I have installed LiFrP04 batteries. Everything I read says to not use temp compensation. Can I leave the temp sensor hooked up to monitor the temps and just turn off temp compensation in the menus?

Battery Temperature Compensation

The Classic comes with a battery temperature sensor (BTS). This sensor raises or lowers charge voltage
based on temperature. Connect BTS to the BATT TEMP jack
The Battery temperature menu appears as T-Comp in the BATTERY MENU. In this menu
you can change the voltage compensation as needed

Presumably it doesn't have any practical min/max limits, so setting it to 0mV/degC would be "off"
