It uses female blade sockets rated 6 A per circuit at 30 V — the current density tells you this is a power interface, not a signal line. The 0.098" (2.50 mm) pitch keeps the board footprint compact while still providing enough creepage for the 30 V working voltage. Gold plating at 11.8 µin (0.30 µm) on the contacts gives a solid middle-ground cycle life for a battery connector that sees periodic pack swaps but not daily reconnection.
Derate it above 80°C if the pack runs hot, but the -20°C to 80°C operating range already limits this to indoor or protected enclosures.
The 1-1473776-6 is the 6-position sibling in the same battery receptacle series. Both share the 0.098" (2.50 mm) pitch, 6 A per circuit rating, gold plating, through-hole solder termination, and the same -20°C to 80°C operating range. The difference is the position count — 10 circuits vs 6 circuits — which decides the BOM line match. If your battery pack needs 6 cell connections, the 1-1473776-6 saves board space; if you need 10, the 1-1473776-7 is the correct fit. No other functional difference between the two.
