I'm using the BQ40Z60EVM with a 4S pack. I changed the required settings for 4s operation, programmed the appropriate chemistry, and am now doing a manual learning cycle. With FETs under manual control, I fully discharged the pack until CUV and then turned off our load, waiting for the pack to rest. During the discharge, I noticed that the ACEFT would often be off, and would sporadically turn on and register the appropriate AC Adapter voltage. I'd say it was off (such that ACLW was high) about 98% of the discharge duration. The cell has now rested, so I want to charge it, but I'm still experiencing sporadic ACFET enabling. ACFET will be high for a few minutes then go low for a few minutes, interrupting the charge. BMS Studio keeps polling successfully during this time, and I can always measure the DC voltage on the input pins manually during this time. I'm trying to figure out why ACFET seemingly randomly toggles without my control to interrupt charge, even under seemingly nominal temperature and current. Thanks.
