EC3 Gold-Plated Battery Connector (Male / Female / Pair)

EC3 is the compact member of the EC connector family, sized for mid-size LiPo and Li-ion packs, chargers, ESCs and power meters on small and medium drones and RC models. Each connector uses 3.5 mm gold-plated bullet contacts in a shrouded, polarised housing; choose a single male, a single female or a male + female pair.

Key features

• Up to 60 A continuous through the gold-plated bullet contacts.
• Shrouded, keyed housing guards against accidental shorts and reverse-polarity connection — it mates one way only.
• Small and light, with a housing that is easy to grip when plugging and unplugging packs.
• Three options: male (pin) only, female (socket) only, or one of each as a pair.

Specifications

• Connector type: EC3
• Contacts: 3.5 mm gold-plated bullets
• Continuous current: up to 60 A
• Options: male, female, male + female pair

Solder the wires to the bullets, then press them into the housing until they seat. The female (socket) half normally goes on the battery so its live contacts stay recessed. EC3 and EC5 are different sizes and do not mate with each other, so match the plug already on your packs and charger leads.
