If you have never done this yourself, a local dealer might be a better bet for help when things stop working. They would have service techs familiar with the system who could help. Might be able to do warranty work without shipping things away yourself.
Also, BMS need a computer to program it. Keep that in mind because if on your own you need a PC, an interface box or cable, plus the software. That's great to have, but might have a cost.
There are a number of FB groups with people doing the same thing you want to try. Also see TY videos.

You are correct in my experience. The "Controller" is an entirely different device. The previous post is like saying you can't use a different kind of battery in your hearing aid or flashlight. The Controller has no clue how your battery is producing power, only that the power is sufficient/compatible. The Battery Management capability is in the charger, not the cart.
