- It doesn't seem necessary to have the ability to monitor current in both directions for the aux battery, as charging will occur prior to the power distribution board
- Remove R20, and use a 0 Ohm for R22 to set the reference voltage to 0V. This will allow the current sensor to output a voltage from 0...3V, and use the same scaling factor as the DCDC current measurement. The only difference is that it will be double the value as the shunt resistor is also double the value.
- The flatpack dual p-fets seem to run at 7-8A without heating up, which is a significant improvement over the previous revision
