I'm starting my electric go kart project and gathering parts lists to see how stuff will go together. I think I have finally settled on a Motor, Controller, BMS, Charger, Battery, and Contactor. I've put them all in a diagram to try and visualize how they will all connect together and what wiring / connectors I will need to build the harness.
I would love for someone to review the attached drawing to see if there are glaring issues or things that can be improved.
Some notes:
Thanks in advance for helping me get started!
- Motenergy ME1718 motor.
- Kelly KLS72501-8080IPS controller.
- Headway 38120HP 20S2P custom built battery.
- Chargery C10325 25A charger.
- Chargery BMS24T-300 BMS.
- Chargery DCC contactor.

Some notes:
- My goal was to have the key switch on the BMS but not necessarily the controller. This is why the power is only switched to the BMS.
- The BMS needs between 15-100V that is isolated from the balance connections. This is the reason for the 24V supply. It can take 38-75V input and input / output are isolated.
- The contactor will control both the discharge and charge (per Chargery documentation).
- The Kelly controller requires 12V input separate from the pack. I was using the Chargery discharge contactor port for this as it can output 12V / 3A.
