    Ok so I have a 2013 140k Prius. got the p0a80 code. On the Dr Prius battery tester, it kept showing #12 as a bad block. replaced it. now it's not showing #12 BUT the p0a80 is still on there and clearly it's not driving 100% (loss of acceleration power occasionally)...

    So I've been still driving it because like I said the voltages looked good and the test on Dr Prius didn't pull up a specific block...

    until last night.

    I decided to strain the battery, by putting it in neutral and turning the brights / AC on and getting the battery pretty low.

    On the Dr Prius app AND torque app it both showed #10 as the culprit. around 1v lower than the rest. ONLY when pushed hard / stressed tested.


    So does this look like it is the problem block of the battery? just making sure before I buy another 2 modules and open this thing back up yet again...

    Side note, on the screenshot of the Dr Prius app, the differential only says 0.7volts but that was at the time the screenshot was taken. I can assure you right after that it went about 1v difference.

    Also, these screenshots were taken when the battery was pretty damn low. like 1 purple bar. And I got the alert on the dash to charge the hybrid battery or what have you...
