Printing

Print in the orientation shown and use supports where needed. Ensure that the supports don’t interfere with the 3d printed threads in the main housing. I have tested with PLA and have successfully discharged 4S batteries without any overheating of the plastic parts (all 3 bulbs were on). The bulbs get VERY HOT, DO NOT LEAVE UNATTENDED. I have not tested higher voltages than 4S.

Assembly

1. Using 6x 4-40 cap screws and 6x hex nuts assemble the bulb holders onto the main housing. Be careful not to over-tighten as the ceramic housings can crack.
2. Remove the housing from the 150 discharger module.
3. Connect the two pin pwm cable to the controller.
4. Carefully rout the light bulb wires in the slots and line up the two pin pwm cable from the controller with the slot in the housing.
5. Press the controller into the main housing, ensure that no wires are pinched.
6. Plug in the 2 pin pwm cable on the discharger module.
7. Either plug in the XT60 cable to the discharger module or cut and direct soldered to the xt60 pads.
8. Cut and solder the opposite end of the xt60 cable to the xt60 panel mount.
9. Install the xt60 panel mount using the 2x 2.5mm screws.
10. Tidy up the cabling so that the lid fits without pinching or compressing anything.
11. Install the lid using 12x 4-40 cap screws.
12. Place the light bulbs in the storage compartment and install cover.

Notes:

1. I lined the storage compartment with foam to keep the bulbs from rattling.
2. The discharger module design has changed, it used to come with a different connector. In this case direct soldering is the only option.
3. My pictures show additional red and black wires, ignore these as they are not required.
