The BORG uses (3) each 12 gauge "split ends" cables on POS and NEG terminals. These power supplies use individual circuit traces as seen in their printed circuit boards. Hopefully the images and text up the upcoming M&M articles will show images and text. I dumped the 3 12's into a six gauge distance four inches. This has seen 93 amps with negligable voltage drop. 3 12's = 9 gauge to handle 46 amperes. The M&M's really should be modified for extensive running all-out. 80 amp rectifiers and Panasonic low ESR capacitors plus max ventilation. Yes even the RSP can use the upgrades. The stuff is waiting in my delivery box. Landy the 80 amp rectifiers dropped Vf by almost a half volt in the Megawatt and that is not peanuts. But again this is for extensive all-out maximum charge rate. That's a lot different than using the M&M's to augment the existing onboard converter. Hopped-Up the M&M's become Mean little mothers. Rambo grade units. But hah (!) Maybe 1% of M&M users want or need that kind of snot. Dialed back to 80 really reduces heat as evidenced by hand over louvers.
