there is a lot of corrsion/ green crustys on the negative battery cable you can see it on the battery terminal its the crimp thats the issue, hence the reason it was struggling there is a big voltage drop on the grounf side see the video you will see what i mean... good vid by the way keep them coming
Yeah I did check that with an amp clamp and there was no significant amp drop on the ground side, there was some corrosion on the positive bus bar on top of the batter that was causing the high resistance/current drain

What about BMS (Battery Management System)? If it needs it how do you do it?
You need a diagnostic scan tool with special functions, these are usually listed as ones that can do coding or bidirectional controls
