’S’ number - # of cells in series
Slide 93

3.7 volts / cell
’S’ number - # of cells in series
3S = 11.1 volts
4S = 14.8 volts
Slide 94

milliamp hours (mAh) - the amount of power the battery can hold
1000 mAh battery with 1000 mA load will last 1 hour
1000 mAh battery with 500 mA load will last 2 hours
Slide 95
Slide 95 text
what does the ‘C’ rating mean?
‘C’ = capacity
e.g. 20C battery can discharge safely at 20 times the amount the
battery can hold
20C battery (1000 mAh) = maximum sustained load of 20,000 mA
maximum safe continuous discharge rate
