    I'm on my 3rd round of hybrid battery module failures in a month on my 2007 195K Prius. First time I relied on voltage and the computer to tell me which module was failing and replaced 1 module. After another red triangle I used a Viking battery tester on all the modules and replaced 3 modules (all I had), although the health on 7 other modules did not look great. The battery heath on these 7 was in the 80s%, showing higher resistence, although the voltage looked OK.
    I'm getting sick of playing whack-a-mole, debating if I should now replace these 7 modules for just over $200, or drop for a reconditioned battery for about $1300 from someone like Green Bean Battery.
    Any experience with Green Bean, or other recondtioned complete HV batteries?
    Am I going to do any better with a complete recondition battery vs replacing the modules myself?

    Well... A charge and balance of pack after replacing modules can make a big difference... But each rebuild of modules replaced DIY style lasts a shorter period of time and it seems like time for you to move on.

    The advantage with GreenBean and similar companies is they handle the install/swap and warranty stuff can sometime be to your advantage. Another option is Professor Joe sells rebuilt packs from Gen 4 Prius (2016-2022) and those are as close to brand new as you can get for OEM because brand new OEM prices have nearlly doubled: Prius | 2nd Life Battery

    Also check the link in my signature about Sodium-Ion, which I think is your best option.
