Describe the bug
After selecting the iron flow battery chemistry, The voltage model choice is set to the table and the voltage model inputs are disabled. Clicking the electrochemical model option does not change the value of the voltage choice variable but it does re-enable the voltage model inputs which cannot be used for the iron flow battery. They should be greyed out as long as the iron flow battery is selected. The inputs currently are greyed out again when reloading the Battery Voltage Tab.

Expected Behavior:
The voltage model inputs should be greyed out as long as the iron flow battery is selected. Perhaps the voltage model choice RadioChoice should be disabled as well for this battery as the electrochemical model is not an option for this battery chemistry.
