Hi, would really appreciate it if someone can check something for me. If you have a JBD BMS and have a bluetooth module on it, can you check the voltage on the VCC pin for me? Is it 12v, 5v or 3v? I have a 13s unit, and a bluetooth module that I want to connect to it, but checking the voltage, I am seeing 12v on it, and that seems high to me. The BMS didn't come with the module, I am adding it, including the wiring, that is why I don't know what the proper voltage should be.
This is what the BMS, the app, and the bluetooth look like, and this is the company that makes them: https://www.lithiumbatterypcb.com/p...ent-with-uart-and-rs485-double-communication/
This is the pin (red arrow) that I am interested in.
Thanks!
