JR Servos and 4.8v
JR design their range of servos around the voltage of a 4 cell Ni-Cd or Ni-Mh battery. These batteries are rated at 4.8v but this is a nominal voltage for the battery pack. A 4 cell battery will reach slightly over 6v when fully charged.
With modern Li-Po and Li-Fe batteries being widely used, regulated power supplies are becoming common place in model aircraft to help keep the weight down, keep a stable voltage and to aid in high power situations on large aircraft with high power servos. The use of a regulated power supply upto 6v is fine to use.
However using a 5 cell Ni-Mh battery which is rated at 6v is not ok to use, this battery will reach over 7v when fully charged and may damage the servo. If you are looking to use this type of battery we would recommend the HV, WV or NX range of JR servos which can handle this extra voltage.
