Note for the Nomura SPI connections, we will not be using the GND pin on the microfit connectors, as we don't want GND loops, and the GND is already on the barrier blocks.
The Nomura Ideal Diodes had much fewer and smaller capacitors - are they all necessary? And what about the FETs - it looks like there will always a direct path from battery to panel through the body diode of the FET (by the way, thanks for adding those!). I'll go over this a little more later
Could you double check the thermistor connections and the filters on these? I think we want 1x3v3 and 1x thermistor sense for each thermistor, unless they will be broken out somewhere else.
Are the relay and the fuse in the low side or high side of the circuit? - should always be on the high side.

Off-board short to GND from the thermistors - we should put the resistors on the high side output.
Do we want an aggregate voltage measurement of the voltage - NO, see below
When the relays are closed, this will be forced to be the battery voltage
When the relays are open, there will be no current flowing, so we have an accurate voltage measurement from the individual I2C voltage measurements
The voltage measurement on-board will give an indication of the direction of current flow when the relays are closed. Since we also have a current sensor, and block the reverse current with the ideal diode, this is not required
Are the temp sense buffers required?
This is to decrease the impedance seen from the ADCs, but is it low enough already?
ADCs should have specs on max impedance
