Hi, new member and practical newbie vapor

[Lo in LA]

Thank you. I've read Ohms law several times now and can't quite put the math to use. Sadly, I used to be quite good in math and science, but I'm afraid it's a use it or lose it skill, lol
I'll keep plugging until I can determine amps, watts, etc, but for now I appreciate your feedback
This community has been amazing in helping answer my question!

Ohms law is for mechanicals. You need not worry about that. The device regulates the current through the wattage.

I finally understand Ohms Law, now onto wattage and Amps. The links from BrotherBob were SO helpful!!

In the interests of keeping things simple:

The wattage setting you'll be using in your regulated mod is the best way to determine which battery(s) to choose.

If you use a good quality 15 amp CDR battery like the Samsung 30Q or Sony VTC6, then you are good up to 45 watts per battery; 90 watts using two; 135 watts for three batteries.

If you use a good quality 20 amp CDR battery like the LG HG2 or Samsung 25R then you are good for 60 watts per battery. If using a 2-battery regulated mod, your good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.

If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with a pair of 30 amp CDR batteries you could safely do 180 watts assuming the mod cuts off when the batteries reach 3.4 volts.

WATTAGE PER SINGLE BATTERY:
20W-45W:

Samsung 18650 30Q, 3000 mah 15/20 amp CDR
Sony 18650VTC6 3000mAh 15/20 amp CDR​

20W-60W:

LG 18650HG2 2000mah 20 amp CDR
LG 18650HE2 2500 mah 20 amp CDR
Samsung 18650-25R, 2500 mah 20 amp CDR
Sony 18650VTC5, 2600 mah 20 amp CDR
Sony 18650VTC4, 2100 mah 23 amp CDR
AW 18650 3000 mah 20 amp CDR​

30W - 75W:

LG 18650 HD4 2100 mah 25 amp CDR
LG 18650 HD2 2000 mah 25 amp CDR
Sony 18650VTC5A, 2500 mah 25 amp CDR​

60W - 90W:

LG18650HB6 1500mah 30 amp CDR
LG18650HB2 1500mAh 30 amp CDR
LG18650HB4 1500mAh 30 amp CDR​

Just because your single battery regulated mod allegedly can put out 75 watts doesn't necessarily mean you need to use a 25 amp battery. If you rarely vape over 40 watts then a 15 amp battery will nicely do.

I use a single battery regulated mod that allegedly will put out 75 watts, but since I tend to vape between 30 - 40 watts the Samsung 30Q do great and last me all day.

Thank you suprtrkr, I didn't plan to go much above 40W so I'm glad the batteries will do. I downloaded the manual while I wait for it to arrive and it says to use a battery with a minimum discharge of 25A. Do you know if that is so at 75W it wouldn't make the battery overheat? Or is there another reason for suggesting the higher amp discharge?
Thank you for your reply.

Perfectly correct. The 25A recommendation is for the full wattage. That's also why I suggested HD2Cs or VTC5As as they are.
