I don't get a chance to fly my drone as much as I'd like. When the weather is good, we have had errands to run. When the weather is poor, it stays stuck inside with me. I knew that most of the day was forecast as rainy. Yet, in the morning it appeared as though I'd have a chance to walk somewhere really close to run through a battery.
I have a changing pack with three, 2400mAh capacity lithium-ion batteries. Each is supposed to keep the drone in the air for a half-hour under normal conditions.
Annoyingly, however, the controller starts beeping loudly a bit more than five minutes prior to depletion. This provides the necessary warning to get the drone to its start point. I have never ventured anywhere near the Mini's 2.5 kilometer range. It doesn't ever take me long to get the drone back. The beeping basically cuts down on my flight time though.
Today, I used one, complete battery in Westminster Pier Park. It is a three-minute walk from our apartment. The sky was dark and I saw evidence of rain on the roads when I went out. I was able to buzz around in the near-empty space for a complete battery before the raindrops started falling.
