Hi
If I would like to use this IC to charge 20 x Lithium Ion Cells in series ,could i simply change the FB resistors and have and
additional LDO on VAC ?
Kind regards!

Hello Sarel,
The max charge voltage of the BQ25750 is 70V or about 16S. When charging at high voltages, we recommend a diode or snubber to protect the IC from transients for battery hot plugs.
