I have not had my Phantom 2 all that long. I got it shortly after they came out. I bought two spare batteries. I have maybe have 20 flights in total and all my batteries have failed at once. I want to say that their smart batteries are not very smart and I only narrowly missed my phantom going into the ocean. The cost to replace these three batteries is $168.00 Canadian each = $504.00. I definitely am not going to be doing that every 20 flights/ 1 year but....... If any of you know of a really good deal on Phantom 2 batteries it would be much appreciated. I did find B&H photo website offering them for $99.00 ($120.00 CND) with free shipping.http://www.bhphotovideo.com/c/product/1013318-REG/dji_part1_phanton_2_vision_battery.html Also a new fangled looking LCD panel batteries also $99.00 http://www.atomikrc.com/products/dj...-11-1v-rc-lipo-battery-w-lcd-display-by-venom any other options or coupon code?
