Using your fingers, pull upwards until the battery is removed from its enclosure.
Do not use a spudger or other flat tools to pry in between the seam of the battery and the battery compartment, as it is possible to damage the battery.

Identify the black latch on each of the plugs that are connected to the PBCs.
Swing the black latch open by gently prying the front/extruding lip of the plug with a spudger or other flat tool.

Grab each ribbon cable and apply a horizontal pulling force (with respect to the LED control PCBs) to disconnect them from the connectors.

Insert the spudger below the LED control PCBs and pry to remove it from the plastic chassis.
The PCBs are held onto the chassis with a considerably strong double-sided tape. If the spudger is too thick and can not fit under the PCBs, use a thin plastic pick or plastic card.
