These categories are sorted so the highest capacity batteries are at the top.

I hope you like the way the batteries are arranged.

Not hardly. All of these batteries are made by a handful of different manufacturers. Each manufacturer has it's own quality control standards. After conducting a series of tests, the manufacturers sort their batteries. The ones that perform best are sold to higher end battery companies like Flight Power or Thunder Power. The rest get split up among hundreds of other companies that may or may not sell them for a lot less money.

You get the idea. You get what you pay for!

Maybe. Some companies sell their batteries to reputable distributors and those distributors stand behind the batteries they sell. Power Edge and RFI are good examples. These batteries are a great value and have reasonable warranties.

If you plan to really pound on your batteries, be ready to spend the big bucks. You'll find that none of the battery companies are stupid. If you run your pack down to 2.5 volts and then complain because it's ruined, I doubt if you'll get much relief from any of the battery companies. Most will replace the pack at a reduced price and that's about it. None of them will replace your machine if it catches on fire.

Simple. Never run them down more than 80% of their capacity.When you get a new pack, break it in, just like you would a new engine. Limit your first flight to 3 minutes of normal flying. If you do things like tick tocks, limit them to a few seconds at most, then recharge. Make a note of how many milliamps it takes to return the pack to fully charged. As an example, let's say you're using a 2000mah pack. You never want to put more than 80%, or 1600mah, back in the pack. If, after your first 3 minute flight you recharge and put 800mah in the pack, make your next flight 4 minutes. Keep increasing the time until you're putting just under 1500mah back in. Consider that to be your maximum time and never fly longer than that. That allows you a small buffer in case you need to extend your flight for a few seconds. And never do manuevers that stress the battery for more than a few seconds at a time.

Those hot dog pilots that you see doing 6 minutes of hard 3D are all sponsored. I'll guarantee you, if you fly like that, you'll be buying batteries at an alarming rate. If you want to fly like that, be sure to get the best batteries with the highest "C" rating you can afford and even then, don't abuse them.
