How are people suppose to use a black drone flying several hundred feet in the air in California, Nevada, Texas or any other hot location without the drone’s battery getting hot? Makes no sense. They must build these batteries to withstand this kind of heat?? 90 cycles is still not acceptable. Cell phones can go 1,000 cycles before they even begin to degrade.
I was going to compare to cell phones as well, but I don't think even those can go 1000 cycles before they begin to degrade. 1000 cycles would be charging 1.5 times a day for 2 years. After two years of normal usage your cell phone won't have the same battery staying power as it did when brand new. Of course it won't be bulging either...at least hopefully not.
