Unknown Issue with Hybrid System

Hey all, after using the Hybrid Assistant app on the Google Playstore to find out that block 1 is bad in my battery i replaced the two cells in the block and put it back in the car. I originally ran the OBD scanner because i had a loss of power to the gas pedal and the hybrid system warning came up and thats how i found out about the bad block but i figured after replacing the bad block it would stop and drive fine. But the same issues are still happening i'll list the ones i can think of below.
-Delayed Throttle Response (have to slam the peddle to get any power sometimes)
-the cooling fan for the battery is constantly on and sucking air
-after turning the engine off it shakes quite heavily
-barely any power in the gas pedal (flooring it and i barely get to 50mph after 50-60 seconds
TLDR: i replaced a bad block and the issues above didnt go away
any help would be appreciated, im quite capable to fix what the issue is if i know what it is.
