DJI Inspire 1 RAW, with (4) TB48 Batteries
Hi,

I have an Inspire 1, and the batteries all (4) are now not working. It started with 1, then to all 4.  All batteries are giving me the "invalid battery"  "please us a certified DJI battery" "0% warning" warnings. It descended during a flight because it said the battery was 0% (it went from 62%-0% almost immediately)
  The Inspire now won't fly with it at 0% despite the batteries say they are at full charge.

What Ive tried:

!) I've updated the Firmware on the Inspire, and (I believe ) on the batteries (not sure how to tell if the battery firmware is updated. but the light on the tail just blinks red.

2) I turned on the Inspire with. the battery and let it sit idle until it runs out of juice and reset. Then recharged and tried again. Still a solid red light on the tail and 0% on the battery (despite being at full charge)
3) I cleaned the contacts with rubbing alcohol and still the same problems.


Im not sure what to do from here. Any suggestions?

You mentioned  please use a certified dji battery <------- where did you purchase the batteries by the way?

You mentioned  please use a certified dji battery

DJI, when I purchased the drone. They alwasyworked great and never had any problems. took care of them and never exposed them to too much heat or cold

DJI does offer a 6-month warranty for their batteries, but because of the structure of the product, they do not do repairs for it. Please do note that the life span of our batteries depends on the usage, flying environment, storage for a long time, temparature, flight time, charging hours and many other factors, thus we do not declare a standard life-span for our drone's batteries.

Too late for the warranty and they have been iused about 6 times. Not much at all, and they fact that they all statopped working with the drone at the exact same time tells me its the drone or frimware. (my guess anyway)

That is slightly possible or that depends on other reasons that I mentioned "sage, flying environment, storage for a long time, temparature, flight time, charging hours and many other factors".  Normally if you contact support they will just suggest to purchase a new battery because it is out of warranty.  Based on their aftersales policy of 6 months

could it be a firmware update problem? can you reverse an update? or maybe battery firmware isssue?

If there is no warning message in Aircraft Status that the battery needs to updated, the firmware of battery should be the latest version. You said you have cleaned the contact, do you mean the battery compartment?

i cleaned the metal areas that contact the aircraft. they were pretty dirty, actually. i didn’t clean the area on the contacts in the craft. they were hard to reach. i may try that.

Did you solve the problem? Please keep us updated, if the problem remains.

no resolution as of yet. i called Dji and told them about my issues, i also included that the “overheating wanting, craft will descend” warning that pops up and they said to send it back to DJi. . i’m out of warranty so i’m looking at a large bill, i imagine

did you roll back the firmware to previous version? you might wan to try that as it will confirm if issue is app, hardware or firmware related

not yet , i was unsure how to do that. where can you get previous firmware releases?

I’m having the exact same issue after a long storage.  It must be the firmware. I’ve only used the drone a few times.  Any solutions?

What charge and temperatures did you long store your battery?

The batteries are "bricked", apparently. It may happen if smart batteries aren't used for long period of time and not maintained properly. There's few YT publications how to attempt to revive them, all involving disassembly. Sometimes just unplugging the balancing wire harness, letting it sit for a while and connecting it back does the trick.

I spent a ton of time looking at links and forums regarding this Invalid Battery Warning, and finally found a solution that worked for me. I have 3 of the original batteries that came with my Phantom 3 package. One of the batteries very soon after using started this warning issue, and with all we read online about the nightmares of battery failure during flying, I never used it. Recently, I attempted again to use it with same warning appearing. Btw, the battery is fully charged. I did the cleaning of connectors and that wasn't the resolve. What did work was leaving it in the drone with all 4 navigation lights red, and letting it bleed itself off with the goal of discharging completely, then recharging. After the first light started blinking, the situation resolved itself. I took the drone out and ran it all the way down, recharged, and now it's back in the arsenal, working correctly. I hope this helps.
