Did you mean:

"This morning was the first full charge. Voltage of cells were equal at 4.095 except two cells that were at 4.100 volt. Less than my old pack, equal at 4.105 volt."

It is interesting that all of the cells in your new battery pack would not charge to 4.105 volts.

Mine crashed also all the time. When I removed almost all the ticks in "Settings" the stability improved. I just kept "Trip Timer", Battery Status, Battery Temp, Volts History (5 min), SoC History (5 min). The stability improved and it has only crashed 1 out of the last 10 chargings,

I am not sure if the winter has that great effect, and anyhow it is interesting to understand what effect. In my car this morning when it has been unused for more that 24 hours, outside temp was -2 C the Batt Temp Avg var 8,4. That must mean the battery compartment is well isolated.
And also what is very interesting to know for a brand new battery pack is the relationship between SoC and Batt Status Volts -maybe with temperature as the third variable.

A bad cell and a reduce range and tracking solution

Thu Apr 02, 2015 1:18 am

THIS IS FROM JOES- I HAVE INSERTED THIS TEXT INTO THIS PERSON'S POSTING.

THIS IS AN EXAMPLE OF A SPAMMER IN ACTION: COPIES AND PASTES A COUPLE OF PARAGRAPHS FROM EARLIER POSTS AND THEN FOLLOWS UP WITH THEIR OWN UNRELATED SUBJECT MATTER, IN THIS CASE CELLPHONE TRACKING. I AM LEAVING THIS AS AN EXAMPLE AND HAVE BANNED THIS PERSON FROM POSTING AGAIN. PLEASE DO NOT CLICK ON THEIR LINK.


nsps-- I agree with you. Using Canion should not in any way nullify the guaranty. I talked openly about reading data with Canion. I even wrote it down in e-mail. Concerning searching for causes ...they told me my driving habits were extracted from my car's computer. Also after the first tests, the technician told me the head office ask for 20 (?) more tests. Some 25 pages of data he told me, send to Japan... surely tracking the causes...

Siai47 --- This is bad news for many owners, meaning the life expectancy of the car might be 8 years. Hopefully for most, the car will last longer, even at the cost of somewhat reduced range. We will see in a few years, things could change then. Did you open a pack and is it easy to replace a cell ? To me it seems that the most difficult part would be to disconnect the pack and put it down.

Tracking services includes mobile number tracking, vehicle number registration tracking, land line number tracking, trace BULK SMS sender and search services like search STD Codes, search ISD Codes. Other services we provide are love calculator, finding luck with your mobile number and page rank (PR) of the website. This is the best website for cell phone tracking. http://mobilenumbertrackr.com/trace-fin ... ation.aspx

All our services shows results on Google map, which helps you easily trace and see the location of the person. This is a very popular site amongst the people of India and Indian police or cops. The Mobile no tracking software traces exact location of the cell phone number owner with its operator (service provider).
