Description
Overview
High-current lithium battery connector with mounting ears, in 2, 3, 4, 5 and 6 pin versions, rated 15A. Male, female and matched male/female pairs are available so a battery pack and its docking receptacle can be built as a set.
Specifications
- Pin counts: 2P / 3P / 4P / 5P / 6P
- Options: male only, female only, or matched male + female pair
- Rated current: 15A
- Mounting: integral ears with screw holes
- Type: battery docking / quick-disconnect connector
Purpose
It provides a repeatable, keyed connection between a removable battery pack and its housing. Extra pins beyond the two power contacts carry signals — temperature sensing, communication or charge-enable — so the BMS can talk to the device through the same connector.
Applications
- E-bike and e-scooter removable battery packs
- Battery docking stations and swap systems
- Portable power packs with signal lines
- Equipment needing keyed, repeated connection
How to Use
- Choose the pin count for your power and signal needs, and select male, female or the matched pair.
- Screw the connector down through the mounting ears so it cannot move when the pack is inserted.
- Solder the power pins with adequate gauge wire, and the signal pins to the BMS or controller.
- Keep the power contacts within 15A; use the signal pins for sense lines only.
- Check the connector seats fully and that the keying prevents reversed insertion.
- Lithium battery PACK assembly: Assembly of battery packs for e-bikes and energy storage systems.
- Battery equipment maintenance: Replace damaged battery connectors.
- Portable power station: Connection of battery packs for outdoor portable power supplies.
- Electric equipment: Lithium battery connection for e-bicycles, power tools and mobility scooters.
- DIY modification: Design quick plug structure for homemade lithium devices and battery packs.
