Battery Cable (XLR) pinout

[Will.D]

So I just got my package from ebikes.ca yesterday and I unfortunately found that my charger and battery have different connector types. I plan to solder a new connector onto the charger but before I did that I wanted to verify the pinout.

I have the pinout of the charger:
Pin 1 Positive
Pin 2 Negative, thermistor
Pin 3 NTC thermistor

Does anyone know the pinout that ebikes.ca uses on their XLR connectors? I've emailed them this question too but I want to get this done ASAP. Oh, in case it matters it's their 36V 8Ah NiCad, 5C Max Rate..Triangular Layout battery pack.

Use a volt-meter.

Cut the wires on the oddball connector, and use a volt meter to make sure + connects to + ( V batt ), and - connects to - ( ground ) when you solder on the matching XLR..

Don't depend on a circuit diagram ... actually check it.

TYVM! That's exactly what I was looking for.

I've been messing around with the 4 pin XLR used on the Bionx 36 volt lithium manganese battery pack and 42V/2A Elite 8204C charger. The charger connects only to pin 1 (+V) and pin 3 (-V). It won't turn on until it sees some voltage, 2 SLA's in series will do it, 1 won't. It turns off somewhere around 38 volts, or maybe on low current or both. The battery pack also puts out -V on pin 3, don't know what for. Pin 4 is a mystery. I'd like to charge with PV panels and don't know if three in series (possibly 60 volts) could damage the BMS when charging stops. Any suggestions? I could read a two-wire signal or sensor if the pack provides them. If it doesn't, then why use this bizarre XLR connector?
