8700 Power Pack

8700 Power Pack is a TECHNIC supplementary set released in 1982. It contains a C-cell battery box, electric cables, a 4.5 volt electric motor and some basic TECHNIC parts to help add the motor to an existing set.
This set replaced 870 Technical Motor, 4.5V, the main changes being the new cylindrical style battery box, the change to 3-prong wires (to improve the reliability of the connection) and some additional elements for building gearboxes.
The successor to this set is 8720 9V Motor Set.
== Notes==
*Although rated at 4.5V, the motor can tolerate a certain amount of overdriving up to 12V (using a 7864 transformer) but it will eventually fail. The mode of failure is the shaft will overheat and melt the plastic axle, causing it to break.
