Remove heat shrink

To easily pass the wires thorugh the adapter part, we'll need to unsolder the metal ring from the wires. Use a blade or flush cutters to remove the heat shrink to expose the soldered portion. 

Unsolder metal ring contacts

Use a helping third hand to hold the metal rings while you unsolder each from the wire. Set the metal rings aside so you don't loose them!

Clean up wire holes

Go ahead and clean up any strings left over from retration. You may also need to widen the exit holes a bit so the wires can pass through, you can use tweezers or a screwdriver to help the wire fit through.

Loosen mounting holes

The mounting hole will be easier to screw through by widening them up a bit with tweezers or a screwdriver. 

The negative and positive connections are reversed on Canon batteries, so take note of the arrangment if you are adapting a different battery.

Bend metal ring

The metal rings will need to be bent so they can make proper contact with the connection pins on the LED panel. Bend the metal rings 90 degrees at the base of the ring like in the picture. 

Run wires through pin cutouts

Pull the wires all the way through the pin cutouts to make it easier to resoldering the rings back on to the wires.

Resolder ring to wires

Use the helping third hand to hold the bent ring while resoldering them back to each wire. Position the bent corners so they are pointing away from the center.

Recess connections

After the metal rings are resoldered, push the wires back into the port slots as seen in the picture

Nest connection rings

 Push the two connections rings inside the part until the metal is held against wall.

Insert screws to adapter

Use the included screws that come with the battery holder to fasten the battery holder to the adapter. Alternatively, M3 screws can also be used. You may need to apply force to the screw while mounting. 

Mount screws flush to the adapter bottom

Make sure not to fasten screws the screws all the way through the holes. You'll want the screws to be flush to the back of the adapter piece. 

Clean up

Remove any excess material around the screws after mounting so the 3D printed part lays flat agaisnt the back of the LED panel.

Lights, camera, action!

Add a battery to the holder and slide the adapter portion into the LED battery slot. If the adapter doesn't fit inside the slot, make sure the screws are not protruding all the way through the back of the adapter.
