To be honest with you guys, the battery for the Gen1 plug-in Prius is so rock solid that it is probably the last thing to break on this machine. We have a few in-stock for many months, it is currently at 60% off because nobody needs it, it is almost as cheap as the regular Prius battery, lol @VFerdman here is the link: 2012 - 2015 Toyota Prius plug-in Lithium battery pack– NexPower Energy
Unfortunately, Dr. Prius is not aware of it and was reporting SOC as 25% at 197V. I need to research this forther about Dr. Prius. This may mean it can not perform battery tests on PiP.
Dr. Prius App is fully working for PIP, I used to own a 2015 and run test regularly, @VFerdman you can email screenshots and questions to [email protected] Best, Jack
