    Yes it's possible, depending on the ESC if it can handle 18.5V+
    About whether the mah and brand have to match...........well if you care for your batteries then yeah they should match. If you have one battery that is 500mah less than the other, the lesser one will go flat quicker and quite likely ruin it. Depends how you have your LVC set. If it were me, I'd get a low voltage alarm that plugs into the balancing port of the battery and monitors each cell in the whole pack. When just one cell gets below the set level an alarm will sound. Assuming you stop when you hear the alarm, everything should be fine. Something like this http://cgi.ebay.com/7-4V-14-8V-RC-Li...item5638522f17 would do the trick if you plan on running two different mah packs and from different brands.

    I'm using 2x 2S GE power lipos 4000mah from feebay. They aren't too bad. When they die I won't buy more of them, simply because equal batteries, or better even, can be bought cheaper.
    You are unique just like everyone else

    That for sure 2s+3s will balance your e-max more than 2x3s or 2x2s.

    put the 2s in motor side and the 3s in the other.
    you have to use same brand, mah, and c battery. here is the example for what i use:
    ***** ********* 5000mAh 2S1P 40C
    ***** ********* 5000mAh 3S1P 40C
    MMM 2x3s medusa 70-2300 | MMM 2sx3s 1515 1y

    What ESC/Motor are you running?
    EVX2 won't handle more than 4S total.

    A lot of people used to complain that the EVX2 wouldn't run right away
    on two freshly charged 2S packs. They would have to rock the steering
    back and forth to discharge the packs alittle, then the motor would run.
