Rover Docs why so many battery monitor settings

I was just reading through the rover docs under full parameters and was wondering why there is at least 10 battery monitor settings, is this an error?

In the near future there will be other options to use battery monitors for. So you could have 2 power modules plugged into a Cube carrier board and then 6 more plugged into the AUX ports all to monitor and record battery/fuel systems on vehicles. The 10 possible instances of battery monitors is for future flight controllers that might have 10 ways to monitor batteries/fuel.
