Lee,
If the meter is powered from the pack (not from the 12V aux battery)
then why would you need an isolated supply?
Isolation is only needed if you use the serial port. Its ground its
connected to pack negative. If you plug a laptop into it, the laptop's
common is connected to pack negative!
I would take a simple buck down converter (48V to 12V nominal) without
worrying about insulating the power supply
Sure; that's fine for simple applications.
