Other Parts Discussed in Thread: BQSTUDIO
We have a 4s4p configuration li-ion pack and each cell has capacity 3450maH, bringing total capacity to 13800mAH. Expected capacity in mWH is therefore 13800x3.6v(nominal)x4 = 198270mWH.
After running the learning cycle we are getting of 62818mWH for FullChgCap (almost 4 times too small) and 13337mAH for FltFullChgQ which is close to the real value.
I am not sure why the remaining W/h value is so far off but the I/h is much more accurate. Please see our bqstudio register configuration attached. I have also attached a log file during discharge from full of 30A. The high current should not matter since we did the learning cycle with 2.5A discharge and you can see the FullChgCap value is way off even before starting the discharge.
Thank you in advance,
