| | | Hi people, Can anyone explain in detail the difference (Or point where I can read about it) of using this power sources: 9 Volts AA LEGO battery box (6 batteries) RCX motor output (6 batteries) 8475 (RC Buggy) RC Unit (6 batteries) 9 Volt battery (...)

| | | | | (...) The difference is the amount of current provided - all can provide 9V, but each has a different current limit. The amount of power delivered to an electrical device depends on both the voltage and the current (in equations, P=I*V). The battery (...) (20 years ago, 7-Sep-04, to lugnet.technic)

| | | | Hi Patrick, (...) the RCX has a current limitation per output of 550mA and can provide only 330mA mean motor current according to the data sheet of the motor driver. For the battery boxes it depends on the batteries, the lower internal resistance (...) (20 years ago, 7-Sep-04, to lugnet.technic)

The more voltage the faster the unloaded motor runs, so then alkalines give you more speed than NiMHs. (...) (20 years ago, 8-Sep-04, to lugnet.technic)
