Hi, everybody. My Ion 2011 with 133.000 km. and 25Ah. has a problem with the cell 69. Like, high resistence. It´s very fast discarging and marks 2.6 v in max acceleration. With half charge i can see the turtle without great acceleration and 0.750mv difference between cells. When I charge always the 69 can´t be totally charged. And needs a lot of time trying and discarging other cells. The battery can´t be balanced correctly. Always with 16 bars.
In summer the problem is minor. (CMU reading better?) .
The problem is cell 69 o CMU 10. I think, generally in forums the problems are with 10 CMU or cells in this module. Curiosly always the same.
Well, I think to change the LTC in CMU 10 and the cell. Maybe the cell is ok. but I prefer the safe way.
The analog LTC 6802g-2 (2008) it was replaced (2011) (upgrade) for LTC6803g-2 .https://www.analog.com/media/en/technic ... 0324fa.pdf
" It is pin compatible with the LTC6802-2, providing a drop-in upgrade."
LTC6802-2 Multicell Battery Stack Monitor with an Individually
Addressable Serial Interface
Functionally Equivalent to LTC6803-2/LTC6803-4. Pin Compatible with the
LTC6803-2https://www.analog.com/en/products/ltc6 ... t-overviewhttps://www.analog.com/en/products/ltc6803-2.html#
Analog recommends to use LTC6803-02. Maybe a long term, knows problems with LTC6802-02.
How you see to use the LTC6803-02. It's a big risk?.
I replaced the charger. Thank a you a this forum and I try to fix the battery.
