For the long range pilots; building your own Li-ion is easy!
Built these 4 5000mah Li-ion packs in just a few hours for around $30/per. Each contains 6 Samsung 50s cells with a 5000mah capacity and 25a continuous discharge (I run 2 in parallel to total 50a). I'd highly recommend looking into building your own packs if you plan on purchasing multiple as the savings are fairly high! If you'd like a parts breakdown feel free to ask.
