The voltage drop will still be lower, the connector loss is nothing compared to the loss in the cable itself.
I have done alot of testing on this and the connectors show over one volt drop at 2 amps but replace the connectors with 3 pin deans and over a 60" long extension of 22awg the total recorded voltage loss at 4 amps was 0.06V. the losses in the wire are nothing compared to the losses across the "stock" connector.
How is your servo booster project going Lynx???
