regen voltage limit on infineon controller

Goodmorning at all of you here,
I want to ask you if there is a limit on the battery voltage that I plug on a infineon controller for the regen brake.
Can I have regen brake with a battery that it at least 20S?
And with a 24S?
Thank you.

Almost all of them I have seen are factory setup for much lower regen voltages as you have probably found. You don't say what battery chemistry you intend to use, but they can be modified with resistors to support 80v+ regen. It has been years since I have done it, so I can't remember what exactly needs to be done. I am sure you can find it through searching old threads on this board.

Goodmorning to everyone,
Thank ecycler I wanted just to know if I miss something, I'm not so able to open and elaborate the controller.
Thank you

Which controller do you have exactly? They are all similar, but there were a lot of variations over the years.
