There's really only one place, more or less, that's: www.hobbyking.com
. Anyways, order the 'Turnigy-Nanotech' line of lipos, just get the appropriates size, voltage and milliamperes you're supposed to have. Each product has a 'US Warehouse' listing/option, use that, unless you want your orders to take awhile. They also sell the IMAX B6 balance charger which is great bang for your buck.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
