## Parts needed

| Part | Count |
| - | -: |
| `100_10C` battery enclosure | 1 |
| `100_12C` enclosure cover | 1 |
| `100_11X` battery with attached cable and connector | 1 |
| `100_18X` charge port | 1 |
| `100_14X` battery switch | 1 |
| M3x12 Flat bolt | 2 |
| M4x8 Socket bolt | 4 |
| Threadlocker | As needed |

## Instructions

1. Place part `100_10C` such that the hollow portion is facing upward toward the ceiling.

2. Take the battery (part `100_11X`) and slowly lower it into the hollow portion of part `100_10C`, the cable should be on the opposite side of the cable cut out on part `100_10C`.

   There are three groups of wires and cables coming out of the battery:

   1. Switch wires (highlighted in purple): the thin black and red wires without a connector at the end.
   2. Battery power cable (highlighted in red): the cable group with a plug connector at the end.
   3. Charger port cable (highlighted in yellow): the cable with a charger port connector at the end.

   To see how to route the cable group properly, please refer to the video below.

3. Put the charge port (part `100_18X`) into the protruding mount at the back of part `100_10C`. Make sure that the battery power cable (highlighted in red) is in-between the two parts. Open the cap of the charger port as shown in the picture below.

   Take **2 of** M3x12 Flat bolts and tighten them into each of the two holes to secure part `100_18X` to part `100_10C`

4. Take part `100_12C` and align it with part `100_10C` such that all the holes on part `100_12C` align with the threaded insert on part `100_10C`.

   Make sure that the switch wires (highlighted in purple) are routed through the hole on part `100_12C`. Be careful not to pinch the wires.

5. Take **4 of** M4x8 Socket bolts and tighten them into each of the four holes to secure part `100_12C` and part `100_10C` together.

6. After the parts are aligned:

   > [!NOTE]
   >
   > **Not ready to apply threadlocker?**
   >
   > You can assemble without threadlocker while you check the fit, alignment, and orientation. When you are confident, disassemble as needed, apply threadlocker to the bolts, and reassemble them following these instructions.

   - remove **4 of** M4x8 Socket bolts one at a time in a star formation,
   - apply threadlocker,
   - then tighten them back to secure Part `100_12C` and part `100_10C` together.

7. Take the battery switch (part `100_14X`) and install it through the round hole on part `100_12C`. Follow the instruction in the video below to see how to do it the right way.

   > [!WARNING]
   >
   > **Remove the o-ring from the switch button**
   >
   > Remember to remove the o-ring from the switch button as shown in the video, or else your switch will not be able to fit properly into the hole.

8. After all is done, you can remove the plastic charger port cover and charge the battery using the provided charger.

   > [!WARNING]
   >
   > **Never charge battery unattended**
   >
   > For your own safety, please never charge battery overnight or un-attended.
