The converter works up to 300v or a little more, how to make it work at 400v. for gen 3, the divisors simply change, but for 2, what should be changed? I didn't find any relevant information, maybe I missed it. Thanks in advance for your help.

Something I’ll be looking at again soon as I’m increasing battery voltage and the gen2 Dc-dc shuts off at about 330v I did once identify 2 resistor networks from the input that I believe to be the voltage sensing, have misplaced the pictures though so need to start again.

Can you use the buck boost to buck down the 400v to 200v?

Yes that’s another way to do it, I believe Johannes did that with the Audi…

Hello, can you be more specific which resistor chains have been changed.
