What barrel jack connector to use for power on TX2 dev kit?

I’m trying to power the Dev kit from a 12V LiPO battery, and I thought I had the right connetor, but apparently it’s not a “standard” barrel jack. I tried using these, but no dice. Does anyone know what’s the right connector dimensions to use?
