Is there a way to have the PMU run a startup procedure? Kinda like the delayed turn off, but for when the PMU is initially powered up?

You could create a timer - which starts when pmu.batteryVoltage is say above 8-10v, then use the timer as the trigger for function(s) when the timer value is greater than X
