Is it neccassary to deep cycle Lipo batteries?

You do not need to deep cycle DJI batteries. See this thread for more details:

Thanks to the two Mikes.Went over ALL the threads that I hassled you with.I understand that the batteries that are not being used for long periods can have their buttons pushed to see their charge levels and if neccassary you can bring them up to 60% again which will start the internal timer again?But I don't understand why they say not to store a fully charged battery when it never stays fully charged due to the timer set in the App.bringing it down automatically to storage level?

Right -- the battery does automatically discharge itself down to the storage level. It's possible to prevent that from occurring by either pressing the battery button every few days or by charging it constantly. Either way, you'd really have to go out of your way to keep the batteries fully charged at all times.

When they say never store a LiPo fully charged they are speaking generally as not all LiPos have an autodischarge function. The Dji batteries look after themselves even when stored fully charged so dont worry about them.

That's the crux ... pressing the button resets the discharge timer.

Imagine a person who has their timer set to the DJI default of 10 days. Press that button any day in that 10 days and BHAM ... back to zero again and 10 days starts again.

1. I advised 2 - 3 day setting for auto discharge timer.
2. RESIST pressing that button !

OK ... Full charge from moment it is completed - the LiPo is accumulating damage. It is a slow process and that is why we usually do not mind LiPo being full charged for a day or so. If we didn't - we would have trouble witgh many of flight sessions over weekends etc. and be charging so much instead of enjoying flights.

What I recc'd instead though .. full charge your DJI batterys and leave then alone to auto discharge. After some weeks - charge again full and let auto work again. I see no need to babysit to 50 - 60% charge.
Doing it by full charge - means that you do not have to be concerned about watching the LED's ... you plug in ... charge ... unplug. Let the system do its job.

I have left home and travelling Middle East ... Former Soviet States etc. Before I left home - I fully charged my DJI batterys and placed in safe location. I will return home later and I am confident that my batterys will be at storage level and ready to charge.

Deep cycle is a myth that has now been shown to be wrong. Its only use with DJI batterys is to periodically reset the chip counter ... it does not in any way correct any damage or losses in cells. LiPo cells are irreparable ... damage is accumulative and cannot be reversed in any form whatsoever.

Thanks Nigel! Would you mind explaining in more detail what "resetting the chip counter " is? I'd like to understand exactly what that is and what it's doing and in what situation you would advise that might be helpful.

Hey Hi Nigel.This battery thing still has me puzzled.At below this "safe batt.storeage level" that you say is not important people say you can charge up your battery again to only below this level of say 60% so as NOT to start the internal timer?Below this point that you charged the battery does it register as one more charge on the battery when looking in the App?And then I presume below this safe storage level one may press the button to see if the battery hasn't dropped below 30% which it should not do becacause they say it might not recover its charge if left to go below 30%? Or is this also a myth?

Right -- the battery does automatically discharge itself down to the storage level. It's possible to prevent that from occurring by either pressing the battery button every few days or by charging it constantly. Either way, you'd really have to go out of your way to keep the batteries fully charged at all times.

So as SolentAir says it's O.K.to charge to full and leave themalone and they will discharge down to the storeage level(how will you know when the battery has reached its safe level of storeage or before then so you can again charge to full to fly?) depending by the days you set in the App?So now do you have to monitor the number of days of discharge that you set in the battery till you can push the button to know if that battery needs to be fully charged again?But by doing that you've then given the battery one unneccassary charge?

 

[msinger]

how will you know when the battery has reached its safe level of storeage or before then so you can again charge to full to fly?

You don't need to worry about that. Just recharge when you're ready to fly again.

So now do you have to monitor the number of days of discharge that you set in the battery till you can push the button to know if that battery needs to be fully charged again?

No. You don't need to fully charge them again until you're ready to fly.

No. You don't need to fully charge them again until you're ready to fly.

Is it the mere fact that when the button is pressed setting the timer back causing the battery to start discharging over again that when putting that particular battery back into the drone thinking it was still at 100% your battery would drain excessively causing you to crash?

DJI batteries are not able to start discharging until they have been sitting idle for at least 2 days. If you're charging your batteries the day or day before you want to fly, you'll never have to worry about when they start discharging.
