Other Parts Discussed in Thread: BQSTUDIO
I have the development board and my first battery management board. I based my design off the development board but removed the fuse, TS 1 to 4, and LED outputs.
I made the mistake of not grounding the fuse pin and fixed that with a jumper wire. I also wired in a 10k resistor to TS1 so that I could enable a temperature input on both the FET and Cell temperatures.
I am powering the charger input with 20V on a 4s system.
I can get the dev board to charge but not my board despite having almost identical settings.
