The 4-pin XLR has two pins soldered to each wire. I forget which is which but the 4-pin XLR plug on the end of the charger unscrews easily to determine this. If you buy a Luna charger for example, it'll have an XT60 plug coming out of its charger. You'd need to make an XT60 to 4-pin XLR adapter.
However, I tried to do this recently and failed miserably. I suck at soldering and have a crappy soldering iron. But there's an easier solution... See if you can get Juiced to give/sell you a second 5.5mm-to-4-pin XLR adapter (this is what they actually ship with their stock chargers - not sure what they ship with the Satiator chargers). Reason I say that is that it's easy to get for instance an XT60-to-5.5mm adapter from Luna. Then you don't have to make anything - just go from the Luna XT60 to 5.5mm barrel using their adapter, and then from the 5.5mm adapter to the 4-pin XLR with the Juiced adapter. This is working great for me with my Luna charger.
The wildcard here is if you can get a second adapter from Juiced. I didn't need it because I only charge at home. They're listed as sold out on the website.
