The H-Priv though it claims 220watts, it is hype, as there are no 18650 batteries that can handle full output, amps increase as the battery charge decreases.
220watts/6.4volts (3.2volts lowest charge per battery)=34.375/90% mod chipset efficiency=38.19444_ final amps (no battery can hold this amp load continuously, maybe for 1 second but that is it, battery shifts down to CDR)
220watts/7.1volts (3.55volts lowest charge per battery)=30.9859/90% mod chipset efficiency=34.4288 final amps (again, not even the Sony VTC3 1600mah, or LG HB2/HB4/HB6 1500mah true 30amp CDR batteries can handle this mod safely at full output)
Full 30amps that will run safely at 220watts you would not a full useful charge with it, by Ohm's Law, 220watts @ 30amps Continuous = 7.33volts lowest combined battery voltage at 0.24ohms.
Kooper Primus on the other hand being 3x battery series
300watts/9.6v (3.2v per battery)=31.25/90%=34.722222_ final amps
300watts/9.9v (3.3v per battery)=30.3030/90%=33.67 final amps
300watts/10.2v (3.4v per battery)=29.4118/90%=32.6797 final amps
300watts/10.5v (3.5v per battery)=28.5174/90%=31.746 final amps
300watts/10.8v (3.6v per battery)=27.7778/90%=30.8642 final amps
To get full 300watts @ 30amps CDR the battery cut off would need to be 10v and a resistance of 0.33ohms
Personally IMO to reach potential 220watts or higher with current battery technology with 18650 batteries, or at least do it safely. 220watts the H-Priv should have been a triple batteries series configuration, the Kooper Primus to get to 300watts it needs 4x batteries in series or a 2 set of dual battery series with the two sleds combined in parallel. Shift down from 6th and 5th gear to normal street 4th gear for now, research the devices and batteries better before making your purchase and getting yourself into trouble. If you are also following the hype of batteries offered by such companies such as Efest (biggest offender of over speccing their re-wrapped batteries), IMRen, Basen, Eizfan or any other battery company other than real manufacturers everyone buys from (these are Sony, LG, and Samsung), no one makes a 35, 40, 45, 50 amp Continuous Discharge Rated 18650, the 4 highest are the Sony VTC3, and the LG HB Series (HB2/HB4/HB6), all other companies buy up mostly the B and C bin discards that didn't pass authentic muster for Sony, LG, or Samsung to slap their own label on. Basic rule of thumb at the moment, to get CDR amps you have to sacrifice Mah and run time, to get Mah and run time you have to sacrifice amps and CDR.
Link in my signature has listings of the most trusted batteries on the market by application, also check out @Mooch and @Baditude 's blogs, they have a bunch of valuable information as well.
Not trying to make a scare here, but seriously be safe out there, those two mods could be potentially dangerous, especially being released this close to the Aug 8 FDA Deeming Regulations deadline, makes me worry they have not been tested properly, that is a lot of power.
alright i see bro. i saw on youtube it said more mAh less Amp and more Amp less mAh as it be.
for KOOPOR Primus 300 what max wattage can it reach for this battery ''US18650VTC4 18650 3.7V 2100mAh Rechargeable Li - ion Battery 30A Discharge - 4 pcs'' and this ''4 PCs of ICR18650 - 26FM 3.7V 18650 2600mAh Rechargeable Lithium - ion Battery'' ? are these both safe to use ? Thanks bro!
appreciated that was much info ! but i don't understand very well. i will do research and myself and it's very helpful bro!
1) Don't use any battery that is ICR, these are notorious low amp bombs when it comes to vaping. The US18650VTC4 is what we term just the Sony VTC4, it is 20 to 23amp CDR, but can be wiggled up to about 28amps CDR (but not suggested doing so constantly), the VTC4 has a long track record of safety and dependability, basically simple formula, for a 20amp battery you can get about 60 to 65 watts per battery, 30amp battery about 90 watts per battery. H-Priv /w VTC4s, being in a dual battery series, 7.1v (3.55v lowest per battery) @ 23amps you max out at about 163watts its upper limit, the Kooper at 23amps load about 10.65v at 245watts.
check out Steam Engine main page and use the "Ohm's Law Calculator" to help, all you need is 2 of the 4 variables click calculate and it fills in the other 2 blanks.

