Here is handy solder fixture for JST-XH-2S 3 pin balance port. I found it really easy and fast to solder the terminal this way instead of removing them from plug. I used this to make and adapter for the son Traxxas TRX4M so we could use our other batteries through the balance port since they don't have the weird TRX4M connector. I used double sided tape under the fixture to hold it in place while soldering. There is two fixture on for thin servo wire and the other for the larger more common silicone wire. Enjoy.
