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. 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 BT2.0 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 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. 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)

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.Application: for signals, power for your FPV system, receiver etc, basically anything that isn’t battery or motor related.

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: As a general guideline, I personally follow this table based on the burst current requirement (e.g. current draw at full throttle): 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. There are several types of wires available, the most common type used in FPV drones is silicone stranded wire. Compared to solid core wires, stranded wires are more flexible and easier to work with.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. 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.

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. Deans: While it offers excellent performance, some users might find XT series connectors easier to handle, both in terms of soldering and plug-in/plug-out operations. Electrical Properties Connector (Plug) XT30, Designed by hexTronik to be more reliable and a better quality connection than Mini Deans T-Connectors and Mini JST for the given size and weight.

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 Electrical properties: Silicone wire has high voltage resistance and can reach tens of thousands of volts. PVC wire is generally only a few hundred volts. The current performance is the same for both and is generally determined by the internal conductor. 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. 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. 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.

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.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. 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. In general, the higher the AWG number, the thinner the wire. The lower the AWG number, the bigger the cable size and current capacity. The current rating of a wire is the maximum amount of current that it can safely handle without overheating or becoming damaged.
