So I'll be using my Koopor Primus, which is great-a triple 18650-and I'm okay with it until it breaks since it works well, but I have a safety concern. If I put 3 LG HB6 (pink) 18650's, and use a Horizon Arctic V12 .1ohm 12xClapton coil at 220W or possible higher, Ohm's law states that 30amps...even at 4.2V per each battery in series, isn't enough for that kinda vaping. The calc says 43.4 amps or something similar. If the youtube testers and people who recommended it to me haven't had issues (and those people likely didn't use LG HB6's because many don't know it's the most powerful cell for the short 1500mAH it has, but...) would I be okay? I'll probably prefer the .3ohm coil which is the other clapton option but still it's about 190-200W. I don't think triple batteries helps with this issue only perhaps a tiny bit longer battery time? I'm worried because I'm sticking to the Cleito 120 and Arctic V8 Dual Klapton (V2-series of coils) which is .2ohms but not to be used at wattages higher than 140W. I eventually want to get this Arctic V12 since I love the brand and that line of products (arctic). I cloud chase without nicotine these days because I can't help but crave a small corona Rocky Patel cigar a few times daily as well and I chain vape while I'm busy indoors so this is a hobby that became serious part of my life as of this month and I wanna be safe. Help? I use the Sigelei J150 2-cell Lipo 2000mAH 35amp beast of a small thing but it's not gonna cut it since it's definitely a 150W 35amp vaporizer but I just don't wanna be trapped and not move on to the cloud chaser's new generation. Thanks in advance.
The LG HB6 is the strongest battery on the market and coolest running battery at high amp load, nothing out does its 30amp Continuous Discharge of 30 amps, anything above that is actually a short pulse discharge rating which can be dangerous, you don't know if the pulse 1/2 second or 3 seconds, nor the rest time to recover to do that pulse again under passive cooling conditions, ambient air, which we use, if they are liquid, cryo, or a cooling fan active cooling would be a different issue then. Regulated mods use a different formula of Ohm's Law using watts/lowest battery level before shutoff. Remember that regulated mods when voltage needed is above what is being supplied, pull extra amps from the battery, direct it through a "Boost" circuit that converts them to volts and sends the boost into the actual voltage signal to the coils. This gets more and more seen as the voltage of the batteries lowers, so higher amps are pulled the closer to battery shutoff you get, completely opposite of a Mechanical where the highest amps are pulled at fresh battery charge.
Most regulated mods the cutoff voltage for each battery is at a range of 3.0 to 3.6v depending upon how it is programmed, and on average at 3.0v cutoff the wattage ranges for batteries fall as so, 60watts/3v=20amps, 75watts/3v=25amps, 90watts/3v=30amps (your LG HB6's woudl be 90watts per cell safely at 3v).
These super fancy high powered mods like the Primus rating 300watts are dangerous if you are not paying attention, can it reach these wattages, yes, reach them safely, yes, but the operator needs to be paying attention constantly.
The basic formula is very simple algebra
(Your Watts)/Lowest Battery Charge Before Cutoff)/Mod Chipset Efficiency=Maximum Amps you will pull
Watts setting is pretty simple, you are wanting to know if the mod can do its max 300watts and for how long
Amps we know, you are using 30amp batteries
We are calculating for a triple series mod, so voltage of single battery X 3, giving us a range of 9.0v to 12.6v range (3.0x3, to 4.2x3 volts)
Mod Chipset efficiency, the circuits pull power to function, most this range is for a cheaper chipset about 90% where and Evolve DNA board has about a 98% efficiency, I don't know the chipset on the Primus so I'll take the lowest rating to play it safe, that is 90%
(300watts/Lowest Volts)/90%=30amps
300watts/9.0=33.3333333/.9=37.037amps <- Not going to work
300watts/9.6=31.25/.9=34.7222222amp <- Again not going to work safely
300watts/10.2=29.4117647/.9=32.6197386amps <- Still not safe enough
300watts/10.5=28.5714286/.9=31.7460317 <- Still not safe enough
300watss/10.8=27.7777777/.9=30.8641975 <- Getting closer
300watts/11.1=27.0270270/.9=30.0300300 amps <- Target Zone, 11.1volts which is about 3.7volts per battery on their charge, right at their median rated charge printed on their label, most mods display this at about their half charge level
So can the Primus do 300watts? Yes, in a very narrow, very short charge range 11.1v lowest charge up to 12.6 highest charge.
Is the customer/end user going to be happy with such a narrow range? No.
Is the mod safe for general user? No, just like a person driving a car with a license, the person needs to be paying attention and know the limitations of the equipment they operate.
Would you constantly drive a Ferrari at 200+ MPH? No, for one it is not safe because everyone else is not doing 200+ MPH. Not to mention the Ferrari is not going to last pushing it to its limits everytime, eventually you will blow the motor. Mods are not much different from the Ferrari, more along the lines of a high end gaming computer, push circuits to their limits they heat up, that heat if you can not control it will seperate and break down the circuit boards, eventually you'll destroy it. Just something to think about
