QuestionOutcome
Do we want high side or low side switching?We will do low high side switching , and utilize NMOS to achieve this. using load switches. 
Will each board be ground individually? Or a star ground?Each component that we have to control will have a ground ran to a FET on chaos, this will switch the component on and offCurrently, grounds return back to power distribution. However, an alternate may be to use the chassis as ground. 
How much monitoring is required for the 12V aux battery?ASC only requires under voltage protection for the supplemental battery, more clarification is needed for WSCOnly monitoring voltage for ASC 2018. 

Not Doing

  • Charging the aux battery will no longer be handled by chaos
