Hello All,

I have a newbie question. I simply cannot find the proper procedure for updating the battery with the latest firmware. I have heard that v.2.0 is the most current but all four of my batteries are at 1.0.0.9 (2.3.0.2 Loader). I have attempted to update them through the Phantom Assistant but each time it reports there are no updates. Can someone help me out or direct me to the correct procedure?

I think your batteries are fine.  The 'V2.0' is what printed on the battery, under 'Model No.', not the software nor firmware version.  With those 'V2.0' batteries, the Loader 2.3.0.2 and Firmware 1.0.0.9 seem to be the most updated so far. Mine are the same as yours.

For the pre-'V2.0' batteries, which I also have, I have Loader 1.5.0.0 and Firmware 2.6.0.0 go with them.

All are working well to me.

Update your batteries in control software version 3.6 it may take a try or two but then you power it down and back up and it all of a sudden shows up v2.0 battery software. You have to do this for the new control software to recognize the battery correctly.

Could you Post your Upgrade status page to show the V2 version of the battery software?

Jeepinocala, I have control software 3.6 and have tried repeatedly tried to update the firmware with no success. I have confirmed that all four of my batteries are v.2.0 by checking the battery part number and version (thanks Flyingdog). I have had no issues so I guess I'm going to just trust everything is OK until a new version drops and try again. To date, I have had NO issues with the batteries as they are now.

http://forum.dji.com/forum.php?mod=viewthread&tid=3854, DJI says they stopped the battery update.

Don't worry too much about it, your batteries will work fine just make sure not to let your batteries sit around fully charged for longer periods of times since they won't autodischarge after 10 days.  You also won't get the faulty cell message if your batteries go far out of balance.
Too many folks reported issues with non functioning batteries after the firmware update was done thus I guess they pulled the update

What I did was install version 3.8 never taking out 3.6. I used 3.6 to update all of my batteries no problem but you do have to turn it on and off as usual everything you do has to be turned off then back on after you update each time. After I finished updating the batteries I then ran the rc assistant software v1.2 off their site and updated the rest off the v3.8. Pretty much a back and forth deal but works fine no issues at all. If you have a problem updating the controller then you need to run the exe off dji site rc assistant v1.2 also note make sure your batteries have a good charge during all this it fast.

Is that an older version battery?

it's not one of the original ones with the round smartbus pads which could not be updated but the model after that with the square pads

I've got 4 batteries,  3 with the square pads and 1 with the round pads and they all updated just fine.
