Placement and wiring of battery thermocouple

and on the principle that ignorance is NOT bliss, I see the need to have some sort of thermal monitoring of the general firewall space, in particular the battery. The EarthX ETX900 battery is rated for a maximum operating termperature of 60 Celsius.

From the EXT900 manual

There is an additional margin to 85 Celsius to allow for ground soak. If this proves a problem on hot flying days, it might help to open the cowling hatches after such flights.

I have decided to install another patch thermocouple to the battery, to verify that this constraint is met in actual flight.

This thermocouple will also be connectorised, with a separate jacketed loom, and will be connected to the CHT6 inputs
