While i’m waiting for parts, here’s the build log.
Each slot of the Haya will house 12S2P 18650’s. All the connections including battery sense wires are done through the pcb. Both packs will have a 40A fuse, the tracks of the pcb are designed for a 30A continuous with a 10 degree temperature rise.
The BMS is discharge circuit is by-passed from the high current path. However, it’s discharge circuit can control the Unity switch . Meaning if the BMs detects an undervoltage fault, it is able to shutdown the Unity via the switch.
closer look at all the connectors
connector for the charge port, with onboard fuse connector for the bms input connector for the switch, output connector to the Unity input connector for the CAN bus, the output connector is alllll the way at the other end of the pcb
Another interesting thing with the CAN bus, i’ve connected both 5V of each Unity together with an inline 5 Ohm resistor, this will allow me to turn on both Unity’s with a single switch.

Front riser pad
led display that will be housed inside the front riser
a little buffer to allow the NanoX’s Channel 2 to control battery voltage for a light bar

some dicking around with tests
