Black Falcon Drone: how do you know when the battery is full?

Mine goes green when it’s done. I usually unplug it right after that and the battery has been fine for months.

Red light just means it’s charging, nothing fancier than that. If the manual is vague, half the time these things don’t even have a proper full indicator. I just charge mine until the brick gets warm and call it done.

I just unplug mine when the red light starts fading.

I get why the light color thing is confusing but I don’t think overcharging is really the risk here that people make it out to be. These little drone batteries aren’t like the old RC car packs where you had to babysit them. I’ve left mine plugged in way longer than I meant to plenty of times, like overnight once because I forgot about it, and nothing bad happened. It didn’t swell up or lose capacity or anything.

That said, it’s not really about the charger light at all. The light just tells you the charger is doing something. Whether it flips color or not, the battery itself is what decides when it’s done accepting a charge. So if yours stays red forever, that doesn’t mean it’s still pumping power in. It might just be a cheap indicator that doesn’t actually sense the battery state.

My point is, don’t treat the light like it’s some precise gauge. Unplug it when you remember to and you’ll be fine.

Mine stayed red the whole time, then the light just went out when it was done. No green at all.

I’d say don’t trust the charger light too much, mine has never gone green at all and it still flies fine. The manual being vague is annoying though, that part I get. If it’s your first charge I’d just give it a bit and see how warm it gets.

Mine does the same red to green thing, usually takes about 40 minutes if the battery is pretty drained. I just unplug it once it flips and it’s been fine. The manual really doesn’t say much, so the light is all you’ve got.

First time I charged mine I sat there watching that red light like it was going to tell me a secret. It stayed red for close to two hours and I finally unplugged it because I was convinced something was wrong. Turned out it was just a slow first charge. The next few times it finished way faster and I stopped paying attention to the light altogether.

What I go by now is the battery itself. When it’s done, the little indicator on the pack stops blinking and just holds steady, and the pack feels a bit warm but not hot. That’s been more useful to me than the charger light, which on mine has basically one mood. Red forever.

I get why you’re asking though, the manual reads like it was written by someone who never touched the thing. If yours ever does change color, great, but don’t count on it being the signal. Just pull it once the pack indicator settles and you should be fine. I’ve been doing that for a few months now and the battery still holds a decent charge, so I don’t think I’ve cooked it yet.

I’m in the same boat, still deciding whether to pick one of these up, so I haven’t charged a Black Falcon battery myself. But I’ve used enough of these little USB chargers on other toy drones to say the red-to-green thing isn’t universal. Some go green, some just cut off and the light stays red forever, and a few blink instead. The charger is usually the cheapest part of the whole kit, so I wouldn’t treat its light as gospel. What I’d pay more attention to is whether the battery gets warm and then cools back down, plus roughly how long the first charge runs compared to later ones. If it’s still sitting there red after a couple of hours I’d unplug it and see how it flies. That tells you more than the light ever will.

Red to green is normal, but green doesn’t mean it’s actually done. Mine sat at green and still had maybe ten minutes of real charge left. If the manual won’t tell you, just pull it once it flips.
