I just started RC cars with my kids and made first contact with LiPos and find it quite scary. A lipo counts already as damaged when the voltage drops below 3V so you have to use equipment permanently checking the voltage. In RC cars you mostly use some kind of buzzer that fires when a certain threshold value was reached. A "damaged" LiPo might catch fire randomly.
Also you have to store them in fire-proof LiPo bags and recharge them regularly to prevent voltage drops below 3V.
