Just ordered a Sig 150w TC. Not too sure which batteries I should order for it. Anyone have the 150w and like a specific battery? Any help will be greatly appreciated!!

Need some help with a battery selection!

Right now I have 3 of the INR18650-25R in blue wrapping, same thing? Thinking of ordering some LG HG2's as well
Blue wrapped 25r's are the 25r2s. Same thing and they are workhorses.
So the ones I have now would work?
Abso-freakin-loutely! Vape on my friend!
Battery drain in regulated devices depends on your wattage. They pull as much current from the batteries as they need to hit the set wattage, regardless of the voltage/current needed to power the atty at that wattage. Because of this, they will pull more current from the batteries as battery voltage lowers, which makes choosing batteries somewhat more complicated.
At 100w, the Sigelei 150w will pull around 13 amps from fresh batteries and around 18 amps near the voltage cutoff. Any decent 20-amp cell will work fine for that. I use VTC5's and 25r's in mine.
Above that, you'll have to try not to run your batteries down below something like 80% or the device is going to start pulling more current than your batteries are rated for. 150w will pull around 20 amps from fresh batteries and 27 at the cutoff. For that, you'll want some VTC4's or maybe even LGHB6's, if the lower capacity doesn't bother you.
On the flipside, if you're staying at 75w or below, your device will pull 13 amps at the most, so you can try some higher-capacity, lower-amp options. You could pick up a pair of Samsung 30Q's for superior battery life. The LG HG2 would probably perform well at lower power levels as well, though its 3000mah capacity is exaggerated. In practice, it's closer to 2000mah... ...for high-drain, anyway.

I also order the UWell Crown tank too. Plan on running it around 70-80w. I have my Samsung 25rs and bought some LG HG2's as well. In your opinion, at that wattage would you still let the batteries get below 80%?
If you want my opinion, I don't think it's a big deal to run batteries a bit past their limits and I occasionally do so. It typically just strains them and diminishes their overall lifespan, though it also leaves you with far less of a safety margin, which is not wise to do if you are unfamiliar with your device or the batteries you're using. It's something that you have to do some research on before attempting.
But I'm not here to talk opinions. I'm going by the numbers, which I'm calculating with this. Switch the device type over to "regulated" and the mode to "power regulation." Ignore the resistance and plug in your wattage in the power setting box.
Now, move over to the third section, "battery voltage." This field is where you plug in the voltage coming from your batteries, which in your device on a fresh charge is 8.4v, though 8v is more realistic. If you type 8v in that box, the current draw for your wattage setting is shown in amps on the table directly below it (the dark blue one titled "battery drain.") That's what's being pulled from your batteries on a fresh charge.
If you want to see what it will pull from batteries at the cutoff, change it to 6v.
As long as the amperage shown for 6v is below your batteries' continuous discharge ratings, then you're in the clear.
For 80w, it will need 14 amps from what is basically a "dead" pair of batteries and that's the most it should ever pull, so the answer to your original question is yes. In fact, it is well within the limits for either of those batteries.
