Description -
With the growing popularity of high voltage setups on R/C model helicopters, EDFs and airplanes,
sparking battery connections are increasingly becoming the biggest enemy to your electronics.
All the anti-spark systems in the market today require some sort of modification or DIY work before use.
Now, we have just the solution. XT-90S is based on the popular XT90 but now integrates an anti-spark system. With the XT90-S, no need to invest to a secondary anti-spark system (which provides an additional failure point to your system).
100% compatible with existing XT90.
Comes with a soldering cover to protect the solder point.
Spec.
Weight: 15.3g(Each Pair)
Size: 49x21x10mm(Each Pair)IMPORTANT: "These are not cheap copied XT90 plugs. These original Nylon XT90 plugs, manufactured by AMASS, can handle over 90A current for extended periods without exceeding 80DegC thanks to their better contact surface area. The plug is also less likely to deform or melt in comparison to copied non-Nylon XT90 plugs."

There is a slight issue when plugging and unplugging under load say from a charger and that is that the contact get broken as it slides in and out past the resistor connected contact and the direct contact. This results in a momentary loss of power and then it comes back on again. So I would recommend inserting and removing more quickly. I also found them very hard to disconnect with one male connector I use. Also using banana plugs into the female connector is probably not going to work well because the plug will not make contact with the inner direct connection, it only makes contact with the resistive outer band contact. I use DC chargers with XT90 battery packs and plug the banana power plugs from the charger directly into the XT90 connector. Still a great idea though!For years I have had to "pre-charge" my big controllers with either a resistor or my favorite ... A lightbulb or two in Series... to limit the rush of current into the input filter caps of my controllers. These female connectors have an additional ring contact at the beginning of the positive hole that connects to a 5.6 ohm internal resistor to the rest of the positive contact further in the hole. This effectively and simply limits that charge surge to about 10 amps for a 50 volt pack, 5 amps for a 25 volt pack. Ok so you need to change a connector on your single battery or on the 2 into 1 wire harness, not a big deal or you could just take the male and female connectors and solder them back to back and plug that in line if space and weight is not an issue like with your charger. Yeah there are capacitors on both input and output of chargers. Don't plug them in too fast and you might be able to prevent a reverse polarity blunder like I pulled with a 3s4ah graphene battery ... Blew the solder off the shunt in a 180 amp watt meter!I have been a big fan of the XT60 connectors and have used them for many years but with my use of ever more powerful LiPo cells, motors and speed controllers the larger XT90 plug is every bit as good and is more suitable for use with them.
This anti-spark version of the XT90 is a welcome development that prevents sparking and can be highly recommended.These are obviously more expensive than regular XT90, but sparks are 1/ unpleasant 2/ scare anyone that's around 3/ could damage the electronic. Buy these just for peace of mind they do work and the quality is slightly above regular XT90 as the package includes protective covers that make shrink-tube unnecessary.These are a must to prevent pitting in the connection, which happens when you hear the "pop" noise.Fantastic product, absolutely no sparks when plugging my 6S lipos. Soldering cover is simply perfect and eliminates the need of heat shrink tubing.
I wish the anti-spark device was installed on the male connector (ESC side) as this would require soldering just one connector (instead of one for each battery).No sparks anymore!!! great connectors. A little bit heavy. I use this in connection with 8S lipos. I will buy further one when they are in stock again. I hope they will do their job for a long time.Please include technical information and any useful data which may help other customers.Working just fine for me so far using them with Turnigy 5000mAh 45c lipos. Just make sure to get the wire touching a lot of contact surface when soldering as a poor job will cause too much heating up on too small of an area causing it to melt the plasticGreat connectors for high current! I am use them for 80a motor -
