In my opinion, those would be OK. But please understand that my opinion is worthless at any competition.

You may consider using a connector that is a bit more capable of handling high amounts of electrical current (Amps), especially for motors (CIM, Fisher Price) and the compressor, because the loss in that connector may really hurt your ability to drive well.

Go to an electrician's supply store and explain what you are trying to do (quick-disconnect for 40+ Amp circuits, 12 Volts DC, light & inexpensive) and they should be able to help you.

If you can get them, Anderson Powerpoles come in 45 Amp rating (they are a LOT smaller than the battery connector), we use them everywhere.
