Car runs fine for few minutes and throws errors then stop charging the batteries

Hello all,
I have a ‘08 that sat for a long time and could not start because the 12v bat was bad and 8 cells were also bad. I managed to replaced the 12v and the other 8 cells and tested all cells to displays ~7.8V.
-Car drove and charged well for a day. The secondary as I was driving I noticed a Red triangle , a check engine light, a Maint-Req, in the display.
- I also noticed that the car will not speed and the average MPH will be 12-20 whether you press the accelerator to the fullest or not.
- I noticed that a Fan locates on The rear right side sit will start running
-
Using OBD tools I could read P0001,P0002,P0003,...
If I stop and restart the car it works every time. It will display the codes, will charge batteries for few minutes and will go back to everything I listed before.
If I disconnected the 12V bat for a minute or two, the code will not display at next start and that will last about 5 minute then everything will be back to the initial problematic state.
The gas tank is always almost full and the 12V is brand new.
Any input please

 

I used a tool I borrow from a mechanic on my way and it’s a handheld in a size 5.5”x2.5” but just one of those basic tool.
I’m in Washington DC actually and the car is out of the country and used for vacation while I’m down there

 

Thank you Dolj,
I will find a better reader and revert back. Does the behavior signal anything to you?

 

Thank you you SFO,
I simply tested with a multimeter the voltage and discovered that the 1-8 cell were reporting less voltage than others . There were below 3v.
Should I try to balance all of them and if so would this be with a Battery charger calibrates to 8V?

 

Hello dear,
I have a Bluetooth version of OBD2 and will make a trip there ASAP to collect the needed codes. Would there be a recommandés brand for the grid charging?
Thank you

 

Hello Prius gurus!
I was able to retrieve code from my 08 Prius and would appreciate any help
Here are the codes:
Hybrid fault P3000
High voltage batt fault: P3020 and 3021
ABS system fault:C1241; C1259; C1310
These were retrieved using a Bluetooth OBDII App from Motordata OBD

Thank you

 

Hello All,
I made a trip home where my 08 prius is sitting. Upon replacing block #19-20 the code were gone. I only now see a code complaint about the Batt temp sensor which I record was reconnected correctly. The car has improved but still not operating as before. The video attached was taken from the Batt monitor and I believe This is indicating an issue also because the car will stop charging the batteries until a code reset is sent . Once that happens the engine is louder than usual.

 

I did balance all of them at that time and to me now it seems like I need to go back for some extra work. The #21. & 22 are from left to right starting bear the circuit breaker correct ?

 

Here is the latest codes I received:
P0A9E
P0AFA
P3019
P3000
Please assist
