Did you do any cost analysis on using addressable led stips instead of buying the neopixels individually?
In fact, here's my recommendation that will avoid screwing up your RPi.
First, use an RPi A+. It's got the smallest form factor, one of the cheapest, and easiest to swap parts out without buying extra dongles.
Use this Fadecandy board. It does require LIGHT soldering.
These LEDs are nice if the lights are separate entities and they need to be in unique places. They are VERY bright and in my house, they're actually painful to look at when they're at full brightness. This string is a string of 50, but you can cut them to only be the number of LEDs that you require. If you only need 10 LEDs, then fine! Cut the first 10 away and use them. At full brightness, expect the full string to use 3A of power. 10 LEDs would draw about 600 mA at full brightness.
These LEDs are nice if your use requires them to all be thin and in-line with each other.
Buy these and your job will be MUCH easier connecting power to everything. You can then split a 5v power source (with enough amperage) to both units and you no longer have to worry about trying to draw too much from the Pi's USB.
A battery backup like this provides 22,400 mAh, so the Pi running PEGGED OUT, will draw about 240 mA and last about 93 hours, optimally. You won't actually get that. I'd assume 75 hours.
But then you've got to worry about the LED draw. The entire battery allows 2.4 Amps of power in total, so you're restricted to about 2.1 Amps after the Pi gets its cut. This means approximately 35 LEDs at the most.
Under full load, that battery pack will last, optimally, approximately 9 hours, 20 minutes.
You won't get optimal power draw because SOME is always lost during transfer as heat or whatever else. I would assume, on a bad day, about 5-6 hours because LEDs typically are not full bright white most of the time and the RPi won't be pegged the entire time.
Combine that with the USB battery that can be swapped out if you want to, you can have battery as long as you want.
