It is an IEC connector. https://www.newark.com/schurter/4301-0502/conn-fused-power-entry-module/dp/84K0270 Here is the whole category of 50 pages of them https://www.newark.com/c/connectors/power-entry-connectors/power-entry-connectors You can buy chargers with the mate to this on them about as cheap as newark sells new ones without wires.If you need the female, you probably have a dozen of them in the junk drawer for dead electronic devices like PC's. Cutting the NEMA 15A plug off and butt splicing a XT60 on would be what I would do. Good luck on finding an adapter. Competent butt splices are sold by Dorman at the auto supply, but use the red ones for 18 ga wire used on old PC's. Your battery connections really need 12 ga wire which is yellow, but finding a 12 ga IEC cord is as rare as those $20 Shurter power entry connectors on the newark link. One 12 ga one comes with each $1200 Peavey 1300 watt PA amplifier, and the only place I've found that sells the 12 ga ones is Peavey parts service.Note Newark minimum freight is $10 unless you specify USPS and orders below a certain dollar amount incur a handling fee. I'm always above $50 orders so I never get one.BTW I find all crimp connections not made with an Ideal Bulldog or Klein tool are ****. There are 99,999 other brands out there that produce garbage crimps. Making a good crimp is important at 30 amps. Also, acceptable brands of crimp connectors are TE connectivity, Panduit, T&B, Ideal, 3M & Dorman. "Just as gooe" crimp terminals sold on ali/ebay/amazon/radioshack melt out at 30 amps.IEC connectors are registered worldwide with UL, VDE, CE, etc etc as AC power entry devices for multi-voltage appliances. ie 120 vac/240 vac appliances. As they are used on e-bikes for 48 vdc or 36 vdc they are probably in violation of those registrations, and probably no ebike that uses one for the battery would have a UL VDE or CE rating. But they are cheap, and common.

Most of the time you're going to want to use an XT connector and most of the time you use an XT connector you're going to want to use an XT60 connector. XT60 connectors are small enough to fit just about anywhere but they are large enough to handle a tremendous amount of power. For example, it can handle 60 amps.
Well if you're sending 72 volts down a line at 60 amps, that's 4,320 watts of power. That's an insane amount of power. Really, that is a ridiculously substantial amount of power. And while it is true that an XT60 connector can technically handle that much power, realistically anything over 30 amps you want to use an XT90 connector because remember, connectors, wires, conductors, fittings, all that, they are rated based on their temperature. Also, XT90 connectors offer pre-charge circuits also known as anti-spark connections which is a nice feature.
The ratings are all about safety and not so much about performance. They just want to make sure your connector or wire or whatever doesn't burst into flames. So, that means that the top rating they give you is how many amps you can put through that connector, wire, or fitting before it gets so hot that it catches on fire.
That's not necessarily the point that you want to be running things though because a lot of voltage drop and performance loss will be generated if you run at the limits like that. Ideally, you want to run at half the limit when it comes to wires and connectors. You want to leave yourself 100% headroom on the temperature, that way you've got more than enough headroom on the voltage drop and performance characteristics.
Battery connectors are essential components that ensure the safe and efficient transfer of power in a wide range of battery-powered devices. Understanding the characteristics and applications of these connectors will help you make informed decisions when working on your projects or selecting devices.
