WattCycle 48V Expansion Cable for EcoFlow Portable Power Station |
Note: This cable is designed to connect WattCycle 48V batteries to the EcoFlow portable power stations.
It is not compatible with 48V batteries from other brands.
PRODUCT DESCRIPTION
Specially Designed for EcoFlow Delta Portable Power Stations: Dedicated high-performance expansion cable for EcoFlow Delta 3/2 series portable power stations ports (XT150-Style connectors), enabling direct high-capacity connection with bidirectional charging/discharging support.
Two-step Easy Connection: Simply connect the M8 terminals to your WattCycle 48V battery, then plug the XT150-style connector into your EcoFlow power station. In just two steps, the WattCycle 48V battery works as an external expansion battery for EcoFlow, allowing you to easily increase your available power capacity.
50A Bidirectional Rapid Charging: Engineered for speed, this parallel extension plug supports a maximum bidirectional current of 50A. When the SOC of your EcoFlow portable power station is low, it can be recharged significantly faster through this dedicated link than through a standard solar power connector.
Industrial-grade 8AWG Construction: Built for the long haul, the cable features thick 8AWG wiring and a 100℃ heat-resistant ABS housing. The robust structure is designed to withstand repeated plugging and unplugging while maintaining total thermal and electrical stability.
Independent Energy Management: The WattCycle 48V 100Ah battery and the portable power station each manage their own SOC(State of Charge). You can ensure smooth operation by matching voltages before connection. If a large differential is detected, the power station’s native internal protection will simply pause the link until synchronized.
