[Solved]Measure a battery amps

tsunamy_boy:

CrossRoads:
Read the Pin Functions on page 7:

ISET2, pin 7:
Programming the Input/Output Current Limit for the USB or Adaptor source:
High = 500mAmax,
Low = ISET, (another pin, see below)
FLOAT = 100mA max.

ISET, pin 6:
Programs the Fast-charge current setting. External resistor from ISET to VSS defines fast charge current value. Range is 10.8k (50mA) to 540 ? (1000mA).

Also read more about these 2 pins on pages 18, 19.

And i have to calculate a resistor to different battery amps right?

Yes
