LED 電源問題

Hello brothers
I'm adding LED to my big foot (already blown some LED on in the trial process )
so here's my new plan for the circuit

Concerning the power source, I'm think of using a separated AA / AAA battery pack or directly drain from the rechargeable battery.
If I connect the LED circuit to the battery before my ESC, will the LEDs dim when I pull my remote trigger?
Which do you recommend?

If for short period of use, will you use the lithium battery ( CR2023 - 3V ) just like the one used in our PC mother board. save  a lot of space.
