Jetson Xavier NX Developer Kit Portable Powering considerations

Hey everyone,

Bit of a noob when it comes to electronics.

I’m creating a robot that relies on a Jetson Xavier NX Developer kit.

My robot already has a big battery that has 12V DC and 24V DC outputs, and it seems that the battery current output is rated at 20 A.

Could I hook up my Xavier’s powerjack to the 12V DC terminal? Will the 20A from the battery fry the Xavier?

Or will the Xavier only draw the current it needs from the 12V terminal and 20 A is just the max output current?

Not quite understanding this.

Ideally I’d like everything to run off this big battery.

So if this does not work, I wonder what I can do to get the Xavier to adapt to my current battery. Add some resister circuit to drop the amps? Have the big battery charge a smaller battery / capacitor that charges the Xavier?

Thanks for your patience.

It is OK to use 12V input to DC jack on NX dev kit. Jetson only draw the current it needs.
