I looked. They have decent pricing on kits, but the batteries, if they are the same ones depicted in the images, are overpriced. you can find those exact batteries on ebay for much cheaper. It pays to do your research and do some price checking.
Im always wary of battery sellers that dont openly name the Cells they are using. Doesnt necessarily mean they are crap....but if they werent, wouldnt they want to sell that fact?
