18Ah of discharge and in C20 capacity, I had inquired and C20 is the autonomy in hours ...
like I said 18Ah for 20h that's a lot

18Ah is already a capacity that takes into account the hours, you cannot provide 18Ah for 20h, that does not mean anything.
With an 18Ah battery you can provide 1A of current for 18H or 18A for 1H.

good first part of answer from matt113
I complete because it would be too good if the same battery could provide:
i.e. 18A for 1 hour
i.e. 1A for 18 hour
in fact the capacity of a battery decreases according to the current which one draws, this is why the manufacturer indicates on which duration is measured the capacity
in this case your 18Ah battery at C20 will give 0.9A for 20h which makes 18Ah
on the other hand if you draw 18A, there is a good chance that it will only deliver it over 30 or 40 minutes whereas in theory, it should do it over 1 hour (18Ah)

our friend has a motor that consumes 36A peak
let's say that it will light a little thus a current between 20 and 30A permanently. you should not expect an autonomy of more than 30 minutes. it will also depend on the minimum voltage value at which the controller will cut to protect the batteries. in general, for a 2x12V battery, avoid dropping below 22V
