Hi there,

I am planning for my xiamo pro 2 going AWD (or 2WD) . I have everything i need, two motors, the controllers, two dashboards, diodes, cables etc. I will use a single 48V 20Ha battery. I want to use a SINGLE dashboard, with a parallel data cable that splits from the DASH to both controllers. I will use diodes to avoid speed crossover reaching back the DASH. I use scooterhacking custom firmware.

My question is. I will connect the battery BMS cable just to main controller, the second one will have no BMS connection . Is that ok??? Will I have some error (21 or another) from the secondary controller? Can I ignore the BMS using the SHFW for the secondary controller? is it a better solution to make a parallel cable so both controllers get the same BMS information from the battery? (I like this last solution I just dont know if Is ok to do that)

please help!
