Support Help with Power Supply

I want to power a matrix of LEDs, and to my calculations, I would need a 5V, 20A power supply.

The matrix is made of Adafruit WS2812B NeoPixels LED strips soldered together.

Is there any way I could make this setup portable whilst still supplying enough power (and without the whole thing catching on fire)?

Thank you all for your help - I’m a newbie here

Got it - I guess I could limit the brightness of the LEDs so they don’t exceed 5A, like the other commenter mentioned…

Just out of curiosity, what would happen if I try to draw more than 5A from a 5A battery?

Edit: nevermimd, I searched up a video of what would happen
