hello guys this is my first post in priuschat, I am happy that I found this community of knowledgeable people that always help

I have a prius C with the code P0A80 and P3000 I've been reading a lot (A LOT) and I would like to replace/repair the battery pack myself why ?? because looks that here in orlando Florida I can't find somebody with enough knowledge to perform the right job, my battery pack is a shop right now but I could see the "technician" had a iMAX B6 LCD RC Lipo NiMH Battery Balance Charger I got kind of disappointed because I thought maybe he had a more specialized equipment than the one I had in my mind, he said he is going to perform the job in a day, and I know a day is not enough to analyze a whole pack with rudimentary tools.

with that said I want to be prepared by the time I get the battery pack and repair/service myself , I did open the battery first before going to the technician to make sure he is going to clean all the contacts and connections I did also measured all the voltages( NO LOAD TEST JUST MULTIMITER) and I found something interesting.

7.42
7.35
7.23
7.15
7.09
7.03
6.98
6.95
6.86
6.75
6.45
6.34
6.30
6.28
6.22
6.19
6.12
6.26
6.37
6.59
6.78
6.95
7.12
7.23
7.28
7.31
7.36
7.40

why this voltages show this pattern of decreasing in the middle?? I don't want to assume that I have a whole bad battery module, I don't really know about this car since I bought it at the auction not running thanks for your help.

If you take a look at my post you will see a similar trend with my voltage numbers but it does help to start with a fully "charged" pack. The advice given by one of the member to my post was very hepful.
