Yamaha stock has the Toyota 350A controller and AC motor. Did you install a Navitas TAC 2.0 AC Controller?

I've a friend who has built over 25 Nissan Leaf packs and used Orion Jr. In his first one for himself. It's a good BMS but very $$$ and he's not used it again.
If you are building a Nissan Leaf pack, you may want to check out Zeva for your BMS they make a nice unit if you want a monitor I've used it in 2 packs. Now I have switched to ordering straight from china and get a bluetooth smart 14S BMS for around $80.
In fact I have 14 modules sitting on the shelf wired I parallel balancing now waiting for DHL to arrive with my BMS. Lol
This is a link to one of my builds if it helps:
