Then you're minibot is not operating at max power at 5 amps current draw for two motors. There is a large difference between what these motors were designed for and what we are doing with them. The question still remains why not fuse each motor? It doesn't enhance performance, and, in fact, will add some resistance to the circuit, lowering performance. Are there any electrical engineers that would design a circuit like this without proper component protection? I hope FIRST will have a lot of replacement units at the Regionals and Championships. You're depending on both motors to split the 5 amps. what happens if one motor quits during a climb, and the other takes the full load?
