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. πŸ™„

@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.

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.

@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.
