Question

Hello, I am working on STC3117 for voltage and SoC detection. So far I am able to get voltage correctly but current values and SoC are wrong. Please check configuration if anything wrong.

Configurations are as follow

I am using default OCV table and 660mAh battery (4.2v max) with <70 mOhm internal impedance

first OCV value = 7788

REG_CTRL

vBattTWI_Write(1, BATT_GAUGE_ADD, REG_CTRL, 0x02);

REG_MODE

vBattTWI_Write(1, BATT_GAUGE_ADD, REG_MODE, 0x30);

After configure current value

current = 65533

and

OCV = 7103

Final values while monitor I am getting

I = -1 mA

SoC = 80%

Charge value = 52
