For a Mech Mod, it really comes down to what Battery are you using? So... What type of Battery are you Using?
For a Freshly charged Battery at 4.2 Volts, a .3 Ohm Coil would make the Battery provide 14 Amps. This is OK as long as you have a Battery that is rated with a Contestant Discharge Rate (CDR) of More That 14 Amps. So a Battery with a CDR of at least 20 Amps would be what you Should be using.
You also have to be Very Careful when you get down around the .3 Ohm Level on a Mech Mod. Because if whatever you use to Measure the Ohms is Slightly Off, the Actual Amps that the Battery must provide could be Higher than what you Think. Or what the Battery can Safely Handle.

Battery drain
Notice that when the Ohms are lowered to .2 Ohms, that the Amps go to 21 Amps. Now you are Exceeding the CDR of a 20 Amp Battery. And it is Very Common Inexpensive Ohms Testers to be Off.
Being New to Mech Mods, My Suggestion to you is to Not Build much lower than .5 Ohms until you get More Familiar with you Mech Mod and how to Calculate Amps.

From what i can gather this box can be set for use in either parallel or series and use's two batteries.
4.2v on fresh batteries in parallel mode.
8.4v on fresh batteries in series mode.
Did you make a typo on the 4.2v?
No Typo. But I thought the OP was using a Single Battery Mech.
So now the Question becomes is the OP running in Series or Parallel Mode? And What types of Batteries is He/She Using?
I presumed he would be using two batteries as he said its a series mod
When I saw the word "Series", I thought more of a Product Line than 2 Batteries in series.
BTW - I wonder how Many people use a 2 Battery Mech in Series vs. in Parallel?
I see your point, i went off and googled the mod just to make sure before i posted ... if he comes back saying his button or mod is getting hot because he's pushed his batteries too hard we'll blame You! HaHaa aa
I've been happy using Parallel's, i don't see the point in changing something that works really well plus the batteries last longer
Me also! I personally like Hot build's But i also like to have minimum amount of wire inside my atty's, reason being that i don't have to wait for my coil's to cool back down, obviously with the series mods you have to wrap much longer/bigger coil's to keep the resistance
I like 1.5-2 ohm dual coils in an RDA on top of my Noisy Cricket. Mostly i use 28g Kanthal for these builds, it vapes flavorful, the wire is quick, Amps are at 5.6-4.2. Stacking -more so on a hybrid mod- has its risks, but high voltage, high ohm vaping is a pretty descent thing, imo.
A 0.3 ohm build on a series mod will pull 28 amps. Ideally, each battery would handle half the load (14 amps each) but one will be pushed harder than the other because no two batteries perform exactly the same. In order to minimize this, you should use "married pairs" of batteries -- two of the same brand and model that always stick together. The married pair goes into the mod at the same time, taken out at the same time, and charged at the same time using the same charger. They are never to be used for anything else (as in don't take one battery from the pair and use it in a single-battery mod). Also, you need to frequently check the pair of batteries to make sure they are discharging equally -- if you put the batteries on the charger and see one is at 3.4 volts and the other is at 3.3 volts, they are becoming imbalanced, and the battery which is being discharged more is handling more than half of the total load.
I would recommend (true) 30 amp batteries for a 0.3 ohm build on a series mechanical mod. That way, even one battery can safely handle the load all on its own. I would also recommend not going below 0.3 ohms, and since you are running at twice the voltage and four times the wattage of a single-cell mod, you don't even need to go as low as 0.3 ohms to get massive amounts of vapor. A 0.3 ohm build on a series mod will give you 235 watts on a fresh pair of batteries. Even a 0.7 ohm build will give you 100 watts.

In a series unregulated mod the amp draw is not divided between the batteries. A .3 ohm build means 28 amps per battery. 30 amp batteries - LG hb2/4/6, not Sony VTCs - are a must.

As said above^^^^the load is not split between the 2 cells in series applications. A 0.3 would be close to the lowest ohms you can safely use and that depends on which battery's, age, condition and any number of unknowns.
I am fearful of the current trend with unregulated series or series/parallel mods available to newbs at less than $20 and up. It takes quite a leap of faith for me to use a series mod and a shxx ton of wire! I suspect voltage drop helps to fix some potentially 'extremely dangerous' happenings of late.
