    Hello
    I am thinking about ordering two http://www.ebay.co.uk/itm/7-4-V-284...rElectronics_Batteries_SM&hash=item27dc487f39 Lithium Polymer batteries for my project, and connect them in parallel to get +5000 mAh.

    I haven't used this kind of batteries before, but I have read that if used wrong they can cause problems. The batteries I am going to order have build-in over charge and over discharge protection in them, so one problem down.

    Next one is that how I am going to charge them? Because the batteries are 7.4V, do I use somekind of 7.4V charger, and where do I connect the charger? And can I charge them in parallel connection?
    Also, can I use my device while charging the Li-Po batteries?

    You need a charger such as the Imax B6AC or the smaller cousin.
    It is a programmable computerized charger that can be set for multiple cells of different types.
    You can get them from either ebay or one of the RC outlets.
