I had no problems soldering and insulating the connectors, and at the field they are easy to pull apart, especially after using JST for so long. Answer: Yes, that’s one possible reason. Overcurrent can cause connectors to overheat because as current flows through the connector, resistance can generate heat. However, another reason might be a poor solder joint, sometimes referred to as a “cold solder joint”. This can create additional resistance and localized heating. Q: How can the durability of connectors be improved?

While the XT60, a member of the XT series, is widely regarded as a technologically advanced successor to the Deans, it’s crucial to note that many RC manufacturers still prefer the Deans due to its cost-effectiveness. This affordability makes the Deans plug a preferred choice for many, despite the rising popularity of the XT60 in various RC models and chargers. Usability Deans: Medium-sized. Perfect for larger RC cars (1/8, 1/10 scale), boats, drones, and RC planes with a wingspan over 1m. Best paired with 3S, 4S, and 6S LiPo batteries with capacities over 1500mAh. Durability & Lifespan

There is no patent on the XT30 connector, we hope this product is sold everywhere in the world and dominates the market, reducing customer dependency on the over-priced and underperforming alternatives for this amp class.

When extending a capacitor in your FPV drone, the recommended wire gauge will depend on the size of the capacitor and the amount of current it will be handling. But in general, the length of the wires are more important than the wire gauge. It’s important to use the appropriate wire size to minimize voltage drop and power loss due to resistance, and to reduce the risk of overheating. However, in some cases, it may be acceptable to use slightly thinner wires if the wire length is short and the current bursts are only for a short period of time to minimize weight. There’s also voltage rating for electrical wires, but it’s usually not a concern for RC applications, since the voltage we are dealing with are well below 30V. The wires we use can tolerate much higher voltage (e.g. hundreds of volts or even higher). Where to Buy Silicon Electrical Wires My power distribution board had 3.5mm connectors but changed them to 5.5mm Castle Creation connectors. Because of that I replaced also the bullet connectors from the ESCs end side to 4mm. I also upgraded the wire to 10AWG but even after doing all that I’m still having the same issue. Now the only connectors I haven’t replaced yet are the motor bullet plugs from the motors, as well as the connectors on the speed controllers to the motor side which are 3.5mm. Answer: Avoid overheating. If your connector is getting hot, it is an indicator that there might be too much current flowing through it for its design specifications. Over time, excessive heat can degrade the materials and performance of the connector. To ensure longevity, you should consider replacing it with one that is rated for a higher current capacity. It’s also crucial to ensure proper installation and secure connections to reduce the likelihood of issues like cold solder joints. Q: Is it correct to pull the connector by the wire when disconnecting it?

Physical properties: In terms of softness, the silicone wire is relatively soft. And PVC is relatively hard. At low temperatures, PVC wire is softer than silicone wire. During the test, the battery was discharged at a constant current of 12A, until the voltage dropped to 6V (3.0V per cell). This 12A load is a reasonable representation of the demands placed on a 1S or 2S micro quad. A typical tiny whoop draws fewer amps than this. Here I made three adapters for 2S, 3S (XT30) and 4S (XT60). You can remove the wires in the middle, all you need are the two wires on the outside (first and last wires). Solder these two wires to the XT30/XT60 connector, Positive to Positive, Negative to Negative. Finally, to help prevent damage to your battery lead solder joints during crashes, it’s recommended to secure the battery lead to the frame using zip ties. This provides stress relief and prevents pulling the solder joints during a crash. More Info and Discussion The heat dissipation performance of the multi-strand wire is better than that of the single-strand wire because the multi-strand wire has a certain gap.

In my 6S 5″ builds, I usually use 14 AWG wires for connecting the battery, even though the maximum current draw might be slightly over the current rating of the 14AWG wire. I don’t think this would be a problem because, firstly the wires are quite short; secondly, the current bursts typically only lasts for a couple of seconds, even if you leave it at full throttle for longer, the battery wouldn’t be able to keep up anyway. The main reason I prefer 14AWG over 12AWG is because they are easier to solder to the ESC, and can shave a couple of grams off my build. The GNB27 displayed similar performance to the BT2.0 and A30 in our testing, and it’s slightly heavier, so it makes more sense to use BT2.0 or A30 for tiny whoops and other 1S micros. Additionally, in my experience, the GNB27 connector is a bit harder to use than BT2.0, as it’s really tough to pull apart when swapping batteries. A30 and BT2.0When connecting two wires, the maximum current that can be passed through them is limited by the smaller wire. Therefore, if you are extending a wire, it’s best to match the wire gauge and use the same AWG wire. Using larger wires than necessary doesn’t provide any benefit but extra weight, which is not ideal for an aircraft. This is why it is important to use the proper connectors and wire gauges. (Tips: Obtaining the proper wire gauge and connectors can extend the life of the device.) XT30: Small-sized. Ideal for small drones, RC cars (1/16, 1/14 scale), RC planes under 1m wingspan, and 250-size quadcopters. Most suitable for 2S and 3S LiPo batteries with capacities below 1500mAh. On the other hand, the XT60 connector has also been put to the test, and it has been found that it can safely handle burst currents of up to 180 amps for 10 seconds without any problems. This makes it a reliable choice for a typical FPV drones without the need to upgrade to heavier and bulkier connectors. XT60 Connectors

It’s also important to avoid resting cables on top of the flight controller, apart from potentially causing interference, it could also be hitting the gyro which affect flight performance. Instead, try to route cables underneath or around the FC. Using the adapter, basically you are “cheating” the charger that the two outer wires in the balance lead are the discharge lead. (in fact these two wires are connected to the same solder joints inside the battery as the discharge lead, you can confirm with a multimeter in continuity mode) Application: for XT30 on sub250 builds, and motor wire extension for 5″ builds. 18AWG also works well if you don’t mind the slight extra weight. When connecting wires and components, ensure that they are securely fastened and will not come loose during flight. Loose wires can cause significant damage to your drone during flight and potentially lead to a crash. When building an FPV drone, minimizing weight is important. For instance, here are some commonly used wire gauges for different components on a 6S 5-inch FPV drone:

To maintain consistency throughout the testing, I chose to use the same battery for all the connectors (a 2S 300mAh LiHV battery). The original connector on this battery was replaced with the connectors under test. Products that weigh more than 0.5 KG may cost more than what's shown (for example, test equipment, machines, >500mL liquids, etc). I used the SkyRC D200Neo charger and the BD350 Battery Analyzer for this testing, which allows me to log data and plot graphs. However the BD350 only works on a minimum of a 2S battery, that’s why you are going to see the test were done with 2S LiPo and not 1S.
