Powering Jetson Tx2 with a 3s 5000mah 25c

Can i power my jetson tx2 with this type of battery?
This is what the pdf stands for:

“The NVIDIA Jetson TX1 and Jetson TX2 modules have a main power supply input,
VDD_IN, which is typically supplied from a DC power supply. To power the module
from a battery, the system needs the following:
 2S-4S battery”

but then comes this note

"Notes:

  1. VDD_IN maximum supported current on the expansion connectors is ~4000 mA.
    "

My doubt is the vdd_in stands for the barrel connector?

Yes.

As this topic, you can use 2.5mm x 5.5mm barrel connector.
