Placement of the temperature sensor on the busbar ? stupid?

I’m starting to build 2 batteries of 16cells lifepo4.

I was thinking about the placement of the temperature sensor.
Is it not a better idea to place it on the busbars so it will measure temperature of busbar if there is an issue with it and as it is placed on top of the battery, it will measure also the battery temperature.

The only downside is that the temperature will be a mix of the busbar and the 2 batteries near.

I often see videos of people checking the busbar with thermal sensor or infrared cameras.
This could be automatically measured by the BMS.
