. They even doubled the wattage on the P3 to 40W on the...

    SXmini M Class (TEMP CONTROL)

    Like a dual 18650 mod? :) Hopefully with more than a 500mA charger. Even ProVape has an 800mA charger on the Radius, leaving pretty much everyone else in the dust.

    He melted it because he used more than the recommended 20W. They didn't recommend an amp rating, because it's totally meaningless. People assume that lower resistance and higher amperage equals more heat - it doesn't. 20W of heat is 20W of heat, regardless of the resistance of the coil, or...

    I just don't get that logic. If you vape at 11W, what difference does it make what the mod is capable of, when both are delivering deadly accuracy so the experience is exactly the same? What kind of car do you drive, and how fast do you drive it? Chances are it's capable of at least 100MPH...
