^^^ this is not being used by your battery driver. Do you plan
to use it in the future or is it a copy&paste mistake? :)

Hello, this is correct that driver doesn't use monitored-battery info,
but I was thinking that it's good to have anyways in the device-tree
because this completes hardware description + the gauge driver isn't
aware about maximal battery temperature. Hence it may become useful and
it doesn't hurt to have that additional information about battery cell.
