Straight from Autel:Anyone know the number of times the Evo 2 batteries can realistically be re-charged before needing to be replaced? I understand there are many factors such as how they are treated, used, and environmental factors. Just looking for an average number like 50 or 100.
That's great news! All of a sudden the $219 batteries are not nearly as expensive as first thought when they last 2.5 times longer than the competition. A genuine Phantom battery is not cheap either. A pair of them are $369 from Amazon. Or $184.50 each. Probably find them aftermarket for around $100 each or less.Straight from Autel:
This warranty does not apply to:
1. Aircraft(s) not utilizing most current, or up to date, and publicly available firmware.
2. Battery that cycle charged more than 200 times (100 times for refurbished batteries).
So according to Autel we should get at least 200 charges. That's 2.5 times DJI.
Very impressive resume at the bottom of your webpage. Thanks for the info.Regarding lithium batteries, I have nearly every drone made and most all have original batteries.
While the capacity will diminish in time, good lithium cells can charge for thousands of cycles. Lithium batteries for the most part are good for 10-20 years or more for automotive use which in some cases is the same as drones. There is many companies who purchase dated lithium and re-package them for sale again with a slightly less capacity. (Big Battery Company) The worst thing you can do with lithium is store it with a full charge.(swelling). Over and under charging is protected by the BCM using buffers (smart batteries) which prevent the battery from over and under charging. Also never charge a battery sub zero temperatures.
On my personal web site your find a number of lithium systems i designed for RV's.

That's not good for a battery that costs $219!I've just seen this thread. I have two Evo II batteries that have gone bad on me within a couple of weeks of one another. The number of discharges on them is 72 and 74.
My thoughts exactly. And it happened to two of them right when I needed them! I'm going to contact Autel and see what they tell me.
In my case I'm getting an "unknown battery" error. I couldn't even take off. Autel once told me to try discharging them and then charging them again. It worked briefly, but I got the "unknown battery" error again.I look forward to hearing their reply.
I remember watching a video of 808-State on YouTube, a guy who lives in Hawaii, who has been doing Autel Evo 2 Pro videos for about a year now. He mentioned he only got about 70 cycles before he started losing flight time. I don't remember by how much or how fast it degraded but they didn't just go bad all at once.

I was reading today that they will warrenty to 200 chargesAnyone know the number of times the Evo 2 batteries can realistically be re-charged before needing to be replaced?
