It's pretty common knowledge by now that flying drones around can easily go wrong. To date I have no idea how many videos I've seen of pilots that, either out of silliness or stupidity, have crashed one into someone else's favorite head. Obviously being a cautious and responsible pilot is a given but, do you still need to be concerned when it's sitting innocently on your floor?
Apparently the answer is yes.
For the record, my own personal experience with drone flight is limited to a couple of incredibly fun RC mini-helicopters (with a flight time of a mighty 10 minutes), and a couple of runs with a DJI Phantom. I'm saying that so you know going in that I have no intention of trying to stop you from being an idiotic pilot. I do want to stop you from burning your house to the ground though if that's ok.
How much would you say you know about batteries? I'm sure you have the basic parts down. Use, recharge, use, recharge, and so on...but how often do you leave these big powerful batteries charging while you aren't around. Maybe you even charge them overnight while you sleep, completely ignoring the "DO NOT LEAVE UNATTENDED WHILE CHARGING" notice in the manual you probably never read anyway.
Am I right?
Stop it! Like, right now.
Batteries are such a common thing to us that we often forget how volatile they can be, and the Li-Po batteries that most likely power your drone are on the upper end of that volatility. Understand that this is not specific to a particular brand of drone, it applies to most of them. Of course, mishandling of any battery can lead to explosions, fire, smoke, and risk of poisoning. Let me reiterate my point though, if you are charging a Lithium-Polymer battery you need to pay much closer attention to it. The construction and composition of this type of battery cause them to have a tendency to build up internal gasses while charging. When that happens, they expand and eventually explode into a fire that isn't easy to put out.
To prove my point, let me show you some proof I came across today:
Had this not been next to a concrete wall, it could have been catastrophic. With a majority of people running their photo/video businesses from home I'm sure you can see the greater risk in ignoring something like this. Despite advances is battery technology these fires are not uncommon. Read your manual and follow the battery safety instructions the manufacturers provide.
Please pay attention to your charging habits, and always check the integrity of your batteries. Especially after you crash your drone.
