What battery voltage and mAh would I need

I have 4 Hitec HS-322HD servos connected to a 6 channel maestro. I want to use a single battery to power them all. What battery voltage and mAh would be safe to use.

Here’s the specs for the servo:
Motor Type: 3 Pole
Bearing Type: Nylon
Speed (4.8V/6.0V): 0.19 / 0.15 sec @ 60 deg.
Torque oz./in. (4.8V/6.0V): 42 / 51
Torque kg./cm. (4.8V/6.0V): 3.0 / 3.7
Current Drain (4.8V): 7.4mA/idle and 160mA no load operating
Current Drain (6.0V): 7.7mA/idle and 180mA no load operating
Size in Inches: 1.57 x 0.78 x 1.43
Size in Millimeters: 39.88 x 19.81 x 36.32
Weight ounces: 1.51
Weight grams: 42.81

Thanks again.


You can use any of our 4- or 5-cell battery packs to power your servos.
