I am new here but have been watching this thread (and others like it) for a while now. I know the proper treatment and maintenance of these batteries. However. There are several videos on you tube of people fixing batteries from DJI. It is a faulty chip. I have a
Phantom 4 Pro Plus and an Inspire 1with 3 batteries each. Over the last year(even though I take good care of them 5 of 6 show no lights or will charge. Hurricane Dorian came and our streets flooded. I was going to use my phantom to get shot for the HOA and the county. Now, before the hurricane came, I charged my last phantom battery and my controller and
goggles so it would be ready when it was over a day &1/2 later. I get my drone out... guess what...battery is completely dead. So that is number 6. I am betting that if it was opened(and I may do it to prove a point) that it is 100% charged and I as a bad chip. So this is not all consumer error. It is partly bad components. I am also betting if I rechipped all the batteries, I would have 6 working batteries. The bottom line is, these batteries are between 150 and $200 each. For that kind of money they could use a $10 chip instead of a dollar chip. The cost to replace my batteries will be astronomical. And at this point in time I have no operational drones. And add one final point, my
Phantom 4 Pro Plus came with a battery that had no lights and wouldn't charge. This is turned into an unacceptable trend. Businesses putting out products with crappy parts in them. Case in point Apple. The MacBook Pro with a touch bar. If the keyboard goes bad which is a known issue. You have to pay for the keyboard, the battery, the screen, the touch bar, and the top casing to be replaced if it's not under warranty or under AppleCare. That is a prime example of the consumer footing the bill for bad design. That is exactly what's going on here with DJI's batteries. One faulty part and it cost the consumer between 150 and 200 bucks when it should have been designed properly in the first place. The only way these companies will learn is to put a dent in their profits.
