OK, the good news is that both brands listed are designed to allow series/parallel wiring, and both have a 200A BMS. The bad news is I have no clue whether or not the two different brands are OK to wire together.
To start out, and just get the system up and running, I would suggest you wire only four of the Talentcell batteries in series to get one 48V string. Then communicate with both manufacturers and ask them to state whether these two brands can be mixed.
To get started, I'd suggest setting your bulk and absorb charge settings to 58.4V, with the potential to raise the voltage to 59.6V is it is deemed necessary. If setting the float voltage is required, I'd start at 55.2V.
How did you end up with two different brands to begin with? I don't have much experience with Li, so I'm not going to tell you it's OK. Best for you to ask the manufacturer. Maybe Will can chime in here?
