Calibration error codes:

If you see calib. error try to calibrate your charger again,
if that doesn't help try the following solutions:

for: I charge "nr"

  • "nr" = 1,11 - increase the minimum charge current: "settings"->"min Ic:"
  • "nr" = 2,3,5,6,7,12,13,15,16,17 - calibrate "I charge" again
  • "nr" = 4,14 - decrease the maximum charge current: "settings"->"max Ic:"

for: I discharge "nr"

  • "nr" = 1,11 - increase the minimum discharge current: "settings"->"min Id:"
  • "nr" = 2,3,5,6,7,12,13,15,16,17 - calibrate "I discharge" again
  • "nr" = 4,14 - decrease the maximum discharge current: "settings"->"max Id:"

determine minimum (maximum) charge current

The simplest way to find out your minimum (maximum) charge current is
to note down the value and ADC readings during "I charge" calibration:

I charge: 100mA

value:        [value1]
I:    100mA   [ADC1]

I charge: 1000mA

value:        [value2]
I:    1000mA  [ADC2]

use wolfram alfa to determine the minimum current:

  1. script for value1 and value2, replace value1 and value2 with your readings
  2. script for ADC1 and ADC2, replace ADC1 and ADC2 with your readings

now take the maximum of these two solutions (Substitution:) and set "settings"->"min Ic" according to it.

for maximum current:

  1. script for value1 and value2, replace value1 and value2 with your readings
  2. script for ADC1 and ADC2, replace ADC1 and ADC2 with your readings

this time take the minimum of these two solutions (Substitution:) and set "settings"->"max Ic" according to it.

determine minimum (maximum) discharge current

For discharge current use the same method as above, but this time use value and ADC readings from the "I discharge" calibration.

I discharge: 100mA

value:        [value1]
I:    100mA   [ADC1]

I discharge: 300mA

value:        [value2]
I:    300mA   [ADC2]

Minimum current scripts:

  1. script for value1 and value2, replace value1 and value2 with your readings
  2. script for ADC1 and ADC2, replace ADC1 and ADC2 with your readings

now take the maximum of these two solutions (Substitution:) and set "settings"->"min Id" according to it.

Maximum current:

  1. script for value1 and value2, replace value1 and value2 with your readings
  2. script for ADC1 and ADC2, replace ADC1 and ADC2 with your readings

this time take the minimum of these two solutions (Substitution:) and set "settings"->"max Id" according to it.
Note: if your second discharge current is not 300mA please change the number 300 (in all scripts) accordingly.
