What are the best batteries to use in Sigelei 150 watt Temperature Control

[Raistlin908]

I just picked up a Sigelei 150 W/TC control and a Smok TFV4, I want to run between 75 to 120 watts, what would you guys think would be the best and safest batteries to use? Samsung 25r? Sony VTC4 or 5? Any others I should look at?

I run 25R's in all my mods. I never have any problems. The Sony's are really good but they are expensive and even then you have to worry about fakes. Can't go wrong with 25R's imo.

Cheers,
Steve

Get the 25Rs

See if you can get Brillipower. I use them in all of my mods.

The 25R and VTC's are fantastic batteries, you won't go wrong using them. But at 60W max per battery, if limiting use to 120W total, I recommend the 3000mAh LG HG2 so you can enjoy the greater time between recharges.

Agree @Mooch I picked up a couple HG2's to use in my single 18650 devices. I get over 36 hours of moderate to heavy vaping in my Sigelei 75 at 50watts and 400 degrees. I'm going to pick up some more for all my mods! Very impressed!

I like my HG2s just fine, but... with so many mods using 3.6 or at best 3.5 as a cut-off, does much of that extra 500mAh live below the cut-off? I'm not sure they're worth the extra 25% cost, for most applications.

I put a pair in a 65w Smowell with the stupid screw on batt cover. Make that bitch last as long as possible, since I'm not opening it up again till they get weak.

LOL...

Interesting point! Down to 3.2V @ 20A (a common mod cutoff voltage) you get about 15% more capacity from the HG2...IIRC. Not too far off the theoretical 20% increase. Not sure at higher voltages.

For me though, 15% is worth a couple of dollars more for a cell, even more. They last for over a year but I get to enjoy that extra 15% almost every day. But I know others feel quite differently than I do.

I cant speak to higher quality mods but... none out of my i100, Sig75, D2, SMOK 65 or VTC go below 3.5v, according to my LUC4 (haven't tried a DMM to check).
I just got the Cube II today so that may be a bit better.

ETA: I should say... I rarely go to batt low anymore. Maybe I should try again with each and let it sit then hit again till true cut-off. I guess a more honest estimate would be 3.4 ish. Damn, I really don't feel like testing this.

Ahhh....
By the time you get your batteries out of the mod and into the charger their voltage has risen back up a lot. The cutoff for the ipv d2 is 3.2V and I suspect that could be the same for your other mods.

Does the mod use the sagged voltage to determine cut-off?
I could see that being the difference.

-Hmmm, no that would be even lower... awww, I has a confused.

I once has a confused...me doctor made it go away. But those shocks hurt!

The mod can only read the battery voltage at the terminals so any battery sag will be part of that reading. Since there are so many different batteries, with varied degrees of sag, the mod can't compensate unless it makes broad generalizations for different current levels. The mod could have a table of values to add to any voltage it reads, based on what the discharge current level is. For example, it might turn off at 3.2V at 1A and 3.0V at 20A.

I don't know what the mod's actually do though, except for the low voltage spec they list. I would suspect that if they had some sort of sag compensation that it would be part of their advertising?

Technically the cutoff voltage for my Koopor Mini is 3.2V however, at 60w it will refuse to fire at 3.5V. That's with HE4, 25R, HD2, HB6, HG2 and VTC4. If I turn the power down I can continue vaping.
