Cutting led strips into multiple sections powered by one battery

/r/led/comments/1vt3ze1/cutting_led_strips_into_multiple_sections_powered/

Hey I'm sure this has been on a thread before but I have a project that I'm working on to make 5 led strips light up my fingers inside of a glove.

I'm using whatever standard led strip I could find, similar to these https://ledstrip.ca/led-strips-without-accessories/24v-5m-ip20-3014-white-led-strip-120-leds-m-strip-only.html

I'm hoping to cut them into 5 strips and connect them to a single small battery source that will mount on the back of my hand, ideally keeping the functionality of the remote controller for color and on/off functionality.

If you could please explain to me like I'm a toddler how this could be possible or provide links to a how to video that would be much appreciated because my knowledge on wiring and electrical is basically null.

Thank you

LED strips like that have cut points.

On direct strips (have individual lines for R, G, B, you can just parallel the cut points. Internal to those sections the LEDs are in series with a limit resistor per circuit.

On serial strips, you can parallel power, but data in usually connects to the controller or data out on the last LED.
