How to supply power with a battery to the TX2?

Hello, I am currently working with the tx2 for a project that must be installed on the dashboard of a car and I don’t know how to energize it, I have a 11.1v 3s venom brand lithium battery but I have not tested it for fear of breaking it down ( I’m just a noob).
I also saw on Reddit that it could be energized with power banks like these:

I would greatly appreciate your help, best regards.

Hi, the input voltage range is 5.5V-19.6V (TX2), 9.0V – 19.0V (TX24GB/TX2i), the maximum power consumption is case by case, please search related topics in forum for more info. Basically 50w is enough for most use cases, you can choose power supply accordingly.
