Product Features
Bidirectional Power Link: The expansion cable supports power transfer in either direction between compatible DELTA equipment and a connected battery system. The dedicated adapter simplifies expansion and charging configurations.
50A Heavy-Duty Path: The 8 AWG conductors support a 50A bidirectional connection. The heavier cable size reduces resistance across the 41 in assembly in suitable high-current systems.
Molded System Connector: The molded ABS connector fits compatible EcoFlow DELTA expansion interfaces. The integrated shell provides a more secure connection than loose terminal adaptation.
Ring-Terminal Battery End: The red and black leads terminate in ring lugs for direct attachment to suitable battery studs. The 8.3 mm lug holes fit compatible threaded posts and hardware.
Heat-Resistant Construction: The cable assembly is rated for temperatures up to 100°C / 212°F. The reinforced ends support repeated mobile-power and expansion use.
