What kind of battery and wiring would be best for a Hitec HSB-9380TH servo motor
How long do you want to use the servo?
volts * ampere * time = watt hours
7.5 * 2 * 1 hour = 15Wh... the approximate size needed to move an e-bike one kilometer.
Hitec HSB-9380TH
Operating Voltage Range (Volts DC) 6.0V ~ 7.4V
No Load Operating Current Draw 250 mA
Stall Current Draw 2,100 mA

I will be using it for one minute to hold against 22lb-in of torque
Why did you leave that out?
22 lb.in = 352 oz.in
Hitec HSB-9380TH
Maximum Torque Range oz. / in. 472
Find batteries with a discharge rate of 2A and create a battery pack with a potential of 6.0 vdc - 7.5vdc. (per spec)
- AA batteries have a capacity of 2A - 3A at 1.2v (1.2v - 1.5v)
- Six AA in series = 1.2 * 6 = 7.2vdc (7.2vdc - 9.0vdc)
