Real HV battery issue or is my CVT going bad?

2008 Prius 163,000 miles, 12 volt is about 2 years old, still showing 12.4 volt after sitting over night..
car goes into ready mode fine.

drove about 5 miles this morning with the defroster on and got the red triangle of death..battery was down to one purple bar but quickly recovered..as I drove home it went to all blue bars but never got into the green.

the car has a hard time moving after stopping at a red light, ICE running all the time, but reverse feels fine. it backed into the driveway normally.

hooked to tech stream got the following
c1310 hv system malfunction
P3000-123 battery control system
P3017 (No blue star next to code)
P3021 battery block 11 becomes weak
P3024 battery block 14 becomes weak
and
ABS C1310

I have replaced mods on battery packs in the past but never had 4 fail at once and the car not moving under its own power, so Im wondering if the CVT is on its way out..

got 48mpg on this last tank so I was surprised when it started acting up this morning.

 

this pack was in the car when I got it a few months ago so I assume its never been screwed with, I have not removed it from the car yet so I don't know what I will find inside.. when I saw 4 weak I figured its not charring properly..thats why I wanted some input before pulling the car apart.. the replacement mods I have installed were in other Prii I have had over the years.. never used a torque wrench but I will.. what are the spec's?
Thanks

 

thanks, I can do the pack, not doing a cvt ..

 

last time I used a halogen fog light as a load per block. but you are right Im going to order 4.. just didn't want to waste the time and money if the codes indicated something more serious... wish someone sold replacement brass contacts reasonably , they are a pain to clean
