The "anti-spark" feature in these connectors is designed to reduce sparking that may occur when connecting or disconnecting the battery,
which can be particularly useful in high voltage and high current situations where sparking could be dangerous or damaging to components.

When purchasing an "XT90 Anti-Spark connector set, pair," you typically receive two connectors: one male and one female connector.
These connectors are designed to be mated together to create a secure electrical connection.
