Great reply from dandare, there are 2 C numbers to be aware of - the discharge number, 25C 90C etc, a discharge number (higher 'burst' number is sometimes also quoted) and The C number used for charging, we charge at 1C so as above a 5000 mAh battery is charged at 5amps and will take less than an hour etc.
There are no tricks to lipo's, none of that old nimh/nicad marlarky, it's an easy life - charge, race, top up. race again - yes you can manage a meeting on one battery.
Must use a dedicated lipo charger, they take a charge in a different way, as above do not allow to over discharge, have seen flat lipo's from being left in a car connected with the switch off etc, if they over discharge a lipo charger will refuse to charge them. There are sacks & box's for placing the batteries in when charging in case of problems and you may be expected to use one.
Now you will want to know about brushless motors, 2.4 radio's and what to do with your time between heats.
