    I am a newbie Prius and got the dreaded Triangle of death and code P0a80. I downloaded Dr. Prius and checked the battery voltages from the app. It was obvious it was block 1 giving the main issue. Attached is the readings directly from the app. Do these voltages mean the blocks are good or are they over charging? I just got this car and since i got it the code has been present. The second module has blown and did not run any other diagnostics on the car. Can I replace modules one and two or do i just need to replace the whole battery? I sent 800 on the car and really don't have the money to just replace the battery without causing a huge strain on finances.
