JST Female 2 Pin Connector-10Pcs.

It sounds like you’re describing JST (Japan Solderless Terminal) or BEC (Battery Eliminator Circuit) connectors, which are indeed commonly used for battery and motor connections in small electric planes. These connectors are often found pre-made and can be challenging to find individually.

When labeling JST connectors, it’s essential to consider the gender of the metal contact rather than focusing on the plastic housing. This ensures proper compatibility and connection when assembling or using the connectors. Using crimping tools like the Economy or Deluxe Crimping Tool can help secure the terminals onto wires effectively, with the Deluxe tool typically providing a higher-quality crimp.

Remembering to prioritize the gender of the metal contact helps avoid confusion and ensures the connectors are correctly identified and utilized in electrical connections.
