Hv battery connector splitter?

So I was wondering if there was an adapter that would split the power from the battery to the car so I could add a second battery without putting it on a lift and dropping the pack.

I went in through the PDM cover, connected onto the vehicle side of the bus bars that are bolted to the fast charge contactors, and used cable glands to seal the entry points (in the cover above the heat pump cable entry point). This ensures excellent electrical connections (poor connections will cause insulation failure fault codes)

The inside "roof" of the PDM cover needed the ribbing removed above the bolts and cable lugs to get good clearance (about 7mm clearance)
