What is a suitable portable power supply for 5 servos?
Some articles claim that using a voltage regulator would work, others say to use a higher power battery preferably a LiPo battery.
The servos used are 5 Micro Servo SG90 servos.
So if a 9V could be used what is the appropriate method?
If instead of using a 9V battery a LiPo should be used what should the power of the battery be?
