This listing is for a pair of MR60 Connector(s), with end caps to cover the solder joint.
MR60 are 3 pole, polarised/keyed connectors the same size as XT60 which is a small connector commonly used in the RC world, especially aircraft, drones, quads and so forth for connecting the primary battery pack to the fun thing.
MR60 might be used for brushless DC motors (BLDC) to to ESC connection, or if you just needed to carry two voltages and a ground, or whatever else you can imagine.
General specifications of MR60 connectors are that they handle up to 60 Amps (peak, 30A continuous, according to datasheet) - but when buying components that comes from China, test in a controlled manner if you are pushing the limits.
My XT and MR type connectors are all stamped AMASS, but like everything from China who can really tell as to the authenticity.
All of our products are shipped from Christchurch, New Zealand using CourierPost for NZ, and Airmail for international.
