Wish I would have done a little more reading before purchasing one of these. I haven't received it yet but I see where some people can't get them to work while others don't seem to have a problem. What gives? I understand with these being intelligent batteries it would be possible to make these useless by DJI, but I would think they wouldn't sell many of them if that was the case. Is it a matter of firmware? Thanks.
Personally - I would say you have already answered your own question - "they wouldn't sell many of them if that was the case".
I honestly believe that many problems of whatever nature are too often easily blamed on another factor instead of trying to really find out what was cause.
Let me give an example :
53" span 5kg biplane with 15cc gasoline engine up front ... flying good ... flypast at moderate height downwind ... flip inverted and bring her round for an inverted pass going upwind. Just before she reaches me - she dives into the tarmac and shatters not only model but engine etc .
On the video I immediately shout I went wrong way with elevator ... down is up ... up is down when inverted.
But studying the video later shows clearly that she dives at a steady straight line into the tarmac even though I am moving the sticks .... NO elevator movement at all. Diagnostics then prove an intermittent elevator fault causing it to fail at times.
The moral is : what you think and jump to conclusion - can often be wrong. I suggest that a large number of battery stories are like that.
If so many Powerextra Batterys are being sold and many of them NOT reported as failed - then something else is going on.
I honestly do not believe that DJI would be so stupid as to create a blocking code in FW to prevent use of other batterys - that would be illegal in many countries. Even Microsoft had to stop doing it with Windows and their exploitation of the Browser wars.
I do accept that it is possible for lesser quality control to be on some batterys - of course i would be stupid to claim otherwise. But I would also be naive to think that DJI batterys were without any faults. Nothing is perfect. Everything is also built to a price.
As to the Corvette and tyres ... yes well as I know two who owned the original Corvette and suffered the cracked body shells that were common faults after a few years of use ... we shall put that aside ... a fault that also plagued the Shelby Cobra in fact ...
A fact that all seem to ignore - nearly ALL proprietary items of whatever item it may be - ALL spheres of life have most often higher price because they are proprietary. And it is no g'tee of quality.
I bet most reading this prefer a brand of gasoline ... if you only knew the truth.
