Here's a little update so far. The bbshd kit came from China, didn't realize this when purchasing but it arrived in 6 days! I had it on the same day but didn't have a battery. I am off grid with solar / wind and a 48 volt battery bank so I temporarily tested on that. Today I received a ego 7.5 battery and charger, just need to rig up a mount for it and wire it in.
Almost there!
