I don't know if my
hex ohm's are serial or parallel. The power is regulated by a potentiometer & circuit board & are Mosfet protected also. They hit much differently than my other regulated
mods. I like the hit on the Hexes better.
Is this serial or parallel? I can never remember.

Frequently you can tell whether
batteries are connected series or parallel by a visual inspection.
If the + of one battery is connected to the - terminal of the other battery, they are connected in series.
If the - terminals on both batteries are connected to each other and the + terminals on both batteries are connected to each other, then the batteries are connected in parallel.*
In the mod pictureed, a clue is that the batteries are inserted with one having the + terminal up and the other having the - terminal up. This is to bring the + and - terminals near each other to make it easier to connect the - terminal of one battery to the + terminal of the other battery which would suggest a series connection. The remaining terminals would be individually connected to the circuitry of the mod.
The purpose of these two systems is to provide different kinds of power to the mod circuitry. Supposing that you have two 3.7 volt (nominal) batteries with 2500 mAH capacity, connecting them in parallel would give you the equivalent of a 3.7 volt battery with 5000 mAH capacity. If you connected them in series, you would have the equivalent of a 7.4 volt battery with 2500 mAH capacity. In either case you would still have 18,500 mWH (milliWattHours) capacity (66,600 Joules). It all depends on how the circuitry is designed as to what it requires in the way of supplied power.

(Note that certain load/charge balancing systems might require that only the + or only the - terminals are connected to each other. The other terminals would connect individually to the circuitry. This would allow separate charging and discharging circuitry for each battery so they wouldn't interfere with each other if they were of slightly different capacity or age. This would be fairly rare in vaping mods.)
