Grab one of your battery tubes and put an endcap on one end with the green wire going through.
Seal the end caps by cementing around the edge.
If the fit is tight, you can use sandpaper to sand the inside edge of the battery tube to bevel it (just like you did for the main electronics tube).
Do the same steps for the port side battery tube.
