I expect to use a Lipo pack that will hopefully have the correct connector,
but I'd like to be able to add compatible connectors on other battery packs. Where
can I source connectors to mate with the JST 2mm connector on the Power Shield?
Here's the connector I use: http://www.digikey.com/product-detail/en/S2B-PH-SM4-TB(LF)(SN)/455-1749-1-ND/926846
Go to the bottom and check the "Mating products" section and there's several products to choose from.
I just noticed the other day that Adafruit also sells them. Usually more expensive than Digikey, but if you're already going to buy something else from them you could save on shipping.

It appears that this housing

with a contact like this

could be used. Is a crimp tool required to assemble the wire, contact and housing?
Sorry, I'm a software guy and need hand holding on things like cable assembly. :-)
Yes but you could crimp those with a simple pair of pliers if you're only doing it once and don't want absolute perfection.
Hand crimping with a good pair of pliers for a few connections can be done with patience, but it doesn't take very many to make it worth your while to pony up for a pair of knockoff crimpers like this pair from Pololu: http://www.pololu.com/product/1928 (http://www.pololu.com/product/1928) They are made in China, but the produce a very nice crimp without too much practice or effort. By knockoff, I mean that the "Official" Amp or Molex or JST crimp tools have an MSRP of $150 - $600. I suppose if I was in business making critical connections all day long I might pay that RE-donk-ulous price, but I would have to be making a lot of coin selling them before I would.
Just like the argument in the other thread regarding paying an extra 10 - 20 bucks for a "genuine" FTDI adapter that you will use regularly, making crimped connections that will be in use for the life of your project that you can rely on is worth a few bucks also. How many connector pins will you destroy getting a good crimp? How much time will you waste getting them all perfect, only to have one wire pull out after you inserted all the wires into the housing?
I'm cheap, and hard headed, and fairly skilled with a pair of needle-nose. My crimper came this past friday.

Thank you for the tool recommendation. Polulu is becoming a go to site as I
continue working with Arduino projects.
