    I have really read many threads and watched a lot of videos on Pruis battery re-conditioning.
    I an finished reconditioning my 2014 Priys C battery with EV Peak CQ3.
    Prior to reconditioning, Dr. Prius rated the entire battery at 60 percent on the life expectancy test and gave it a clean bill of health.
    I'm trying to find information on the optimal arrangement of the reconditioned modules.

    I've found several threads on this Site, including this one.
    Just Another HV Battery Thread and Experiments | PriusChat

    Does anyone know of any other threads?

    Because my battery was okay prior to reconditioning, I was thinking of doing it as shown on the Hybrid Solution Diagnostics video on YOUTUBE. "Toyota Hybrid Battery Service and Maintenance "

    I once read something like: "You can arrange your battery modules in many different ways to optimize based on data, but why focus on differences when all modules are suppose to behave in exact same way for normal operation?"

    And with PriusC Toyota put way more demand on battery pack by having significantly fewer modules than standard Prius with longer lasting packs.

    As in I spent years working on NiMH and can loan you any testing gear you need or packs. As for rebuilding packs, these days I just haul old NiMH packs to the professional rebuilder Hybrid Car Battery Distributor | Contact Us | 2nd Life Battery and make $200. They have way better gear! As in like tens of thousands of dollars of gear that he continually replaces/upgrades several times over past decades.

    He's also best person to buy very best spare modules from.

    I'm keeping all my cars long enough that I put new batteries in them makes the most sense to me 10 years out of them are close to it etc and then when that 10 years goes by I review the situation again if the car is still in great shape and something we're interested in and we're going to keep it not needed for parts or what have you then maybe we get another battery I've got two cars that have had two batteries they're like 20 years old got them at 10 years like clockwork I buy a new d cells for my mag flashlight I'm certainly not going to buy rebuilt and recharged modules for something as important as a car generally speaking I have done it for one vehicle that I didn't think I was going to keep and it turns out the batteries lasted longer than I thought I would keep the car which it's still here too But I also only picked $550 for the rebuilt battery not anywhere near 2000

    One feller on here said his dad accidentally left his car on ready for about 5 hours and it reconditioned his hv battery. Said the hv battery bars reflected higher soc afterwards, worth a shot trying?

    sounds a lot easier than running down to the freezing garage five times a day, day after day to swap charger cables and check status... if I were smarter I'd set up a Webcam to watch it

    Yes hobby charging and all of that nonsense is kind of a pain you're running back and forth to a bench with a camera watching it or not which kinds of makes the work problematic unless you're going to sit there most of these battery guys are doing just that sitting there in the shop and running 60 or 100 modules at a time depending upon their setup I don't ever want to have to deal with anything like that like I say I'm having real trouble wrapping my head around what's so difficult amount racking up a 201 volt battery with X amount of MAH or whatever it needs I mean what's the big problem for my Prius or my volt I don't see this as being a big thing but yet when you talk to others about it it turns into re-engineering the wheel or something similar I just don't get it My understand modules racked up in series or parallel or however all that's done and so on and so forth in the voltage builds up because of how all this stuff is connected. No problem with that All I'm saying is what's the problem with getting modules to rack up whether they're round square rectangular prismatic plastic all of that same thing for my Chevy Just drop that big sucker out of there I mean what's the what's the issue That's a 300 volt setup I mean what's the problem We should be able to get a 300 volt similar battery that weighs the same 700 lb and shove it up into the car and go but apparently that's not a thing and can't be so there's your proprietary issues right there until that can be worked out some kind of way and It'll always be a bunch of crap
