View Full Version : External Battery Pack Connector

March 24th, 2017, 03:02 AM
Trying to connect a 3xAAA Battery Pack to a motherboard...the board has the three pin external connector on it. The battery pack has the two wires coming off of it. I need to solder on a connector to the wires to connect it to the motherboard. I read you can use the front panel speaker connector / wire or possibly the CD-ROM connector for sound cards. Is the sound card connector really a viable solution? I have a bunch of these so using one as a connector would be ideal as the all the front panel speaker connectors I have are part of cases that are in use or going to be used.

Also, do OEM Cases have a seperate speaker connector or is it tied with the rest of the front panel connectors in one adapter that connects to the board? I may be able to grab a Dell or Compaq case and take it out of there if that is the case.

Thanks for the help.

You're probably looking for dupont connectors:

Can I use the speaker or audio connector cable and solder it to the battery pack wires?

EDIT - Google helps...I can use the cable....

You can, but sometimes the ground wire has a slightly larger pin hole which causes connection issues. Some of the 3 to 4 pin dupont audio cables have the ground wire doubled up on one end which can make a loose connection if it wasn't crimped properly at the factory.

I gave you a link to a kit so you don't have to cannibalize other computers in the future for connectors.

Appreciate the link....

Was trying to do it without spending any money. But may have to go that route if the cable doesn't work.
