BMV will treat the batteries as a single bank.

But what do you mean by 3 bank charger? Usual way on systems is to have batteries in series with charge from the ends. Here at 36V.

Marine applications commonly charge series 12V individually:


https://www.batterystuff.com/battery-chargers/marine-smart-chargers/promariner-protournament360-elite-series3-36-amp-4-bank-marine-charger-53364.html


The charger features four 12v outputs that can be utilized for multiple 12-volt batteriers configured in 12v, 24v, 36v, or 48v battery banks. Each bank outputs 12 volts for individual 12v batteries no larger than a group 31 battery (approximately 130 AH). The charger can sense and distribute the 36 amps between the banks, allowing up to 18 amps to be distributed to a single bank if needed.
