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.
Connectors are an essential component for attaching two components temporally, such as the battery and ESC. You can also use connectors if you don’t like soldering. Here’re are the weights of the LiPo connectors I tested, which includes both the male and female connectors. All measurements were taken using a cheap priced digital scale, with an accuracy of 0.1g.Answer: No, it’s not advisable. Pulling the connector by the wire can stress the connection point, potentially leading to wire breakage or damage to the connector itself. This can cause the connector to fail prematurely or even create a potential hazard. It’s always best to grip the connector’s body when plugging or unplugging, ensuring that the force applied is directly on the connector and not on the wire. I measured the connector resistance at 0.90 mOhms and 1.22 mOhms for the 2 pins. The XT60 had 0.70mOhms both. The jst connector I measured had 22mOhms and 18.
The primary performance metric we’ll be comparing is voltage sag. A connector with a higher resistance will display a higher voltage sag, which is indicative of subpar performance. It will also reach the minimal voltage early before completely discharging its capacity, resulting in less flight time. Final Verdict 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.Your personal data will be stored until you withdraw your consent to the processing of your personal data.
Deans vs XT60: The Battle of the Connectors FAQs of XT30 and Deans Connector Q: Is the plug getting hot due to excessive current?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.
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? You have the right to access your personal data and request it to be corrected, deleted, or limit its processing;

I agree as well... for anything 100-200 grams or so with 7-20A draw, they are the only choice. I started with them on my Tarot TL130; they turned a floaty, poky little porker into a tight little beast. 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. 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. 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 If you don’t have any spare, these connectors are cheaply and widely available. Select balance lead based on the LiPo cell count, and use XT30 or XT60 depending on what’s on the parallel charging board.
