✅ WattCycle First-to-Market: WattLINK - EcoFlow Delta 2/3 Series PPS Expansion Adapter Cable (M8 to XT150-Style)
- Custom EcoFlow-Compatible Interface: Designed for EcoFlow Delta 2/2 Max, Delta 3/3 Plus series, and WAVE 3 ports, this expansion cable supports high-capacity direct connection with bidirectional power flow (charging and discharging).
- 50A Bidirectional Rapid Charging: Engineered for speed, this parallel extension plug supports a maximum bidirectional current of 50A. When your 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°C 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 51.2V 100Ah battery and the portable power station each manage their own State of Charge (SOC). Users 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.
- Professional Value at $849.99: This bundle provides a massive 5,120Wh of Grade-A LiFePO4 energy—the same capacity as five standard 1kWh units—delivered through a professional-grade bridge for an industry-leading price.
- Size: 59 in
- Compatible with 48V series batteries: 48V 100Ah V2 rack smart battery, 48V 105Ah golf cart smart battery.

Received in good condition and appears good quality. Works as expected. Would recomend.

The product demonstrates commendable quality; however, its pricing for a standalone cable is rather high, which is reflected in the three-star rating.
