For best results with those zinc-plated connectors: get some LPS-1 (not LPS2, or -2.5, or 3) and put a drop on each one. This will help ensure full connection with no corrosion for the longest possible time. These bullet connectors are rated for 12 amps of current, which is how much the 750 uses on both the Black and Red wire circuit, so they are always running at full-load (redline, you might say...).
