Where to find information about the 18v output on the Bosch GAL 3680CV charger?

Hi. I would like to look at the charge profile for the 18V option on this charger. If at all possible I would like to charge my made-up 18v Liion batteries (using 4x2x18650 cells) which don't have a BMS - instead I monitor the individual 2-paired-cell voltages, both for charging and discharging. Thanks Peter
