Generally, Lipos are safe to use. I do understand the concerns when starting out. There are charging/storage bags available. I’ve know many that would then keep the bag inside old ammo boxes.
SMC is good place to start with.
There’s a range of chargers available. I like simple.
Most failures come from battery abuse or carelessness. My two have been my fault 100 percent. Charging at high rates, and constantly running to lowest voltage possible are also causes.
