It is. It's the Neutrik brand XLR 3-pin connector.RTIII said:(Looks to me it's the exact same jack as is used for microphones in the USA - and other "professional" music connections for a sound stage.)
There's a lot of other possible connectors they could have used, but there are actually a fair number of existing bikes and batteries that have used XLRs as the input (I have an old Crystalyte NiCd pack, for instance, though it's dead).
It's pretty durable, and it can handle current up to the level the Satiator can output, and is designed to deal with 48v phantom power for mics and such.
That can be true, for the reasons you've stated (that I didn't quote), and others.The problem is that they put this intermediate jack way out on the end of a fairly long lead so that the adapter lead you then connect to it is fairly short - WRONG WAY AROUND, if you ask me!
Personally, I just use a panel mount XLR on the bike itself for charging with the Satiator. It's one from Grin, and comes with a water-resistant cover. This is it under the battery cutoff switch (which has since been moved, but the XLR is still there).
Before mounting it
The Satiatior is also designed to bolt directly to the bike or vehicle if you only use it on one; it's vibration and weather resistant, and then can be wired straight in if you like. Until I got the HLG meanwells I was going to do that on the trike, with a switch on the output to toggle it between the lighting pack and the traction pack, leaving it where I could see the screen and push the buttons to switch between the two voltage pack profiles.
