Hi
Charge the 7S1P LiFePO4 battery pack with BQ24620,set charge end voltage is 25.12V,but when battery pack charging voltage reach 24.2V ,Charging status changes from charging to charging completed;
battery absent multimeter VBTA = 24.2V,VBAT(pack+) oscillogram:
Charging completed multimeter VBTA = 24.2V ,VBAT(pack+) oscillogram:
Charging completed multimeter VFB= 1.7V ,VFB(pack+) oscillogram:
How can I charge the battery pack to 25.12V
Thanks,
