Sydewynder- No, it does not. Typically none of the aircraft ESC's have proportional brakes because all they are designed to do is stop the motor for a folding prop. They also have no neutral or "coast."
TSR6- The diode is built into the charging jack and prevents reverse polarity. This mean it will not read the peak as the battery voltage starts to drop. You also can't discharge through it. You will need to connect to the battery directly to charge it.
