Each item contains:

• (1) AS150 Red Housing (Female)
• (1) AS150 7MM Bullet (Male)
• (1) XT150 Black Housing (Female)
• (1) XT150 6MM Bullet (Male)

These 4 pieces are honestly all you need to fully equip your charger to plug into an S1000 or S900 battery.

• I source my connectors from the same factory that DJI does, so they're 100% guaranteed to work with your octocopter.
