    Hello
    I'm need of some help .....so I got a charger and discharger from maxx volts to try and recondition a pack

    They pack was reconditioned before by someone and got full life on the Dr Prius app, not sure which device they used

    It's a 20 module pack

    Charging and discharging was done for 2 cycles

    On completion the Dr Prius app showed 26% battery life....with block 2 weak

    Decided to open the pack to check ... Saw the 2 modules on block 2 was swollen

    Changed it out and checked the app again it read 35% life

    So my question, is it that the pack has failed...or do I need to remove bad modules before using the charger and discharger

    'packs' do not fail, modules (cells) do. you need to replace the failed modules, then balance.

    but a pack with a lot of bad cells is not worth reconditioning.

    i'm looking at buying a 2012/13 that's been sittng a while.. if it has bad modules.. which priuses should I look for as a donor, does it share modules with other models?
