LTC6811 balancing.

Category: Hardware
Product Number: LTC6811-1

Hi, I'm developing a BMS for a formula student team, consisting of 15 slaves in a daisy chain coonfiguration. My main concern is the control of the balancing, which is the most optimal way to do so? It's not clear to me if the balancing must be controlled by the controlling board with the mcu using the DCCx registers or if it is enough to set the overvoltage treshold(and maybe another settings, but it is done automaticly by the LTC itself). If it is the first case how do you select which board you want to balance in the daisy chain? I'd also like to know if any software configuration has to be made in case of using external mosfets for the balancing circuit. 
Thank you.
