I just made a 24v battery from 8 3v Lithium batteries. Charged each with adjustable power source to maybe 95%. Then top-balanced all 8 in series to 28.8v with the same 24v Victron charger you have. I will add a BMS to my battery to keep all 8 close, hopefully. The charger by itself appears unable to take the place of a BMS. Note I am NOT an expert in this area - still learning.
Nice, thanks for sharing. Yes, you will still need a BMS to balance the individual cells. The charger will just keep charging until the total voltage gets to the desired voltage. So if one of the cells gets damaged and doesn't hold a charge, it will over charge the other cells to get to the desired voltage. That's where the BMS comes in and keeps each cell at the max and min voltage to keep the entire pack balanced.
