Freedom Coast levers for Magura MT5 (did I get the wrong variant?)

So, I bought custom Magura levers and didnt notice that there's a BAT (MT7) and non-BAT (MT5) variants. I got the BAT variant and installed it on my MT5 (which shouldn't be compatible?). Somehow it works, but I still feel that I got the wrong one

The variants arent interchangeable, right? The internal pin (not shown) is different?

I contacted FC and am awaiting their response
