The maximum output current ARCO prints for part 4603: its brochure's A8000-48V DETAILS table row "48V 9,630 (180) 4,173 (78) 4" J180 External Only Isolated Ground 49mm K6 (6 groove) 4603" (Maximum Output column 9,630 (180)), and the product page's Technical Specifications row "Max Output (Cold, 9,000 RPM) at 53.5V 9,630 Watts - 180 Amps". Maximum output is the cold figure at 9,000 alternator RPM. The product page prints "Sustained Cruising Output (Hot, 6,000 RPM) at 53.5V 7,383 Watts - 138 Amps" and "Sustained Idle Output (Hot, 2,500 RPM) at 53.5V 4,173 Watts - 78 Amps". ARCO says "cold" testing was done at 71 °F and measures "hot" output after 60 minutes at 3,000 RPM under a plexiglass shield.

ARCO's brochure prints the regulation of part 4603 as "External Only" (row "48V 9,630 (180) 4,173 (78) 4" J180 External Only Isolated Ground 49mm K6 (6 groove) 4603"). The product page explains: "These units will come with a terminal block and a P-Type harness. They will only work with an external regulator". A regulator is not part of an External Only unit; ARCO names its Zeus Bluetooth regulator for these.
