When it comes to motor connections, surface area is your friend...
Clips are convenient, but also the worst, because they have minimal contact with the battery terminals. This mean delivering the current demand of the motor through poor, minimal connections causes your battery to work harder. It MUST DELIVER the current demanded of it; good old Ohms Law tells us that.
But making it to do so through the power robbing impedance mismatch of minimal connections forces it into an Overdrive state. Now, add several of these mismatches along the wires of the system… and you shorten the batteries charge life and potentially it's service life.
(This also applies to charging, in reverse).
The best connections are broad, flat ones that match the surface area of the battery terminals. The ones on your car are a good example. From there, connections to your driven devices should be made via wide, flat spade type connectors. Another good alternate would be the power plugs used by the car audio guys.
The ideal state of affairs is a straight, UNBROKEN, multi strand wire, properly sized to meet the current demand. This is impractical in mobile, float–tooning applications however
The next best thing is to have the minimum number of connections, and to ensure they each have a surface area matching the wires own surface area. Affix such battery connections permanently to the battery and make your interconnections with spade plugs.
