    Hi all, let me say thanks for the feedback.

    I am trying to design/alter a circuit i designed a while back, which uses the solar cell (5 watts) to charge a 12v battery (options below), as it gets dark i would like the LED's to turn on. Any advise is needed, thanks. Also should i add a overcharge circuit protection?

    I have a LED strip that is 7ft/10.5 watts (1.5watts per ft)

    Battery options
    a) 9.6v 1800mAH
    b) 12v 3000mAH
    c) 12v 6800mAH

    I have attached a schematic
