Hopefully, yours is a diesel with M51 BMW lump.
Setting up 2 genuine alternators means 220 A max.
Would you care to show some pictures on how did you attach the second one to the engine & the belt arrangement please?

Nothing stopping you from fitting it on the back in a custom bumper.

If I'm going anywhere slippy I engage difflock and let the mud terrains take me where I want to go.

Now airlockers would be nice.

It goes in place of your air conditioning pump and uses that belt and tensioner arrangement.

If you wish to keep your AC then you need to get creative about how you mount it and where you can fit a dual pulley for a serp belt.

Mine is for a 200Tdi which is a whole different ball game as it's old fashioned and runs V belts, whole new crank pulley, alternator mount, idler pulley and coolant hose guard need to be fabricated for it to work.
