DJI batteries, for the phantom 3 at least, are manufactured by Sunwoda.
DJI batterys have :
Dongguan Amperex Technology Limited
printed on as Manufacturer.
I do truley think that dji makes their own battery's.. Which is in part why the prices of their battery's have dropped so much since all these aftermarket battery's started coming out.. They were loosing a lot of battery sales so they lowerd the price to be more competitive..
Sorry to spoil your day but DJI batterys are contract production and Dongguan makes them on behalf of DJI based on required specs.
I do believe that prices have dropped because its difficult to support such profiteering in face of working copies being cheaper ... as well as Discount stores selling originals ...
I have 3 batterys for my P3P .... 1 DJI original supplied in the box ... 2 non original I bought via Kiundle (who now does not sell DJI batterys) .... one is IDENTICAL in all ways to DJI original even down to labelling. Other is the typical label that says PH3 ...
ALL 3 perform identical ... LEDs same ... mAh same ... flight time same .... but the Kiumdle's were half the price of the DJI.
I did have a 4th Kiundle battery - but that went for a swim in the river and when recovered was 'blown'. I dismantled it to see if I could save any part ... as I have pals with failed DJI batterys and clones ... maybe we could marry parts ....
Imagination my surprise (actually not !) the board in the non DJI battery is EXACTLY same as the failed DJI battery my pal has ...
I am not claiming that all non DJI batterys are good ... but I get annoyed when people just paint all with bad press ... when I am sure if truth be known - most have no basis for their statements other than reading others claims.
May I suggest to those who only use DJI original to stick with that ? Fair enough to explain why you do - but please stop the 3rd hand reporting that often has little base in fact.
As another says above ... it is natural to report and moan about failures - but I agree that more people enjoy success and do not report ...
I fly my P3P to limits in cold and hot weather ... range / height etc. I video RC shows and village stuff ... do I choose which battery to use out of my 1 original and 2 'budgets' ? Yes - the one thats charged !! Label - I ignore.
This is a subject that leads to a lot of hearsay and I knew a pal who knew a guy who had xxxxx
Proof is in the pudding - not in the myths and legends ...
In my club we have over 10 P3's .... that means approx 30 batterys .... Guess how many original DJI ? 10. Why ? Because they were supplied with the P3 in the box. The rest are copies / clones budget priced and ALL perform ..
In fact the only one that has failed is a DJI original. Not through crash or bad handling.
