    Make sure it's sufficiently charged before you head out to fly. Don't store it when the battery is empty and/or when it has a very low charge.

    And like all lithium batteries, don't store it more than a week fully charged. Hopefully the controller battery can be swapped out easily in the future if need be.

    It's quite the chore to open the Mavic remote controller. Check out this teardown.

    Most people should never need to replace the remote controller battery. I rarely see people doing that with Phantom remote controllers.

    I've never heard of a controller battery failing even on 2-year old Inspires (oldest product to use that configuration) even if you can't really care for it. You'll likely have a new toy by the time it needs replacement.

    My general advise for Lithium-based batteries would be to ideally charge them up to 90% and indeed don't store them with less than, say, 15% (to avoid draining below '0%')
    Does the controller work while being powered over a charging cable? That way you could even enjoy your controller when the battery is near dead.

    When I first got my Mavic 3 days ago, I performed my first firmware update from DJI Assistant with the controller plugged into the USB port of my PC and already connected to the Mavic, so that the PC could update the remote firmware and the Mavic's, through the remote, at the same time.

    Although I waited to turn the remote on until it was 100% charged, it did connect to the Mavic and I used it to take pictures and test my gimbal before even unplugging it. At no point, even during the dual firmware update, did the controller battery dip below 100%, so I think you can use your controller while charging it. Uncomfortably, but still possible.

    What is the easiest way to get a fully charged controller to a storage voltage? I'm aware of the mavic battery management system, but sounds like the controller doesn't have a similar thing.

    I think it's best to treat the controller battery like any other lithium based product. Just keep it stored at 40%

    Does it auto discharge like the Mavic batteries?

    Should you avoid charging many times? I only bought the Mavic Fly Less version so only have one battery. After a flight, the controller is at 92%. I charge my battery back up and then fly again at 92% and it goes down to 82-84%. I do this down to the 60s before recharging. My understanding is you can only charge the battery so many times, is this a good idea? I do have more batteries coming this week so I should be able to get 3 flights in before having to pack up and go home.

    I would recommend to charge batteries at 75% if you're going to do that. For flight batteries I'd charge them when they hit 20-30%. Remember when you charge the controller or any lithium while they are hot/in use you will degrade performance more of you charge the battery when it's cool and not working hard.

    I wrote up some very generic but helpful "lithium battery management" facts here:

    Leave batteries on charger

    Everything about the controller applies just as much as the mavic flight battery (and pretty much all devices from cellphones to hobby 6S packs).
