4 battery harness configuration

are we good with the + configuration for 4 batteries

EFS

Kind of propulsion/control ralated, using 4x 6200mAh batteries instead of 5000mAh ones.

The 6200mAh ones cost $96.09 and weigh 895g each (https://hobbyking.com/en_us/turnigy-heavy-duty-6200mah-6s-60c-lipo-battery-pack-w-xt90.html?___store=en_us ).

The 5000mAh ones cost $75.18 and weigh 838g each (https://hobbyking.com/en_us/turnigy-battery-heavy-duty-5000mah-6s-60c-lipo-pack-xt-90.html ).

Using 4x 6200mAh would weigh 228g more (6.58%) while having 2400mAh more capacity (21.43%). It would cost $83.64 (24.42%) more.

Sensing

Action items / blockers:

  • Sensor calibr/quality test next weekend @ efs

  • Mech needs to mount 360 lidar mount on Houston

    • Do we need a downward facing lidar mount? Do we have lidars we can use?

    • Is this programmed / ready?

Updates:

  • < Decision Documentation >

Mech

Sensor mounts

  • Pegasus mounts for rangefinder and op flow have existed for a while

  • Lidar mount for Houston exists, just needs to be mounted

Electrical

Sensor wiring

  • op flow & rangefinder sensor wiring checked on Pegasus

  • waiting for mech on lidar

Conformal coating on PCB

  • Is the conformal coating for waterproofing? Which PCB will need it? I think it was Nathan saying we will have housing for all pcbs so conformal coating is redundant?

EFS

Sensor calibr & quality test

  • Need guidance/pointers on how to do calibration and testing

    • What specific metrics need to be calibrated?

    • What metrics are to be tested and against what values?

  • How much is done so far?
