Hi,
Like several (not to say many) Mavic Pro owners I ran into a battery error issue. After a light use and only a few charge cycles the three batteries of my Mavic Pro generate an error message.
here is the app message:

and below is the controller message:

I tried to fully charge the batteries, performed all firmware and software upgrade but still having the issue.
Each battery shows deviations between cells:

I contacted the DJI support, after answering their many questions and providing pictures of the issue (per DJI support request), I got the answer many customers had: the batteries only have a 6 months warantee and I should purchase new batteries.
While I can understand that batteries become less efficient over time with each charging cycle, I can't believe all three batteries stopped working correctly after only a year of light use and in some case less than 10 charging cycle... I asked the DJI support if there is a known quality issue with the Mavic Pro batteries, I obvisously don't expect a clear answer.

Did someone find a solution to this issue besides replacing the batteries?

thanks,
Phil

Hi thanks for reaching DJI Forum, we do apologize if you are having issues with your Mavic Pro battery. Check whether the firmware has been upgraded. If so, ensure that the upgrade was successful.

Hi Gamora,

As stated in my post I did perform the firmware upgrade, that didn't solve my issue.

Thanks,

Phil

Try charge cycling.. leave the drone on and let the battery go flat so turns off entirely.. then recharge it using the Mavic Pro charger completely..

If the battery isn’t damaged this should rebalance the cells out. This looks like a classic case of cell imbalance.    If if doesn’t fix it then I suspect you have a bad battery.


I agree with you, Dji needs to relax their battery warranty a bit 6 months then no more is harsh.  Specially with only a handful of charge cycles.  most companies actually will accept battery exchanges after their stated coverage as long as no physical damage and just internal issue with cells or charging circuits.  I had a dell laptop get a new battery a full year after my coverage expired because they confirmed looking at the statuses that I barely used any charge cycles and it wasn’t holding a charge anymore so they sent me a replacement without me having to ship mine back.

Perhaps DJI should warrant the battery based on something along the lines of
100 - Weeks Owned - Charge Cycles , if the result is >0 then its in warranty.

Apparently some third party battery vendors have a one year warranty policy.
I'm usually not inclined to buy third party batteries for my camera and gear but as the genuine DJI batteries seem to have a short lifespan anyway I'm debating replacing them with this:

They might not last longer but at least they're cheaper!

Hi,
Thanks for the recommendation, I'll try to drain the batteries completely and charge them... hopefully that'll work.
I'm still discussing with the DJI support, they apparently "escalated" to another level... will let the community know how that works.

Be very careful when flying with these batteries. I had a battery error recently and the drone just landed quickly during midflight. Went from 42% to 0% and just landed right in the middle of a road. Luckily mine was still in the warranty period and I'm currently waiting on UPS label to send it back. If you choose to continue flying with this battery I wouldn't do it over water or anywhere where an emergency landing could be dangerous or cause loss of your drone. Good luck

What's the warranty on these Amazon batteries? I'd be interested in 3rd party batteries if they have a 1 year warranty.

hi guys I have had the same issue I drained the battery to low as I read above and re-charged the battery and looks like one cell is lower then the others so I believe the battery is no good
but only 6 months warranty from DJI is very poor and the price is fairly high. not sure if I will go third party battery even tho it has 12 months warranty.

a question how do I upgrade the firmware on the battery ?

Edit:  I looked at the date this was posted and now realize I'm a bit late to the party.  Whatever was the outcome of this?

My original thoughts......

3 batteries all at once?  I'm skeptical.

I would think it's possibly a problem with the charger itself - as I'll bet you used the same charger to charge all 3 batteries.

Do you have a mate or someone close, or even a distributor close by that you can take your batteries to and charge via a DIFFERENT charger?  This will rule your charger out and point back to 3 bad batteries if nothing changes.

the firmware on the battery is updated by refreshing the drones firmware ... of course, the relevant battery is connected to the drone during the update

(SOLUTION OF DJI MAVIC PRO BATTERY ERROR- ONE CELL SHOWING LOW VOLTAGE)

Hi Guys,
Did face the same problem on one of my batteries. Went through many forums and videos but were of no use. The only option (after 6 months warranty) was to do the basics.
Did search from calibration of batteries. Which is a simple cycle of charging and discharging of battery.

1. Completely discharge your battery by keeping drone ON.
2. Charge the battery to 100% after complete discharge.
3. Repeat the cycle 02-03 times and u will see the difference of one cell coming down.

It worked for me. So, thought of sharing with u all.
Thanks

Very late in the game, but it's still an issue in 2020! Did you ever solve this with the above fix? I'll try it now and post here, just so there's closure for some.lol

IT WORKED! I actually already gave up. I had the drone up for sale because I was just gonna get an Anafi,lol

So after about 6 or 7 cycles, (discharge/charge), the error went away. I didn't even notice it went away since I just had the drone on to adjust the camera settings. I just noticed there was no more Battery Error. Anyway, glad it worked out... for now. I'm fully charging now again. I'll find out if it was just a fluke.
