Question: Is a JST connector safe for 3S packs on small RC planes?
Answer: JST connectors, commonly the JST-SM or JST-PH types, are generally designed for low-current applications. For a 3S LiPo pack, which typically delivers around 11.1V and can draw higher currents depending on your motor and ESC, standard JST connectors may not be the safest choice. They usually handle currents up to about 3-5 amps, so if your setup draws more than that, the connector could overheat or cause voltage drops.
For small RC planes with low power demands (under 5A), a JST connector might be acceptable, but it’s best to check your current draw first. If your motor or ESC requires higher current, consider using connectors rated for higher loads, such as XT30 or Deans (T-plug).
Step-by-step advice:
1. Measure or estimate your maximum current draw.
2. Check the current rating of your JST connector (usually printed or found online).
3. If the current exceeds the rating, upgrade to a higher-rated connector.
4. Ensure all connectors are soldered securely and insulated properly.
5. Test the setup under load and monitor for heat.
Using the correct connector improves safety and reliability in your RC plane.
