What is the Giant 3-pin XLR pin layout for charger?

I'm a dummy and left my backpack/charger on a trail and now don't have a charger for my Explore. Wanted to use my bench power supply to do battery charging since it has plenty of adjustable of volts/amps, but not sure what the pins of the 3-pin XLR should be. I figured one each for negative/positive but wasn't sure if the 3rd had any signal. I put a meter onto the battery, but not getting any readings on the xlr plug.

Anyone know the pin layout for this 3-pin xlr?

I've heard it's same as a regular microphone jack.

Tried wiring up an XLR connector negative/positive similar to the grin satiator but plugging it into the battery it doesn't register. I think a signal needs to be applied to wake the battery up, but not sure what to do and don't want to fry the battery. Hoping someone knows.

Turns out Giant wanted to be cheeky to probably try and sell more of their 'proprietary' chargers. They swapped the negative from pin 2 to pin 3. Everything working with pin 1: positive+, pin 2: empty, pin 3: negative-. Hopefully helps a future internet traveler.
