FREQUENTLY ASKED QUESTIONS (FAQ)

1. Which housing is considered the "male" side? In the JST RC series, the housing that fits inside the other is the male, while the slightly larger one that receives it is the female.

2. Do I need a special tool to install the pins? Yes, a dedicated crimping tool (such as an SN-01BM) is required to properly secure the metal pins to your wires.

3. Can I solder the pins instead of crimping? While soldering is possible, it is not recommended as it can make the wire brittle and prevent the pin from clicking properly into the housing.

4. What wire size should I use? These are optimized for flexible silicone or PVC wire between 20 AWG and 24 AWG.

5. Is this compatible with 3.7V batteries? Yes, this is the most common connector used for single-cell (1S) LiPo batteries.

6. Does it prevent the battery from being plugged in backwards? Yes, the housing shape is keyed so it can only be inserted in the correct orientation, protecting your electronics from reverse polarity.

7. What is the maximum current these can handle? They are typically rated for up to 3 Amps of continuous current.

8. How do the pins lock into the housing? The pins have a small metal tab that snaps into a slot inside the plastic housing once fully inserted.

9. Can I remove the pins once they are inserted? Yes, you can usually depin them by using a very small needle or tool to press down the locking tab through the housing slot.

10. Why are they red? Red is the standard color for the JST RC series, helping to differentiate them from other connector types like the JST-XH or PH series.

11. Are these waterproof? No, these are standard open connectors and should not be exposed to water without additional protection.

12. Are the male and female pins different? Yes, the kit includes specific male and female metal terminals to match their respective housings.

13. Is the pitch 2.5mm or 2.54mm? The standard JST RC series uses a 2.5mm pitch.

14. How many wires does it hold? This is a 2-pin version, ideal for positive and negative power lines.

15. Can I use these for high-speed data? They are primarily designed for power delivery, though they can be used for low-speed signals if shielded wire is not required.

16. Will these work with JST-PH or JST-XH headers? No, those are different series with different pin spacings and housing shapes.

17. What happens if I use too thick a wire? The pin will not crimp properly, and the assembly will not fit into the plastic housing.

18. Is this suitable for micro-drones? Yes, it is a very common battery and power connector for micro and mini RC aircraft.

19. Does the kit include wires? No, this is a hardware kit containing the housings and pins only; wires must be supplied by the user.

20. Is this suitable for beginners? Yes; while crimping requires a specific tool, it is a fundamental skill for anyone getting started in robotics or RC.
