3 PIN XLR to DC Controller

[egk]

I have a lithium battery connected up to a DC motor controller and I'm trying to figure out how to recharge it. The DC motor controller comes with no documentation, but using similar docs from others, I think the red plug (I think they are called JST plugs?) allows you to recharge the battery via the DC motor controller rather than having to disconnect the battery each time.

Along with the battery, I was given a wall charger that has a 3 PIN XLR connector.

How do I connect this up? Am I right in all that I have to do is find or make my own XLR to JST connector and just connect it direct to the DC controller ignoring the third pin? Is there a name for this 'connector'?

I have three batteries that I use XLR ports with. I use Grin Cycle Satiators and XLR is the default. Two of the ports, I got from Amazon (https://www.amazon.com/gp/product/B00OVAWS7I). I just wired the port directly to the battery each time. A fuse wouldn't be a bad idea for safety, though your charging wire will act as a fuse if things go badly if you're into that. Yes, you can ignore the "third" pin.
