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 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. Transfer Multisort Elektronik sp. z o.o., ul. Ustronna 41, 93-350 Łódź hereby informs you that it will be the controller of your personal data. 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
As a general guideline, I personally follow this table based on the burst current requirement (e.g. current draw at full throttle): Your personal data will be stored until you withdraw your consent to the processing of your personal data. Made from high-temp Nylon and gold plated spring connectors, both are included in the same injection mold at the time when forming the connector. The XT30 ensures a solid high-amp connection, perfect for applications up to and beyond 35A constant.
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. 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. 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.
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: While it’s tempting to overcompensate and use larger connectors, it’s not always necessary and can add unnecessary weight to your drone. In some cases, it may even have a negative impact on your drone’s performance. For example, when it comes to micro drones such as Tiny Whoops, there’s a debate about whether XT30 connectors or BT2.0 / A30 connectors are the better option. While XT30 connectors have a lower resistance than PH2.0, BT2.0 and A30, but the benefits are hardly noticeable while it’s much heavier, some argue that BT2.0 and A30 are the optimal choices because they provide a good compromise between weight and performance. You can learn more about these connectors for micro drones in my testing: https://oscarliang.com/micro-battery-connectors-testing/ 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.
One important factor to consider when choosing wires for your FPV drone is the wire’s resistance. Longer or thinner wires will have more resistance, which can lead to voltage drop and power loss (especially so for the battery). This is why wires have a current rating. However, recent test has shown that the XT30 connector can actually support a much higher continuous current of up to 60 amps without any problems, as long as the wires connected to it are large enough. This means that you can safely use an XT30 connector for applications that require higher currents, as long as you follow the appropriate safety precautions. Both connectors have a commendable lifespan, enduring over 1000+ cycles. However, in terms of temperature resistance, Deans slightly outdoes XT30, withstanding temperatures ranging from -20°C to 150°C, compared to XT30’s -20°C to 120°C. Conclusion 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.
