A very long time to diagnose the "bad battery cell"

A year later after my last post. The car seems "stronger" (as it should have been a long time ago..). How come? Up to that moment the car was still 'breaking down' too many times. After approx. 1 or 2 km driving the car keeps stopping, it breaks down, it loose all 12v power and the AC motor gives an error message. Test driving with the BMS battery monitoring, provided a very important verdict; the complete 12kwh 110v battery pack is failing. The car keeps stopping after drawing as little as 1500 to 2000 Watt. It is supposed to deal with 15,000 Watt or more. The problem is that two bad cells in the battery pack are nearly dead. The fix: bypassed the set of two cells (Nissan Leaf modules). The stats on the BMS never looked better. The car seems "stronger". It can now draw 70.000 - 90,000 Watt without a problem. The problem with this car is that if something is fixed something else pops up. So if all works out well a major hurdle is completed. How long will the remainder of the battery last? I look forward to report soon more good news.
