How do I discharge Inspire 1 batteries without the A/C? Thanks!
Turn it on and wait a day or two. I also charge my rc's.
I mean, how do i discharge without the aircraft to discharge the batteries....
Ah, you mean just turn the batteries on and leave them on eh? Thanks!
I think that won't work as my batteries shut off by themselves after 10 minutes or less.
Or is there a way to keep the batteries on that I don't know, if you do please share.
You can buy devices like this or make your own. A lot of people have built discharges using auto light bulbs.

Also, use of a device like this is at your own risk and never leave a LiPo unattended while discharging (or charging for that matter). It's safest to discharge in a fireproof container like an old ammo can from a military surplus store.
Awesome reasons to buy more ammo cans!
Mine shut off after about 15mins so this won't work so well.
So, is there any problem with leaving batteries charged for 6 weeks without being able to discharge or use them?
Yes, bigtime. You never want to store your batteries with a full charge for an extended period of time. It will damage them and shorten their lifespan. It's best to store them around 3.8V per cell. The inspire 1 (and P3) smart batteries auto discharge to storage voltage after 10 days by default. You can decrease the amount of time before the auto discharge begins as well.
One thing to keep in mind is if you touch the button on the battery, it resets the countdown to discharge. If you're going to store them, store them and don't touch them until your ready to charge them for a flight.
How do you decrease the amount of time before auto discharge begins?
You change time to discharge in the DJI Go App. You'll need to power on your battery in the Inspire, then connect your controller and launch the app. Tap the battery icon and adjust the "time to discharge" at the bottom. You will need to do this for each battery you have.

I don't have the aircraft.....
You could turn your remote control on and it will flatten quite far down in 4or 5 hours, then you could use your inspire battery to charge up the RC with the cable supplied with the charger, and this would lower the charge in the battery at least enough for short term storage.
Sorry, i didn't realize you don't have the aircraft at all. I just thought you were looking for ways to drain your batteries without using your aircraft.
Your best bet would be to leave them untouched for at least 2 weeks. They will start to auto drain within 10 days and will be drained to storage voltage a few days thereafter. Just do not touch the button on the top during this period.
If you need them discharged faster, do has Cjvw suggests. That's a great idea.
That's a great idea! I just tried it and it worked. Then I plugged my tablet into the transmitter and turned transmitter on so that the table would charge and THAT worked as well. So now I can charger transmitter and tablet while draining Inspire battery and not just waste energy.
Thanks for the tip.
Hey guys, didn't see it mentioned here so thought I'd point it out...
You may want to check out the Phantom Angel dedicated discharger/calibrator (http://phantomangel.rocks). Mainly used by professional operators but could still be useful for people who need to take care of multiple batteries...
