Other Parts Discussed in Thread: BQSTUDIO
Hi,
I'm using a B35100 in "Coulomb Accumulation" mode with a multi-cell (4 x Li/SOCl2) configuration. The calibration is done ( current and voltage ).
I'm trying to understand how to get the unit of the coulomb counter.
In the TRM § 11.1 the unit of this data is Ah, but for example with a fix 300 mA Load during 10 minutes the delta off the AccumulatedCapacity data is: 4900 .
Each time I test it the ratio is almost constant: (600*300) / 4900 = 3.6
What is this value? Is it possible to get it from the DF data?
