One thing I like to do when crimping high current cable lugs is to order extra and to a test crimp on a piece of wire. Then saw through the connector at the middle of the crimp. It should look like one nice solid piece of copper. If there are any voids then it means it's a bad crimp and/or mismatched wire/lug sizes. I once saw this done on a gigantic 500mcm cable that had the wrong size lug, the electrician told me it was NFG and you could see some gaps around the edges.
Assuming you have the two packs at the same voltage before connecting them and ensure they are both fused at the packs this should be OK. For extra safety you could put a contactor on each positive cable before it leaves the pack but could this see one pack voltage drifting away from the other if the car was not used for an extended period? Probably not but worth checking into. The inverter is controlling the current, not the battery packs so the Sbox will be OK so long as you keep the current draw sensible.
No expert but, it strikes me that the cables where designed for the amount of current the motor would draw not the amount that could be supplied by the source pack. Maybe someone like Damien Maguire (he's the electrical engineer after all) will comment and educate us all. 🙂

Very elegant solution, sure what could go wrong?
I eagerly await chapter two

I can identify with the shoes. That ended up being a nice package, lets call it better than O.E.M.
😳🤣
Use a threaded adapter and a cable gland to make a watertight seal on that conduit tee.
I tried and I couldn't because it's tubes are too deep and these cables are flat and not perfectly round
@@Good-Enuff-Garage They have cable glands with flat style seals, not sure if that would fit or not.
@@s10mods thanks, I plan on using them on the Positive Lead in the next video

thank you

thanks this is definitely a learning experience and I appreciate the feedback
@@Good-Enuff-Garage I should have added "Probably!" at the end.
I'm sure Tom will keep us right. 😁

Good point, in this video Damien sets out to do the same thing ruclips.net/video/lhrWJ5CH0V4/видео.html
Could you fill the t connector box with something like a potting substance?
that is a good idea, maybe some of that Musk snot he likes to put in his Tesla Model S chargers
