Camry hybrid engine wont start

P0A80 Replace Hybrid Battery Pack
p3190 no engine power
Engine does not start code I believe

a few other codes i think p3000. So i started working on this Camry and when I got the car it was only running from the hybrid battery (on the screen that shows the hybrid battery gas engine and electric motor no lines were moving). So I took it apart and found one low voltage cell when i started to take the battery apart I realized all the cells were severally overheated so I ended up replacing all 34 cells when I put the car back together P3190 popped on instantly. The car drove perfect I test drove it for 30 miles without a issue. So i parked the car for 2 days then went to test drive it again and within seconds of being in the car the battery went from the top of green all the way to the bottom and P0a80 popped back on and again it run without the combustion engine. So I assumed one of the cells must be bad so I took the battery apart and checked all the cells and they are still all above 7.7V. I really do not know whats going on any help would be amazing it is my cousins only car and I really need to get it running ASAP. Thanks in advance

 

That's what I was thinking to do I have a grid charger from hybrid automotive LLC for the Toyota Prius I was thinking about charging the cells in a Prius pack and then swapping them into the Camry pack. I have seen a lot of people just throw a unbalanced cell into a Prius pack and not had a problem for a long time. So I am just wondering if there might be another problem I am not checking. Its odd to me that the combustion engine wont turn on considering that in a Prius when the battery starts having problems the engine goes into overdrive.
