I turned 80 yesterday. Have been using lipoly battery packs for about ten years and have never had an "incident" . The possibility of lipo fires is worth taking seriously, but if you charge healthy lipo battery packs at the proper amp rate, using a proper balancing charger, and don't store them fully charged, there is little to worry about. There are special safety sacks or other containers sold to store them in. I use Brinks locking ammo cases . When lipo batteries have been used and somewhat abused they develop higher internal resistance and may swell up. Continuing to use and recharge "puffed" lipo packs has led to fires. It is never a good idea to leave lipos while being charged and go take a nap, etc. It is good to keep a fire extinguisher handy. We fly in a fire danger zone and are required to have a fire extinguisher ready to use when flying electric powered models. A lipo pack may break open and catch fire in a crash scenario. Buy a good popular brand balancing type charger and power supply or a charger with built -in power supply . There are a number of chargers that will charge from two to four lipo packs at a time .Most chargers will charge Lipo, life, Lion Nimh, NiCad and Lead/acid batteries ( Multi-chemistry chargers). Many electric flyers use a high capacity charger and power supply and parallel charging boards to charge a number of packs at a time. You should learn about electronic speed controls for brushless motors including linear vs switch-mode battery eliminator circuits ( BEC's) that power receivers and servos. Switch mode BEC's , often called SBEC's, are the preferred type as they can handle up to six cell lipo packs and six servos without over heating and causing loss of control. It is also good to learn to use a wattmeter to verify that a given brushless motor and propeller combination are not pulling too many amps causing overheating damage to the motor and speed control and shortening the useful life of your battery packs. We are fortunate nowadays to have RCU and RC Groups forums providing a wealth of advice and information to beginners and "retreads". Enjoy the hobby!!
