    Hello I am going to pick up a new hybrid battery from Toyota for a 2014 Prius.
    I have used the OEM packs for second generation repair in the past. I was wondering if there is any difference in the modules the put in the gen 2 and gen 3. I'm aware of the case and connection differences but are they using the same primearth modules for both versions?
    Why not use a gen 3 pack? A $500 difference for 28 modules, so I'd like to know if there is any good reason to pay the extra money. I've rebuilt several traction batteries so a module swap to different case is not an issue.
    Thank you

    Modules same but in gen3 case you get parts you do not in gen2. If not plug in same thru at least 16 I believe .
