JST part number for Ardunio Pro battery connector?

Anyone know exactly which battery connector is used on the Ard Pro? The website just says "JST", like that is a standard. It's not....JST is a company, not a connector! They sell hundred of different types. It definitely doesn't match the mini plug on the LiPro batteries I have. The center-to-center spacing on the pins is 1.9mm. (Maybe it is suppose to be 2mm?) The schematic on the Arduino Pro website, besides not reflect the board, doesn't list a part number either.

I just received an email from the North American rep, Rick Nunemacher.
The connector on the board is a PH Series, SMT, side entry header, part number S2B-PH-SM4-TB
The mating housing is PHR-2-K.
The mating sockets depend on the wire size, and are part numbers SPH-002T-P0.5S (30-24 AWG), SPH-002T-P0.5L (28-24 AWG), or SPH-004T-P0.5S (32-28 AWG.)

By the way, I received an email from him at 9:45 PM! I’ve also talked with him on the phone and he has always been very, very helpful. Great customer support!
