What is “3s, 30c, 4500mAh” mean in a lipo battery/ RC battery ?
3 important factor :
1 The S rating: 2s, 3s, 4s– same as 3cell, 2 cell, 4cell
Each cell puts out 3.7volts DC, so a 3s is 11.1 volts
2 The C rating: The 20c, 25c, 30c rating needs to be used with the “mah” rating to calculate the allowable amp draw. The number of cells does not matter.
4500mah/1000 x 30C = 135Amps
135 amps is the maximum safe current a motor can draw from this battery.
3 The Mah rating: 4500mAh is 4500 milliamp hours or 4.5 amp hours. That is the amount of energy the battery can hold. This battery will give 4.5 amps of current for one hour. Or 9 amps for 1/2 hour, or 13.5 amps for 15 minnutes. Motor consume current.
