Just received my Frey HT1000 on the slow train from China. All is good but it came with a 48v 5 amp charger for the 21amp battery.

To make it last a bit longer as I will never require fast charging, I was looking to get a smart charger like the one Luna sell to charge at 1-2amps.

However, my connector is not something I've seen before. Its 3 pin but smaller. The outside diameter is 9.5mm and inside is a flat area so it only goes in one way.

I assume the 3rd pin is for temperature, same as the XLR size 3 pin. Anyone seen or know what this is please, plus any adaptors out there?

Mini XLR perhaps, but still need some sort of adapter for 99% of chargers. Took a look inside the charger and the third pin wire is connected to the board, so looks like the battery may not charge without this sensor in the charger or it may charge and ignore temperature.
