It makes any sense have an isolator after a single output from a Victron IP22 12V 20 (3)?

My boat had installed an old battery charger with 3 outputs but was only using one of them connected to an isolator, which was feeding 3 lead-acid batteries 120 Ah. The battery charger collapsed and I substituted by a IP22 12 V 20(3) Victron charger. There is any reason that I should keep this type of connection or should I eliminate the isolator and use the 3 output to charge individually each battery?

Thank you

You should have a battery isolator in the circuit. Assuming the three batteries are wired in parallel as a single 12V system, connect one of the outputs from the charger to the non-battery isolator side. Don't use the others. You'll get full output down a single connection.
