Help!

Correct name for Losi/Walkera 2 pin battery connector


Anyone know the proper name for this 2 pin connector used on small packs?

sammylam and others claim it is a JST-DS

http://www.ebay.com/itm/2-Pair-JST-D...item27d8064740

But I can't find it in the JST wire to wire catalog

http://www.jst-mfg.com/product/searc...1&id=11&page=1

Wasn't able to find it in Molex or Amp either.

Anyone know for sure what it is?

Thanks

John

Anyone know for sure if that is the case?

Thanks

I think you're right jj604. But the Molex 51005/51006 series can have different numbers of pins.

Part numbers for the plastic housing:
The Losi Micro-T connector has 2 pins, so the part you want is a molex 51005-0200 (male) and 51006-0200 (female); also known as 51005-2P / 51006-2P.

Contact Elements:
The electrical contacts (crimp terminals) are parts # 50012 and 50013.

Cable pin housing 51006

Thanks.

I had come to the same conclusion.

JJ,

Glad you found it.

May I suggest that you photograph white connectors against a dark background. The show up a lot better that way.

Glen, totally agree. I normally use Green.

The contrast is a nice balance between showing up the connector and being too harsh.

The pic I included was pinched from a website. Hence the white background.

Better late than never?


I've also been trying to find the name for this little bugger used on battery packs for the Syma X5C. At this time I believe it is a Molex 51005-2P. I'm still trying to order one to see if it is in fact what the one I need.

FWIW mine looks just like the one in your photo.

That is correct. The 51005 is the "Receptacle housing" which is the bit with two wings that is on the battery and the 51006 is the one it plugs into.

The 51005 has metal sockets inside the palstic housing and is correctly termed the Female connector and the 51006 has pins so is the Male.

Unfortunately hobby vendors often call the battery connector the Male plug because the outer housing appears to fit inside the connector on the plane or copter and the connector on the plane/copter the Female just to confuse things!

The -2P indicates it is a 2 pin version.

Be aware also that this 2 pin connector comes in BOTH polarities (ie red and back are swapped) depending on the vendor. Losi and Walkera are opposite I believe, but I'm not a quadcopter flier..

Good way to smoke your new little shiny toy.

Moral. Check the wiring colour matches before you plug in the battery.

Here it is nice and concise (and available)...


The 51005-0200 is a 2-way 1-row MicroBlade™ Wire-to-wire Receptacle Housing made of polyester. It mates with 51006 male housing. The crimp housing is suitable for signal and wire-to-wire applications. This 51005 series receptacle housing can be used with 50013 crimp terminal.

Female Connectors 51005-0200

Contacts (crimp terminals) 50013-8100

Yep - and note especially that these are "Microblade" connectors not "Picoblade" connectors.

The latter are the small "tall"ones used at 1.25mm pitch as 2pin in Parkzone Ultra micro batteries and 3 pin in Futaba and Chinese micro servos and receivers, these are the larger "flat" ones used in the 2 pin Losi/Walkera /etc battery connections.

Molex 510050200


Hey all,

Probably way late to this party, but this thread was crazy helpful to me, so I felt like I should contribute in some small manner. Mouser right now has the best price on these connectors:

http://www.mouser.com/Search/Product...538-51005-0200

Running around $0.18 for the male and $0.22 for the female at qt. 10 ea.

Thank you SO MUCH for posting this. Super helpful!

I am not sure if this was mentioned in this thread or not but pay special attention to the polarity with any pack that has this plug as Losi and walkera are wired opposite polarity same darn plug. . I have no idea why this is but noticed this with my first quad purchase when I bought batteries for it.

After reading the thread I see Jj has already mentioned this. But this is something worth mentioning a second time so more see it.
