Why do you want to measure the voltage? - it's whatever the batteries need at the specific time.

Generally, chargers usually use constant current, and then switch to constant voltage and start dropping the current - dependng on battery type.

The battery charger cutt off when battery voltage reaches 61v
Anyone know how to check the voltage ( to confirm battery voltage is 71.4)

You simply stick the meter across the battery - if it's reading 10V lower than it should, either the battery or the charger is duff.
