Glad it is all coming together and mobile on a static test

I bought some multicore 30A cable but it's a bit too heavy duty. I am also wondering if using the deans connectors is overkill.
If it comes to it, I found a spool of speaker wire from B&Q works very well. It is stiff in very short sections but longer than 10cm or so and it works fine. I used that in The Honey Badger and works OK for that application. XT30 or 60 connectors work very well for this as well.
