I don't know what #DJI does with their #drone batteries to make them so sucky, but every time I put the drone away, all three of its #batteries are fully charged, yet when I take the drone out a month later they're down to half power. WTF?

I can't fly the drone without planning ahead. 🙄

@mlanger I know exactly what you mean Maria - even after a week lying, my Mavic 2 Pro batteries are down to 60% so back on the charger they have to go 🙄

@Dolphinchaz I wanted to get some aerial shots of my home in the early morning light. I guess I should've put everything on the charger last night. I probably have enough juice in one of the batteries now for a quick flight.

@mlanger Yes, but I'm always careful about how long a "short" flight is, especially in cold weather when the battery efficiency drops like a stone.

@mlanger

It's by design to prolong the life of the battery. Seems like there's got to be a better way to do it. (and it's a real challenge for things like search and rescue where you may not fly for a while but you need a fully-charged battery on short notice...)

Introduction to DJI Intelligent Flight Battery Auto-Discharging Rules

To figure out how the intelligent flight battery automatically discharges, you may need to learn the principles of two auto-discharging modes: self-discharge and auto-discharging function. Please refer to this article for help.

@mlanger It’s better to store lithium batteries at a lower charge such as 60% for a longer life span. DJI calls it Battery Auto-Discharging, and it will start to lower its battery voltage on purpose after 3 days. Not much that can be done about it as most of their batteries cannot be manually told to not discharge automatically.

@McYukon I have read something like that on their website, but it doesn't jive with their portable battery pack. I bought the 500 W version to use as a power supply when camping and boating, and it never discharges by itself. So I don't know what to believe.

@mlanger It would only apply to their drone batteries. The power bank looks like it's packed with LFP (LiFePO4) cells which are a much more stable & safe battery tech than the drone batteries which are LiPo (lithium polymer) cells. LiPo is widely used for drones because of it's high energy to size ratio with high current output, but it is the more unstable battery tech of the two.
