Lithium battery initial charge using Smart Solar Controller

I have (4) 12V lithium batteries that I am about to set up in series to get a 48V bank. The manufacturer recommends initially charging each battery to the same voltage (14V) before wiring them together in series. Can I use my Victron Smart Solar MPPT 150V 60A to charge each battery initially before I wire them together in series? Or, am I going to have to buy a battery charger to do this initial charge?

It should work. Maybe charge the batteries in parallel.

Perhaps another option is to use my Quattro to do the initial charge on each battery. Thoughts?

Unlike the solar charger, which can use several battery voltages, the inverters are made for a single voltage (a single nominal voltage).

So you can't use a 48V inverter/charger to charge 12V batteries.

Ah! Good point. Thanks.
