Settings to balance batteries

We have had a whole new system installed in our sailing catamaran in Mackay, Queensland.

We have

VE.Bus BMS V2

MultiPlus-ll 12V/3000VA/120AMP PN PMP122305010 SN HQ230963VEH

Cerbo GX

GX Touch 50

Four LiFePO4 Batteries Smart 330AH/12.8V

Smart Shunt 500A/50mV PN SHU050150050. SN HQ2301R3QT7

Two DC/DC chargers for the motor alternators

Two Solar Controllers for the solar panels

Shore power

Attached is a photo of the system.set-up.jpg

The batteries have been imbalanced since they were delivered and installed. devices-2.jpg

Can you clarify for us the parameters that should be set for charging the batteries through the smart charger for normal operation and for balancing?

We purchased a Victron Blue Smart IP65 Battery charger SN HQ2249J6QW2 can we use it to balance them or do we need a one with VE communication.

Thanks

Yes you can use the charger.

New batteries can take some time to balance, it's normal. Ideally they'd be fully charged/balanced before installation.
