Swapping cells of gen 2 hybrid battery

Previously i noticed issues wth my traction battery the big ol thing responsible for powering the big motor near the ice, i took the car to my parents and removed the cell, previous owner gave us a pack of used cells that he said where good, i load tested the cells of the old pack and the ones i was given and replaced all the cells wth a voltage drop above 0.40v upon a 1 minute load using a headlight as a load 55~ ish watts if i recall... Most of the cells in the active pack where above 7.7v as the vehicle had been recently driven. Now the new used cells had a sustained voltage of 7.4 ish but i also load tested theses and various of them gave me a voltage drop difference of 0.2-0.3 wich seemed to me like these where in atleast minimally better contidion. Its been a headache to do this been 9 hours already, currently midnight and i have not connected the service plug back in yet and i will probably not do so until i am sure things wont jiffy up... Anyhow does anyone have any opinions on my process or usage of lower voltage cells even tho they have a better load score than the rest?

 

I just finished installing and arming the thing, car turned on fine and cycles every 2-3 minutes or so it'll recharge itself wth ac on max seems like normal behavior so far ill update yall soon

 

Yes im aware of what wack a mole is lol things are relatively livable here, we are afterall part of the usa, the amounts of help we get from the feds keeps most things fines, yes technically we are below the us poverty level but its not as bad, although yeah i do not have the cash for a new battery lol but i always wanted to work on the hv battery itself
