Anyone recognize this battery connector?

Hi.
I have the draganfly IV helicopter, which uses
11.1 V Li-Po batteries, with the connector
shown in this photo:

Does anyone recognize the conector?
I've found a much cheaper source
for the batteries, but I need to get my
hands on several of the connectors,
since I have to mate the batteries
to the connector on the motherboard.
The vertical dimension (height) of the
connector is about 7/8 of an inch.
Thanks!

Looks like one of the Yazaki variants. Yazaki connectors are impossible for individuals to get. Cut it off the heli and put on something like a Dean's.

I believe the ones at Radio Shack are a Molex type connector. You can buy better quality Molex (brand) connectors from a commercial electronics supplier, such as Graybar. They are very similar to the photo you posted.

Lots of loss with connectors of this type. You're probably using a measurable amount of the battery power just getting through these connectors. Power that could translate into longer flight time and better performance.
As I think someone suggested, you'd be better off with changing out all connectors to something like a Sermos or Deans. You can find both through Tower, Hobby Lobby or probably at your LHS.

I don't recognize that particular connector, but it appears to be about the same size & type as the "Mini" Tamiya plug carried by Maxx Products (#2913)...
Fact is, this type of plug is notorious for power loss (voltage drop due to high resistance). There are much better aftermarket plugs available.
Cheers,

That's true, but the mating connector is soldered directly to the "motherboard" of the Draganflyer. However it's not an insurmountable problem.
I have one here at work, and it's actually fun to fly. I've been flying airplanes for 25 years plus, but helicopters are new to me and I am getting a taste of "newbie" orientation problems all over again. Fun challenge! And what a laugh with LiPoly batteries - 15 minutes hover time or so.
