    I need to know how to charge one battery pack with one solar panel and other battery pack with the other solar panel and I need to keep the battery packs from connect to each or they will be 9.6v and the solar panels are just 6v any ideas to keep the battery packs from sending voltage to each just to the 5v regulator

    Are the 2 battery packs 9.6V each?

    Are the battery packs connected together?

    If so, how?

    What is the capacity of the batteries (mAh or Ah)?

    What chemistry are the batteries (sounds like a Lithium ion variation)?

    Where did the 5V regulator come into this?

    The battery packs are 4.8v each
    And not at the moment I am trying to figure out how to connect the battery packs together without have to put the solar panel in a series to charge them
    2000mAh
    Nimh
    That is the start of the charging for a iPhone/iPad
    And I was thinking of using a max ic6795

    The MAX6795 is just a voltage regulator (dual). That's not what you need to charge NiMH batteries.

    In an application like this, perhaps LiIon would be easier.

    There is no reason why each solar panel can't charge a single battery since they will eventually be placed in series.

    If you're using the 9.6V battery to produce 5V to charge the iphone (or any other sort of phone -- or indeed device), then I would strongly advise using a switchmode regulator.
