I'm no expert but what I gather from reading that is that in a "series" (or stacked) you are doubling your voltage but the capacity and workload remains the same as a single cell.

Yes, but you have to be very mindfull when changing batteries to make sure to put the batteries in correctly or else instant fry.
The mech boxes for two batteries are usually parallel batts.
The regulated boxes that use 2 or more batts are usually series batteries with the exception of the vaporflask.
i thought it went both ways.. Stacked (series) you get 2x volts but (here's where I'm vague) half or amp rating of lowest rated battery.... Parallel you get volts of weakest battery and combined rating of the 2 batts.
With a PARALLEL box (both positives connected to the same place, both negatives connected to the same place), you do get DOUBLE AMPS
The samsung 25rs are only 20 amps, in a parallel box with 40amp-capable-wiring you will get a 40 amp limit. I run a parallel box with samsung 25r's myself at .09 ohms all day every day and its great, and keeps the batteries well within their limits
With a SERIES box (one battery positive connected directly to the other battery's negative), you get DOUBLE VOLTAGE, but the SAME AMPS AS ONE battery. That means you'd still have a 25 amp limit, but a .3 coil on a series box would pull way more amps than a .3 coil on a parallel box.The way to remedy this is to just build higher resistance.
I also run a series box at .4 ohms (8.4 volts because series) and its just as hard-hitting as my .09 ohm build (at 4.2 volts). Both of these setups are around the 150 watt area and are not pushing the batteries anywhere near their limits
EDIT: DO NOT MIX CHARGED AND UNCHARGED BATTERIES IN A PARALLEL BOX, if the voltages are too different, one battery will charge the other, and if youre firing a powerful build with this happening, you can seriously damage your batteries. That being said, parallel boxes naturally try to drain both batteries evenly and if you use a married pair, they will never give you a problem with draining batteries at different rates
