DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.

The 3-pin Lemo connector for the GPI PRO 12/24 V system is from the 1S.303 or 1B.303 series, with sources differing on the exact designation.
Operators should choose between straight (FGG) and angled (FHG) Lemo connector bodies depending on available space at the battery plate.
Pin assignment for the 24 V rail must be verified carefully to protect the sled electronics from incorrect polarity or voltage.

Exact Lemo series designation (1S vs. 1B) remains unclear from available operator reports.
Connector orientation choice depends on the physical layout and available clearance at the specific battery plate installation.
