Hello, If you look at the detailed instructions here on our website: vorpalrobotics.com/wiki/index.php?title=Vorpal_Combat_Hexapod_Battery/Switch_Construction you can see there is a 3A 5V BEC feeding the servo controller. You cannot put battery power (at least not at the 7.8 volts we use) into the servo controller because you will burn up the MG90S servos which can't take more than 6 volts, plus the logic portion of the servo controller also needs 5V anyway. We also find that feeding the servos regulated 5V makes them last a lot longer, they tend to overheat during stressful activity at 6V.
Hello, have you directly connect the battery to the servo board ? is it enough or should I consider using a UBEC ?
