M210-RTK user and went through all sets of TB50 and TB55’s after warnings came out. Happy to report there were No problems (.913) as a matter of due diligence I always keep voltages visible on all Aircraft. The old Inspire 1 pro way to check battery health was to fly up fast and watch battery changes when battery has sat awhile b4 use. Change they did!! Fresh charges is the best way!
I left 6 of my inspire batteries fully charged inside it’s case for 5 months ...... was that bad for my batteries ? I understand I still need to charge them fully before I fly them , but leaving them fully charged in a case for so long was a bad thing ?
Is there a way to discharge the batteries without putting them in the aircraft? Or is that the only way to discharge them? If you can tell me about that I would appreciate it very much. Keep up the good work Mad RC! I really enjoy your tutorials.
You can buy the DJI RC charge cable that allows you to charge any DJI arc from the TB50 or TB55, this can also be used to charge the crystalsky batteries as well so you can discharge that way. Other than that there is currently no easy way
Mad RC I don’t understand how using the charger can discharge the batteries? And I do have the DJI charger already. Isn’t it just for charging? Or are you talking about a different charge cable than the charger itself? Obviously I am confused about what you said.
Yes a different one see the below link, you can then use this cable to charge the RC and CS batteries. m.dji.com/product/inspire-2-remote-charing-cable
Mad RC sorry about my confusion but how do I discharge the batteries with the cable you just gave me the link for? I already ordered it so I would appreciate it if you could explain how to discharge using that cable. Thanks again
Thanks for the quick reply I appreciate it. Right now I’m checking all my batteries just to be on the safe side. I definitely don’t want to be up in the air and have it fall out of the sky. Too much money tied up in it to not be as safe as possible. Thanks again
Great as always. I use 3 pair of the TB 50's and one pair is a bit strange in that when the pair hits around 25 % it drops drastically to 10% in a matter of seconds. The other two pair are fine. I like to land at 22%. I rely on the GO 4 App Battery readings.
Keep a close eye on the voltages on those that are dropping, what are they like fully charged ? Remember the key is over 4.25v per cell fully charged, at this stage it’s being recommended not to fly below 3.70v that should equate to roughly 30% until we get more info.
The batt details page in the Pilot app can't be opened...i need to switch to the Go4 app to check the cells (on different M210 that i use) Finalise the Pilot app ... and make the custom settings on the Cendence stable Dji Enterprise. Thank you

Clarification needed: is 3.7V considered as lower limit when on the ground (resting) or when in the air (under load/hovering)? My personal opinion is in line with your statement at 12:30 - resting on the ground. Still, when flying (under load, prior to landing) such battery will indicate 3.5V on Inspire2. Additionally, when full power/high current is applied (sport mode, full throttle) battery voltage will sag additional -0.2V - therefore I suspect that 3.5V in hovering can temporarily drop to 3.3V if full throttle is applied and that scares me a bit... Otherwise, if limit is to set to 3.7V in hovering, then TB50 provide only 7 to 10min flight time of Inspire2 and resting voltage when landed will get more then 3.8V... What do you think about risk of landing at 3.5V under load (possibly droping to 3.3V in full throttle)?
The current directive is land at 3.7v but I do think the 3.7v is a little connective on the I2 as it’s about 50% capacity, as the M200 is a little heavier and the capacity is then less. The sag at that point is about 0.12v so they will recover back to around 3.82v rested if you land at that point. Imo a landing voltage of 3.6v would have been a little more realistic for the I2 but they are being ovally cautious but then they were in a difficult position .
I just ran through my 12 batteries and I noticed something, ( I have mine set to 3 day discharge) the batteries that were just starting to discharge, today is day 3, were not indicating discharging by the blinking light on the side, however in the app, the battery was indicating an error, say the battery was discharging. but then once I hit the button on the battery, the error went away. don't know if this is new or not, never really taken the time to do this.. maybe this is normal.
They don’t indicate self discharge on the battery it’s self sadly, this has been something requested for a long time. Once the packs enter self discharge you don’t want them anywhere near your craft until they have been charged again. Also pressing the button on the battery will reset the time too so be aware of that.
@@MadRC thanks..I wasn't sure about this..I never fly with batteries that are not 100% charged, this is a practice that I have been doing for years, you are totally correct about that.
Can anyone direct me on how to pair sets of tb55 on a matrice 210? The pairing option seen in this video is not there for me. Edit: I figured out my issue. The pairing option is not available on the Cendence controller. Once I connected my iPad it showed up.
Battery temprature is a question = 20c is minimun take off temp . After 10min of flight it says 50c even if at 60% at 50c i am landing now - what is highest acceptable battery temp inflight? My rule is 50c !! Rated to 70c after 55c having it puff is a risk
Inspire 2 - is 15 min of flight - 3.7 v or over 50c is landing now?? But people do fly batterys below 3.6 v at what piont is a forced landing? How much degradation flying them low
I think some problems occur because of the 2 settings critical battery warnings which are as a % and not voltages presumably because of the way the battery cells can behave in flight up and down. I always set one of the buttons on back of the controller to display battery info so it's easy to have a quick look. Interesting you had a pair of inspire batteries 31 charges and one on 19 charges mad ?
That was not a matched pair on there, I just grabbed 2 packs, would not fly that that but did not match them for the video. Totally agree on the button I’m in and out the battery screen contact it and looking at those voltages
pmshop 4 I can’t comment on that as again that’s relying on something to pick it up after the fact. I can only say the safest way is to always check the voltages before take off and monitor in flight, I have always done this and it’s how any none smart battery would be monitored anyway. Checking voltages at the time is always the safest way forward.
And? You have a $3000 or more bird and go cheap on maintenance? Like the guy that spent 60K at Best Buy for a Complete Magnolia Home Theater and wanted to DIY...refused delivery. He dropped the TV and tried to bring it back.
pmshop 4 - Yes AirData now has warnings for these batteries and you can now pair them up yourself in App. Yes it is after the flight but it’s a proven record for DJI .
My batteries are on firmware version 01.00.00.71 and not.67 as you showed in the UA-cam tutorial. I’m using the latest Beta version so would that be why I have a different number on my firmware?
I agree to fully charge the batteries, but the concept for the inspire2 is, that you have a backup battery. So this concept is for the trashcan, if you allways have to fully charge and both batteries must have the same level. What does dji sell us? Reliable dual battery concept for backup or a dream, that never is gonna happen?
The duel battery redundancy does work and the I2 can fly on a single pack but the issue is you can’t fly if both packs are empty. This is why it’s being mentioned to look at the voltages and check everything is OK, while percentages calculations are a simple indication they should never be 100% relied upon.
Battery question that I can get no one to answer. Sent my Inspire 2 in for warranty repairs for a bad flight controller. I sent all 4 of my batteries. [Hundred 120 charges 9 months old.] Along with the system. When the system returned one battery after another exhibited the following behavior that I have named "battery gauge problem". The batteries charge to full voltage with all cells at about 4.2 volts. When the batteries get down to about 4.1 volts I get a signal that I have zero voltage on the battery and I need to return home. When you check the cells. All cells are 4.1 volts, but the voltage gauge obviously tells the Inspire 2 that the battery is empty or defective. Recharging the battery makes it usable again. All 4 batteries exhibit this behavior and had to be retired. Sent data to DJI and got no answer. [DJI sent me one battery but no answers] Purchased for new batteries. [Ouch] they work fine. Any idea how to salvage these batteries? I am afraid that my new batteries, one may suffer the same effect; has anyone else experienced this affect?
Assuming that you received your's batteries back and not somebody's else old crap, 120 charges is a significant number. Batteries may show a signs of aging for many reasons, but as long as they deliver reliable current everything is OK. Perform test flights after full charge, abuse the bird observing the battery status page all the time. If cell's voltage bars drop into amber or red zone too easy, if battery temperature rises to abnormal, say, 50C level ... It's time to land and replace the pair with a new one.
Great advice. LiPo RPA batteries should never be taken for granted.
What is highest cycles tb-50 you see? Still safe to fly?

