The mini XLR connector is relatively new for 48V battery, you can't use the 48V charger in a 36V battery. There are adapters for the new 48V charger to be used with old 48V batteries with jack socket but we won't sell you the adapter unless we know exactly why you need it.
The new connector is not as good as an intelligent CAN-bus charger but it makes mistakes far less likely.
