Will be using these at about 70w at 0.15 ohm so need at least 25+ amp rating.
The vtc4 isn't a 30 amp battery though, just to make that clear. A better option than the highest amp-rated battery in a single-battery mod is to go for a dual-battery mod. That way high capacity 20 amp batteries can be used. 70w from a single-battery mod will result in abysmal battery runtime.High MAH and high amperage aren't found in lithium batteries. You get one or the other. 30 amp batteries (which you need) are going to be in the 1500mah to 2000mah range.
At 70W and .15 ohms you are going to be at 22A and 3.2v on a mech. If it's a regulated mod all that will be controlled for you. Just find the battery with the highest MAH rating at 30A. Sony VTC4 is a good choice. Buy them when you can find them. Sony is restricting the sale of them to vape suppliers.

Although a great battery, the Sony VTC4 is only a 23 amp continuous battery as bench tested by Mooch. Battery vendors have misinformed their consumers that it is a 30 amp battery. That is true only if the VTC4 is used in a battery pack with battery protection circuits and active cooling. Without those conditions, the VTC4 overheats to dangerous levels if pushed. Vapers should consider the VTC4 as a 23 amp continuous battery.At 70W and .15 ohms you are going to be at 22A and 3.2v on a mech. If it's a regulated mod all that will be controlled for you.

26650 batteries do not handle high current well due to their construction and slower heat dissipation rates.30A operation is on the cutting edge of 18650 battery capability right now. Most of the batteries that can hit that target are in the 1500mah range. I picked the Sony just because it delivers a better MAH run time than the other choices.
We might see the 26650 begin to appear in sub ohm mod designs for that reason.

The Best 18650 Batteries for Vaping
26650 batteries do not handle high current well due to their construction and slower heat dissipation rates.
Yeah but the OP did say .15 ohm.And no type of mod used. Just 70 wats so I am assuming regulated?
and unless you want VERY short vape time at least a dual battery mod.
With a dual battery mod and 70 watts regulated the 30Q or the HG2's will both work fine. And give maximum 18650 capacity.
You inadvertantly contradicted your statement.In the ecig mod market size is critical. We all want smaller hand held mods that deliver longer vape time. if sub ohm vaping grows, then the tech to supply the market will evolve. There's new tech going on in the lithium market now for multiple applications. Most of that comes from research for electric cars. We will benefit from that research.
You inadvertantly contradicted your statement.
The manufacturers of lithium batteries are and will cater to their market, which is the auto industry and OEM power tool manufacturers. This market is looking for higher capacity batteries, not higher current batteries.
You're sadly mistaken if you believe these manufacturers (Lg, Samsung, Sony) are interested in the ecig market. The ecig market makes up only a small fraction of their consumer base. In fact, most don't even want us to be using their batteries in mods. Sony has been quite adament about this:
The companies who rewrap the batteries purchased from Lg, Samsung, and Sony and market those batteries for sub-ohm vapers are in reality doing vapers a disfavor with their over-rated specifications. The rewrappers are conning their customers for a quick buck and possibly putting their health in jeopardy by doing so.
Conflict 60A 3500mAh 18650 Bench Test Results...a dangerously overrated 20A battery!
Agreed. However, the ecig market will only develop new gear dependent upon the current availability of batteries presently available.I agree with what you said, but I meant that ecig manufacturers will develop what the market wants. The tech (in the battery market) will grow and I mentioned electric cars as an enabling industry that will cause better batteries to be produced. By better batteries I also mean safer batteries. The lithium cells in cars are an incendiary problem too. No one wants a car with a history of battery fires.
Again, by focusing on sub ohm coils you're focusing on the wrong thing. High/low wattage the key factor. As you yourself mentioned, you're a low wattage vaper but are using sub ohm builds.I agree with what you said, but I meant that ecig manufacturers will develop what the market wants.

The tech in the ecig mod market will evolve to meet the demand for whatever sells. Our ecig mod batteries came out of the tool and flashlight market even before electric cars were widely sold. Niche markets have always grown by utilizing components that were designed for other products.
I'm a 10 watt vaper who wouldn't care if sub ohming went away, but there are those who enjoy it.
Agreed. However, the ecig market will only develop new gear dependent upon the current availability of batteries presently available.
I think we're about at the limit with the batteries presently available. 65 - 75 watts is about the limit for the best 18650 batteries available; to get more power multiple battery mods are required to reach upwards of 200 - 250 watts.
My point earlier was our gear will not advance much farther based on the demands of e-cig consumers alone. The auto industry and OEM power tool manufacturers will need to demand higher current batteries before the battery manufacturers will create them (if technically possible). I don't see that happening because that consumer market places a higher demand on capacity than current handling.
