    As you have discovered, there are about 10,000 different LiPo batteries in the wild, and the list changes daily.  Close your eyes and throw a dart.

    This is what I did - it's probably not the most efficient.  Some posters on the forums recommend 4S batteries, but this is what works for me on my 3DR Hex.

    I bought a few of the $7.95 2200mAh, 3S, 20C batteries from Hobby King and made a parallel battery adapter.  (I decided to standardize on XT60 connectors for my batteries.  If you decide on a standard connector, change the wires on the battery pack one wire at a time to prevent accidentally shorting out the battery which would certainly damage it.)

    Here's my parallel battery adapter:

    And here is the parts list from Hobby King:

    4x #T2200.3S.20/8932 Turnigy 2200mAh 3S 20C Lipo Pack = $31.56
    1x #HXTBM4S/4176 HXT Lipo Monitor 4S. A must have for all lipo users! = $2.40
    2x #XT60/9572 Nylon XT60 Connectors Male/Female (5 pairs) GENUINE = $6.38

    I haven't received this battery yet
    1x #T5000.3S.25/14842 Turnigy 5000mAh 3S 25C Lipo Pack (USA Warehouse) = $28.99

    On one 2200mAh battery, I get about 7 minutes of flight.  On a pair in parallel, I get about 12 minutes.

    Hope this helps.
