All three of the servos have a nominal operating voltage of 4.8 V to 6 V. The larger lift and tilt servos can briefly draw up to around 1.8 A each when commanded to move abruptly, but the typical current draw should be under an amp each. The stall current of the micro gripper servo is approximately 0.8 A at 6 V.
The Romi chassis has multiple power options built into the battery compartment, as discussed in [[Pololu-Romi-Chassis-Alimenter|Options d'alimentation]] of the Romi Chassis User’s Guide. If you are using the 4 battery configuration with the Romi chassis, you can power the servos from the battery voltage. Please note that using all six batteries in series can result in voltages upwards of 9 V with fully-charged NiMH batteries, so you should not power your servos directly from the batteries in this configuration. In this case you can use a [https://www.pololu.com/category/131/step-down-voltage-regulators step-down voltage regulator from Pololu}} such as our 6V, {{polpl|2859|2.5A Step-Down Voltage Regulator D24V22F6}} to safely power the servos.
{{ambox|text=If you use the {{polpl|3541|Power Distribution Board for Romi Chassis}}, it defaults to getting power from all six batteries, but it can be reconfigured to be powered from four cells; see the board’s product page for more information.}}
