I have 4S battery, 24V PSU as source and step up to 24V as load.
Only PSU connected - battery is charging, current consumption from PSU is about 0.5 A @ 24V, current to battery is about 0.6 A @ 15V.
Only load connected - battery is discharging, current consumption from battery is about 1.1 A @ 14.2 V.
Load and PSU connected - current consumption from PSU is about 0.5 A, current consumption from battery is 0.3 A @ 14.5V.
Why is bq40z60 draining battery instead of ac adapter?
Thank you.