My M210 won’t allow a take off if both batteries aren’t at a consistent voltage. Pairing batteries is a must as well. Thanks for the video
how do you pair TB55 on M210? I've been searching through videos and have yet to find an explanation
You need to screen shoot right before landing. What is the temprature you see?

After landing at rest if you see 3.7 v that is very low? I normally see 3.83

You can update the Pilot App from the M2E downloads page on the Crystalsky and that will bring it up to public release.
Last update was on 27sep, it stays on Dji Pilot Beta and is now on Beta-0.6.3-..... how do get the public version?
thnx ahead ! @@MadRC

OK got it ! djipilot-Official is on it .. and the Mission part seems to work .. big thnx MadRC
but .. how do i set the Cendence custom setting...
2:50 - Checking the battery firmware by using the DJI Pilot App - thank you!
Also the Pilot App has finally been updated to V1.01 on CS now.

At what cycle count are batterys not fit to fly ? Seeing problems at 60- 80 cycles
Did you know something about TB55 batteries Issue.
Suddenly falls cell voltages and crashes the aircraft.
How many cells in yellow means land now ? 3.68 v is green 3,60 is is yellow - how many in in yellow is landing now?

Emil Caruso if your tb55 is reading 98 % how can you force the charger to top it off. It’s over 4.25v though per cell
When you take off and are inflight if you do not see how many seconds of flight left you know the battery is sick.

cracking pair tho lol
Keep batterys same temp as well turn drone side to sun to warm them evenly
so whats actually the smart part on those batteries again?
Inspire 2 does balance the cells if you charge to 70% leave it turned on one hour and check settings; doing this 3 times gives perfect balance
Can you provide me a place to download the DJI Pilot App? I checked APKPurce.com and didn't see it there.
Please disregard ... I found it here www.dji.com/matrice-200-series/info#downloads
What is battery firmware today!!
Great info!
Run the flight log through AirData...that have an algorithm to detect faulty batteries.
pmshop 4 I can’t comment on that as again that’s relying on something to pick it up after the fact.
I can only say the safest way is to always check the voltages before take off and monitor in flight, I have always done this and it’s how any none smart battery would be monitored anyway.
Checking voltages at the time is always the safest way forward.
No, not after the fact. It can detect BEFORE failure airdata.com/blog
pmshop 4 but only if you upgrade your account and pay the $12.99 a month!!!!
And? You have a $3000 or more bird and go cheap on maintenance? Like the guy that spent 60K at Best Buy for a Complete Magnolia Home Theater and wanted to DIY...refused delivery. He dropped the TV and tried to bring it back.

phil devore yes they are a step ahead, no need to worry as long as it’s all the same.
Mad RC thanks for letting me know everything is ok for the different version of firmware. It had me worried because I had the different numbers.
Cell imbalance is most notable at fully charged
