EcoFlow Cables & Pinouts

XT150 Extra Battery Connector

The “Extra Battery” cable uses a modified XT150 connector with additional data pins.

Connector Anatomy

• Part Number: XT150-EF-F-P (Female PCB connector).
• Male/Female polarity: Standard XT150 gender rules apply.
• Main Terminals:
  • Red Housing: Positive (+) 48V DC.
  • Black Housing: Negative (-) Ground.

• Data Pins (Wave 2 / Extra Battery Port): The Wave 2 PCB and many Extra Battery ports use a 6-pin data configuration:

  Pin	Function	3ft Cable Color
  1	CAN-H	Violet
  2	CAN-L	Orange
  3	Wakeup	Blue
  4	SigOut	Yellow
  5	SigIn 1	Black
  6	SigIn 2	Red

  • Activation (Resistor Trick): On simpler units (Delta 2/Max), bridging Pin 4 & 5 with a 1k resistor can activate the port. Newer units (PowerStream, Delta 3) often require CAN bus “heartbeat” messages.

Solar Input (XT60)

The standard solar input uses an XT60 (yellow) connector.

• Input Limits: Respect the VOC (Voltage Open Circuit) limit of your specific unit (e.g., 60V for Delta 2, 100V for Delta Pro).
• Over-paneling: You can exceed the Amperage (the MPPT will just clip it), but never exceed the Voltage.

Universal Compatibility

• Cable Types: EcoFlow sells different cables for Delta vs. River series. They are largely electrically compatible for power, but data capabilities (like Smart Generator auto-start) might rely on specific pinouts.
• Regional Variants:
  • Europe (BKW): Offers a specialized right-angle cable (BKW-Battery-Cable-Delta-EB) for the PowerStream/Micro-inverter setup which is much more flush against the unit.
  • Alternator Charger: Also features a right-angle connector, though it is often not sold separately from the full kit.
