Gen 3 Prius with failed two blocks P0A80

Each block consists of 2 modules (blades). Start the count from opposite side of the ECU, first pair is block 1, 2nd pair block 2 and so forth. On your block 6 and block 11 failure, maybe only 1 of the 2 modules have failed on the block. It does not mean both modules have failed on block 6 and 11, it could only be 1 on each block

You may have more weak/failed modules in your pack that your code reader has not picked up.

 

edit. Sorry I gave you information for a gen 2 earlier. You're inquiring about a gen 3 car.

The first set of "blades" closest to the ECU, that's block 1. next set of 2 is block 2......when you get to block 11, you'll find 1 (or both) of your blades to have a failed cell inside. The rest of the blocks look out of balance as well. So you will need to do more than just swap out failed modules in block 6 and block 11, the others won't be far behind if you don't get equipment to balance the entire pack.

 

Hybridautomotive.com has a good write up and has equipment as well. Many have bought it from this forum and have it for sale (used) when they sell their cars.

Each module (blade) should not be less than 7.2v. 14.4v would be a block voltage (2 together). Even if you find one at that voltage, it probably will be bad/weak. Good modules should hover around 7.4v to 7.5v or more after resting for 24 hours.
