85v cut off for 74v 21700x20 battery pack?

[Sopheus]

Hello,

There is a pre-set 85v overcharge cut off limit on BMS for 20x pack of 21700 74v batteries, although I have read that maximum charge of 74v batteries should be 84v, not 85v. Should I leave the setting as is, on 85v, or it would be safer to reduce it by 1v to 84v?

Thank you

Found this (attachment), so it seems that every cell can be charged up to 4.3v, that gives 86v for 20 series pack, although drastically decrease battery lifespan.

Normally BMS should not have to shut off the charge cycle so the more important is the cutoff voltage of your charger. I would set BMS at max 4.2 per cell and charger at 4.15V
