Larry,

I think the issue is that if you have a smart battery charger it
will sense the current draw of the fridge and kick the voltage
up to the "charging" voltage instead of the "float" voltage. This
will result in your batteries being overcharged while the fridge
is running.

Why not just run the fridge off the battery with the charger on it.
There's no danger at all this way....I wasn't trying to tell him to
operate it off the charger without the battery online.

Most 12 volt boat refrigerators today have Danfoss compressors with
brushless motors inside and an electronic motor control as a separate
unit or Swing compressors which are pulsed on 12 volts by
electronics. Running these units direct from the battery charger
without a battery as a buffer can be a $300 mistake. To learn more
