⚡ XT60/XT60i Hack: LFP Battery to Portable Station

You can use a 2kWh/5kWh Power Kit Battery + Polarity Adapter (AB-CONV-PLUG) as a massive external battery for portable units like the Delta 2 or Delta Max.

The Setup:

LFP Battery -> Polarity Adapter -> XT60/XT60i Cable -> Portable Station (Solar Input)

The “3rd Pin” (XT60i) Logic:

EcoFlow uses the middle 3rd pin to detect the source.

• Pin Grounded/Detected: Unit identifies as Solar (Full power).
• Pin Open: Unit identifies as Car Charging (Limited to ~8A).

Main Unit	Cable Type	Speed	Result
Delta 2	XT60i (3rd pin on)	500W	Works perfectly as a high-speed DC buffer.
Delta Max 1600	Standard XT60 (2-pin)	200W	Stable charging.
Delta Max 1600	XT60i (3-pin)	FAIL	MPPT Cycle Loop: The station tries to draw too much, fails, and restarts the MPPT every few seconds.

Hack Tip: If you are using an XT60i cable with an older unit like the Delta Max 1600 and it kept rebooting, simply cover the middle pin with tape or use a simple 2-pin XT60 cable to force it into the stable 200W “Car Mode”.
