Hola a todos,
¿Alguien sabe los datos de cuántos ciclos de carga-descarga se pueden realizar en una batería TB47 TB48 de la Inspire 1 para ser descartada?

también
¿Cuáles son los criterios para desechar una batería y evitar incidentes de caídas?

Agradezco sus comentarios

Unfortunately I see 80-100 cycles being the life limit of the batteries. You can check cycle count in the battery menu. DJI's batteries seem to be lower in quality than other similar batteries.

When the batteries are no longer useful you can soak them in salt water or just take them to a battery recycler

About 80-100 cycles
Does DJI provide that information in any document? or that data where can I find it?

1) You can look at the battery chemistry listed on the pack and look at industry reporting
2) This is data based on my use of hundreds if not thousands of DJI batteries. I see over 20% loss of capacity in just 80 cycles on most batteries. This isn't even accounting for the "dead" packs that are disposed of due to a bad cell (probably 1/5 or 1/10 batteries which is super high)

What is the minimum recommended life percentage of a battery before it is discarded?

My batteries currently present 90% -94% Battery Life

Personal preference, with common sense in mind (i.e. dont use a battery with 20% cycle life left)

Aside from that it depends on your flight time needs. I generally see no point in keeping batteries about below 70% cycle life. You can keep them around for short flights if you're trying to save $ but the time lost isn't worth it.

You can get up to 200-300 cycles if you don't care about capacity loss

Hi, thanks for the inquiry. If the battery has been charged for 20 times then the battery life decreases to 90%. (200-20) / 200=90% You may also check the image below on how you will maintain your batteries. Hope that this information would help you with your concerns.

Thanks for the information,

I consult you,
This formula (200-20) / 200 = 90%, means that the maximum number of charge-discharge cycles is 200 for the inspire batteries?

Also, I ask
Is it necessary to discharge the batteries until you reach a low battery level and then charge it?
Are there problems if I leave a battery between 30% -60% and then the charge to later use it?

I appreciate your comments
regards

They say for any long time storage store them between 50 to 60%. And you also should recycle them every 10 times you charge them. I have been doing this since day one and have  never had a problem with any of my  Battery’s.

Hi. thanks for the prompt reply. Yes, 200 times battery charge cycle. However, the warranty for the batteries on Inspire 1 is 6 Months and Charge Cycle less than 200 Times. Regarding the discharging batteries and leaving the battery if you will not use it, I've attached the screenshot of documentation about these queries. Please see the images below. Thank you for continued support.

Wounder why dji wont tell people how to recover capacity to 100%.
Not all packs will recover.
But in my experiance 99% TB47S/TB48S Recovered to 95% capacity ,out of those 65% recovered to 100% capacity,and i also tested in the field.
On a TB48S in Matrice 600Pro i got 23Min at 50% ,and 38 minwith 10% to go.
No load.
Here is how to doit.
Drain your battery to point where it will turn itself off.
Wait 2hrs,charge the battery to full wait 30 min before use.
Some batteries required me to do this twice.

Forgot to add that most batteries gad 100-150 charges i was surprized myself that they came back to full capacity after so many charges.
Even biger surprise was the flight time i tought they are toast but was.wrong .
Also i have 22 sets of batteries ,around 130 packs TB47S/48S so its not 2 or 3 batteries ,i recovered capacity to 100% on roughly 90 of them ,95% on about 40,also i didint had a chance yet to do them twice to recover remaining 5%.
