I number my batteries and make sure to run them dry, or to stop, etc. I never fast charge them or abuse them. If you're short on batteries, the Turnigy-Nanotech lipos can be purchased from www.hobbyking.com
for about $9.00 US. The IMAX does a great lipo balance charge for lipos. Make sure to order from the "US Warehouse" option, so you get them quicker. It sounds like you don't have enough batteries.
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
