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.
The batteries have been imbalanced since they were delivered and installed. 
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