If you want to max out those devices I would only recommend the LG HB2, HB4, or HB6 (any of them). They have the highest rating of any batteries available to vapers.
If you find that they don't get hot with your style of vaping you might be able to use something like the Sony VTC5A.
If they do get more than very warm when you use them, back off on the power and/or take a pull less often.
Oh i see. one shop that they sell Smoke H-Priv 220 with 3000mAh Samsung battery with ICR so i decided to ask anyone who know that will fit and safe to use it while vaping. and i see another INR and ICR i don't know what the difference but now i understand about Amp now. Thanks bro you help me much
. i'll do research more!Thanks bro for advice! but that guy who told me to get this battery VTC4 2600mAh 30A ''US18650VTC4 18650 3.7V 2100mAh Rechargeable Li - ion Battery 30A Discharge - 4 pcs'' his youtube video '''' what do you think bro ?
VTC5 2600mAh 30A 3.V or VTC4 2100mAh 30A 3.7V ? both quite the same are kinda tricky for me to choose. which is safe ? Thanks in advance bro.
The VTC series of batteries are all strong, if used in the right application. The VTC3 1600mah is true 30amp CDR very low mah, the VTC5 maxes out at 20amps, more Mah and less CDR, the VTC4 has been a king for years because it sat in between its two brothers decent Mah (2100mah) and more CDR than its younger VTC5 brother but less than its older VTC3 brother at about 23 to 25amps CDR able to be pushed up toward 28amps (but this decreases the life of the battery over time stressing it harder than it was designed for).
But I'll say follow Mooch's advice, he tests batteries for a living is our resident battery stress tester.

Thanks bro this is lots of help ! Much info! Appreciated much
i'll choose them which is right for me No battery is safe, there's always a bit of risk. That risk goes up as the current level and battery temperatures go up.
The VTC4 is not a 30A battery. In my testing it was rated at 23A.
The VTC5 is not a 30A battery. It's rated at 20A.
Both of those batteries run much hotter than the HB series at high amps. You can use them but I wouldn't go over 75W-80W each, or so.
If safety is your priority then you want the batteries that run at the lowest temperature. No battery runs cooler than the HB series
searching for 18650 battery fit with Smok H-Priv 220w and 300w and i think still not fit well for me. i afraid if i order wrong item for my customer i'll be dead.
is this fit for smok H-Priv 220w ''US18650VTC4 18650 3.7V 2100mAh Rechargeable Li - ion Battery 30A Discharge - 4 pcs'' ? 20x2 = 40 so 60x2 = 120 so how can it reach 180 or 200w? really headache for me.
anyway bro i really love your explanation each forum you post about Battery explain . Keep it up! really helpful and easy understand graph you give us .

How can it reach 180 or 200 watts?
A single 20 amp battery, through a "regulated" mod's "boost circuitry", can generate up to 60 watts power. Therefore, two 20 amp batteries can provide up to 120 watts power. Three 20 amp batteries can provide up to 180 watts. Calculating battery current draw for a regulated mod
I'm not an electrical engineer, so I can't explain how boost circuitry works, but it has something to do with the term "pulse width modulation".
Since a "mechanical" mod doesn't have a processor or boost circuitry, the power generated comes directly from just the battery. So a mech running a 20 amp battery will be limited in the power generated by just the battery alone.
Having said that, I seriously doubt that you'll be able to get 200watts from any two battery regulated device. As IMFire said, for a 20amp battery you can get about 60 to 65 watts per battery, 30amp battery about 90 watts per battery. Any mod manufacturer claiming results above that is just blowing smoke.

If you think you'll actually use 180w or above the only option is to use true 30a CDR cells - LG HB 2, 4 or 6.
Run time (between recharge cycles) will be miserable at high wattage's.
Just me, I wouldn't buy batteries from the source you linked.

i know you won't buy but i don't have else where site to trust. there aren't any LG HB2 or HB6 only HE2,3 and there ain't any Samsung 20R too. well probably i go for VTC4 after all.. Thanks in advance.
illumn.com has LG HB2's and HB6's in stock
Liionwholesale.com has the HB2, HB4, and HB6 in stock
imrbatteries.com have the HB2, HB4, and HB6 in stock
orbtronic.com have only the HB6 in stock
rtdvapor.com have the HB2 and HB6 in stock
All of them also have the VTC4 and the 25R in stock, and they are the most highly suggested distributors here in the US, and also authorized resellers. If in the EU you can try torchythebatteryboy (UK Forum's resident battery tester) believe he has an Amazon distribution setup.
