Based on the Chinenglish on the reply it looks like TechDirect is a direct Chinese reseller.
Those BMS are designed for toys like e-bikes and scooters, so You will need to make some changes to make it work on a Golf Cart.
Since the BMS can handle the charging current, leave that part alone, meaning the Anderson connector will only be used for the charger connection.
Run new 4ga or 2ga cables for the pack positive and negative directly to the Solenoid B+ and to the Controller B-.
Get a 48v relay coil like the one below to provide the LV cutoff for the cart power.

Disconnect the wire that goes to the "cold side" of the key switch (the side that only has power when the switch is ON).
Connect that wire you disconnected to the "COM" terminal of the relay.
Run a new wire from the key switch "cold side" to the relay "NO" terminal and to one side of the relay coil.
Connect the other side of the relay coil to the negative coming off the Anderson connector.
Install a diode in parallel with the relay coil, the side with the stripe goes on the same side as the wire from the key switch.
That will allow the BMS to still provide cell level LV and HV cutoff, but instead of cutting the entire current path OFF to the cart, it will only prevent the controller from operating in case of an LV condition.
It will also eliminate your shutdown due to excessive current unless that current causes the pack to drop below a safe level.
Edit: I just noticed that there are no bus-bars in that design, just the circuit board copper traces to carry the cart current.
Unless they are using pretty hefty 6oz+ copper traces, that does not seem safe to carry much current.
