@mooch battery in DNA vs mech

[Outcast]

So I understand battery safety with mech mods now when it comes to regulated mods how dose it work is the amps to the coil off the board is that the drain on the battery I just ordered a dna 250 167watt mod I know in a mech ran in series if ur running 2x 30 amps it's still only 30 amps and in parallel "60" but count it as 45 amps now in regulated mods run series if I get the vtc6 3000mah that u put at 19amps would that mean I can't run anything past 19amp off what the board says is running to the coil

I apologize if this is a stupid question

With a regulated mod, you have to look at power rather than current. Actual amps into the coil(s) are not really relevant. And a regulated mod stresses batteries the most just before it cuts them off due to them being "empty", so for a rule of thumb, use 3V for calculation purposes. Go look at Mooch's charts for Maximum Vaping Amps, multiply that number by 3; that's how many watts a particular battery can supply when it's relatively new.

So vtc4 for the DNA 250 "2 battery" mod would be best?

Mooch explains it well in the link below. In a mech ALL the current load is placed on the battery because the battery is directly connected to the coil. In a regulated mod the electronics take the load and the batteries that power the mod are supplying power to the electronics which in turn power the coil. If you have multiple batteries, each battery supplies part of the current to drive the load.

And as I understand in the DNA software u can change what volt it calls the battery dead so u cut set it to 3.2 or something "I think"

Batteries can either supply high MAH (that translates to vaping time) or high max current (which translates to higher wattage). What determines that is the resistance (load) placed on the battery that supplies the power to the coil through the electronics.

The major benefit of a regulated mod is safety. You can apply a direct short to a regulated mod and it will just give you an error message and shut down. A mech will blow up in your pocket if the atomizer short circuits.

I'd look at 3 battery mods to supply 250 watts.

I got a DNA 250 throttle down to 166 watts 2 battery

How many watts will you actually be vaping at?

To get the full 166 watts, you're going to need batteries that can supply nearly 30A each.

But if you're actually vaping it at 100 watts, then 20A batteries are fine.

In eScribe you can set the soft cutoff to whatever value you like. 3.2V is fine, some go with 3V. You set your Wh so your battery indicator is reasonably accurate, and you either run battery analyzer for your particular battery, or get a curve from someone who already has like @Wingsfan0310 . They are battery model specific. The one that comes as "stock" is generically good enough under most circumstances.

As to battery used, I've just defaulted to 25Rs on almost all my mods. 20A is more than sufficient for my use. The 30Q is another excellent 20A option, and is rated at 3,000 mAh, 500 higher than the 25R. If you then ask the rationale for why I'm using 25Rs instead, I don't have one. It's just the way things worked out.
