Remember that in a parallel configuration, the amperage is double that of any single battery. The Samsung 25R, LG HE2/4, LG HG2, Samsung 30Q are all good, and rated to at least 20 amps. In parallel, then, they'd be ok to 40 amps. At 40 amps, you're safe down to .1 ohm...

I see differing opinions on parallel battery configurations, some say double the amps some say 75% of the total amp pool. I'm pretty sure @Mooch has stated the latter, if that's the case then this is the value I would go with.
Shawn recommended some great 20 amp CDR batteries, but 0.1 ohms is 42 amps which even if you are getting a pool of 40 amps is pushing it a bit. Also once you get into resistances below 0.15 you are playing with fire. The reason being that very few people have resistance meters that can be trusted to have sufficient accuracy that close to a dead short. A couple of hundredths of an ohm at that level make an enormous difference in amp draw. Also factor in that coils have drift in resistance once in use. Play safe, there are no practical reasons for pushing your safety this close to the edge.
Eg.
0.1 ohms = 42 amps
0.08 ohms = 52.5 amps

Ok sounds good. I had just thought someone had told me that it only doubles the amperage in series, not parallel. I have a couple of Sony vtc4 I was thinking of using. So to play it safe I'll try to keep my builds around the 0.2-0.3 range
Series doubles the voltage, but the amperage stays the same. Parallel doubles the amperage but the voltage stays the same. Theoretically...
What happens if you put one of the batteries in backwards?
Oh, noooooooooooooo...
In series, the amperage remains the same, but the voltage doubles. That means you would be pushing up to 8.4 volts to a .1 ohm coil, pulling 84 amps.
Boom!

Because a battery can loose connectivity at any given moment leaving only one battery to carry the load, the HG6 is the only battery I would use with those builds. It's just better to be safe than sorry when there is a battery that can safely carry the load.
What about the new Sony VTC6. I think they're 30A & 3000mAh. I think Sony rated them at 15A continuous
Well, then, that changes a bit. The Hex is not a mech and has circuitry to protect and prevent issues. And, the board in there is only rated (will allow) 30 amps.

I know , I was mainly asking about the Tugboat
A 20 amp battery. There are no 3000 mAh batteries with that high an amp rating. You're stuck with the 1500 mAh LG hb2/4/6. You can get a 25 amp battery with 2500 mAh (Sony vtc5a). That would be the best of both worlds.

There's a crap ton of bad, confusing info here.
First off, it's only in a regulated mod where series vs parallel represents higher voltage vs higher amperage... or with a given wattage.
But when you decide on a given resistance in a mech, series batteries shoots the current through the roof.
Also, MOOCH tested the vtc6 and has been noted saying he'd safely call it an 18 amp battery.
It IS NOT an option here.
20 to 30 amp batteries ONLY.
Check out Mooch's table of recommended batteries.
The warning @tj99959 gives is something seriously worth considering here.

In Mooch's recommendations the vtc6 is listed as a 19 amp battery, but in several other of his posts ("best 3000 mAh battery", "vtc shootout") it's mentioned as a 20 amp battery.

And in the video interviews he mentions it as an 18 amp battery and explains why.
Then goes on to say since vaping is strictly pulse usage, we can determine our comfort levels when using above the continuous rating.
And in at least one thread, even in the thread title, he lists the vtc6 as a 15 amp battery.
I feel most comfortable with 18 considering he stated that at a 20 amp continuous discharge, the vtc6 heated up past its "safe temperature".
