Amass XT90-S Anti-Spark Power Connectors - Pair M/F

Amass XT90-S Anti-Spark Power Connectors - Pair M/F


In Stock


With the growing popularity of high voltage setups on R/C model helicopters, drones, EDFs and airplanes, sparking battery connections are increasingly becoming the biggest enemy to your electronics.

Now, we have just the solution. Made by AMASS, the XT-90S is based on the popular XT90, but now integrates an anti-spark system that helps to protect against current spikes and premature connector erosion that can lead to ESC failure. The design also provides no chance of incorrect polarity connection.

The XT90-S is 100% compatible with existing XT90 connectors. It also comes with a soldering covers that clip on each connector giving you a neatly wired plug and helps to prevent short circuits.

Choosing the right connector: There is a massive array of connectors on the market and they are not universally suitable for all multicopters. In basic terms, a connector is a device used to connect two or more electrical elements in order to allow current to flow from one to the other. In reality this could be achieved without a connector, so this correctly implies that there are other requirements. Technical requirements such as, current rating, resistance, and reliability should principally guide your choice; however personal preference based on ease of use/soldering, past experience and recommendations is usually the deciding factor. There are 2 main kinds of connectors, those that have the electrical contacts covered, or housed, and those that are exposed. Housed connectors include connectors like Deans and exposed are like bullets. While housed connectors are marginally heavier, they are safer as their shielding helps to prevent electrical shorts. Bare connectors can be made safer by applying heat shrink. Another advantage of housed connectors is that they typically prevent you mixing up the polarities and shorting the battery. Connector choice is most critical for high current applications, it's best to err on the side of caution when it comes to current rating. Always remember that there is no problem with using a larger connector than is required, apart from added weight and cost. Generally speaking small JST connectors are used to connect auxiliaries (BECs, LEDs etc), while 3.5mm bullets are often employed to connect ESCs to Motors. Finally, Deans, EC3s, XT60s, HXT 3.5mm are generally used for mid current applications, while 5.5mm bullets, EC5s and XT90s for high current applications.
