I got my Tanic 10C 1500mAh pack from www.e-flightline.com. I see that they are currently temporarily out of stock. It took me about two weeks to get mine. The pack weighs in at 3.25oz and has individual taps for balancing. The taps came in handy last week when I left the pack in a tree for 48 hours. The pack was below 1.25 volts per cell and appears to have been undamaged. I see that there is another 10C 1500mAh pack on the market under the name of PolyQuest. Don't tell anyone, but I have been pushing my 8C Kokam pack just as hard.
