E bike controller identification

[Erikjan]

I have a 24 fet controller and am looking for some info. Do somebody regonize this controller board?

I am looking for the info about the codes at the pcb for cruise speed limit and the rest.

There are codes A1-A4, E1-E5, C1-C3, sl, sh, sx x, x, zf, q, L.

It have 75V fets P75NF758 and 63V capacitors. I like to replace the capacitors for 100V. And use a 16s battery.

Why not replace with a controller that meets your criteria? They're not as expensive as retrofitting one, only to smoke it anyway because you overlooked something.

Thats an option, but this is also for fun i have more controllers.

I find some things already.
