Selecting the correct connector for your Lithium-Polymer (Li-Po) battery is crucial for ensuring reliable power delivery, safety, and compatibility with your devices. With various connector types available, it's essential to understand their specifications to make the best choice. Below, we break down the key factors to consider when selecting a connector for your Li-Po battery.
Key Factors to Consider
1. Pitch Size (PH)
The pitch size refers to the distance between the centers of two adjacent pins in a connector. Common pitch sizes include:
- 0.8mm: Ideal for compact devices with limited space.
- 1.0mm to 1.5mm: Versatile options for a wide range of applications.
- 2.0mm to 3.96mm: Suitable for higher power requirements and larger devices.
2. Connector Models
Here are some popular connector models categorized by pitch size:
PH=0.8mm
- JST SUR Connector
- JST SUHR-02V-S-B
- Hirose DF52-2P-0.8C
PH=1.0mm
- Molex 5013300300 (Pin 1 on the right)
- JST SHR Series (With or without protrusions)
PH=1.25mm
- JST AGHR-03V-1 Series
- Molex 51146 Series
- Hirose DF13 Series (DF13-2S-1.25C, DF13-3S-1.25C)
PH=1.5mm
- JST ZHR-3 (Pin 1 on the right)
- Molex 87439 Series
- Molex 502578-3P (Pin 1 on the right)
PH=2.0mm and Above
- JST PHR Series (Pin 1 on the right)
- Molex 5264-N (Pin 1 on the left)
- JST VHR-2N (3.96mm pitch for high-power applications)
3. Pin Orientation
Pay attention to the orientation of Pin 1, as it determines the correct alignment for your circuit:
- Pin 1 on the right: Common in JST and Molex connectors.
- Pin 1 on the left: Found in models like Molex 51021 and JST XHR series.
4. Protrusions and Design
Some connectors feature protrusions for secure locking, while others have a flat design. Choose based on your device's mechanical requirements:
- With protrusions: JST SHR-**V-S-B.
- Without protrusions: JST SHR-**V-S.
5. Color Coding
Certain connectors come in different colors for easy identification:
- Black: JST SMP-**V-BC.
- White: JST SMP-**V-NC.
Why Choose the Right Connector?
- Safety: Ensures stable connections and prevents short circuits.
- Efficiency: Optimizes power delivery for your device.
- Durability: Reduces wear and tear over time.
- Compatibility: Guarantees seamless integration with your Li-Po battery and circuitry.
Final Tips
- Match the Pitch: Ensure the connector's pitch aligns with your PCB or device requirements.
- Check Pin Orientation: Verify Pin 1 placement to avoid reversed connections.
- Consider Locking Mechanisms: Protrusions or locks can enhance stability in high-vibration environments.
- Consult Manufacturer Specs: Always refer to datasheets for detailed dimensions and ratings.
By carefully evaluating these factors, you can select the perfect connector for your Li-Po battery, ensuring optimal performance and longevity for your application.
