Hi I have this battery pack, 20x1,2v NiMH cells. I have replaced the original 1300mAh cells with new 1600 mAh cells, now the charger doesn't start charging anymore and signal an error.
2 guesses:
1) the IC had some data in volatile memory which was lost when I disconnected the cells
2) the IC regognizes the different electrical characteristics of the new cells as too different from what it expects and interpret it as cells failure
I need to understand what this IC is and how it works in order to attempt a fix, I've searched for days for "25 BRPI" "25 8RPI" "25BRP1" and all possible interpretations on Texas Instruments website and all internet but no joy.
Can someone help? Thanks!
