For your info
I have solved my batteries problem.
I used DJI Assistant 2 to refresh the firmware with the problem battery,, turn off when it finished. Downgrade the Mavic with that battery to 000 version, after finished i upgrade it to the latest version.
Purchased:
MP/Batt1: came with MP, no stock in Nevada, drove to Utah, April/10/2017, no issues
Batt2: bought separately, shipped from Arizona, delivered April/12/2017, no issues
Batt3: bought separately, shipped from Arizona, delivered April/12/2017, no issues
Batt4: bought separately, shipped from California, delivered April/12/2017, no issues
April/14/2017, charged all batts to 100%. I updated to V01.03.600 firmware (FW). I refreshed each battery with the MP since you cannot see which firmware the batt is on in DJI Go 4. Nothing worse than getting out to fly and you get an "Upgrade FW" message.
April/15/2017, flew with batt1. discharged batts 2-4 to 60%.
ApriI/22/2017, I charged all batts via charging hub.
Batt4: took off hub and had to powered down
Flew with batt2, batt3, partial batt4, came home
Charged batts 2-4 via charging hub
Batt4: took off hub and had to powered down
April/23/2017, Put Batt4 in box to take back to store, thinking it could be hub...
Put all 4 batts on MP single charger, came back in 15 minutes for each batt.
Batt1: took off MP single charger and had to powered down
Batt2: no issues
Batt3: no issues
Batt4: no issues
Put all batts back on hub, batts 2-4 all powered on, found this forum thread
Put each batt on MP and did FW downgrade for each, shut off MP
Powered on MP, did FW upgrade for each batt, placed each batt on charging hub, see "note" below.
Batt1: no issues
Batt2: no issues
Batt3: no issues
Batt4: no issues
NOTE: on the night of April/22/2017 I upgraded DJI Assistant 2 to DJI Assistant 2 v1.1.0_2. The app never prompted me to upgrade it either. In fact, I could not find a "Check for updates" command in the software anywhere. So I went to DJI.com and looked for software and noticed new version number. I installed the software the first time in November/2016 when I bought my Phantom 4. The new download did not overwrite my existing application. It now calls itself just "Assistant" in the Finder (Mac), created new logs, databases, folders, .plist, etc. I noticed the new folders are called DJI Assistant 2 and old folders are called DJI Assistant2...notice the space between "Assistant" and "2". Maybe the FW did not install correctly when using the old DJI Assistant.
All batts are back to normal. Thanks, hungdang
