|First question - When the DelTang Rx is switched on it checks the battery voltage and sets the LVC (low voltage cut off).
From the DelTang features page for a Rx.
3V for <4.3V measured at startup
4V for 4.3-6V
6V for 6-9V
9V for >9.1V
As you can see a fully charged 2S Li-Po battery gives 8.4V so the LVC is set to 6V.
These are the default options and can be changed by programming the Rx.
Second question - Yes, the Pololu maintains the rated output and the efficiency falls.
I change from a 1S to 2S battery if the loco power requirements are above about 300mA with a 9V Pololu.
