We have all seen the cheap knockoffs of the original DJI battery for sale on the Chinese sites.
I have read so many different things about them, and I thought I’d buy one myself to see how good or bad they really are.
I have got mine from Banggood, and this is the one (click here) and with Bangood points I only paid €45,- for it. that is less than a third of an original DJI battery. that alone makes it a very interesting deal!
After I have ordered it, the wait began… it took 2 weeks to get to me from China.
There were no import fees or taxes to be paid, another bonus!
As soon as it arrived I charged it and took it for a test, these are the results!
The battery has exactly the same look and feel as the original one.
Even the LED’s are as bright as the original one.
The original DJI ones have a warning system built in for errors in the battery.
This aftermarket one has the same error reporting system built in.
If you charge it when the battery is too warm it will warn you with a blinking light.
If you have over charged it it will warn you with a blinking light as well.
When you press and hold the power button for 5 seconds it will show you the “life” of the battery as well.
From this point of view the only big difference is the wrap they have put around the cells
Looking closer the knockoff has 20 mAh more power. the original has 4480 mAh, the knockoff has 4500 mAh.
The 20 mAh extra will give you maybe 20 seconds more flying time, so that has no added value at all!
After comparing the both it was time to get it out and fly it.
First I did some low flying and short distances to see it there were any noticable differences, and there were none I could see.
I did this for 3:30 minutes.
Then I took it for a long flight, and the results are actually pretty good!
I flew until the low battery warning, and did not use the RTH feature, I landed myself and stopped flying with some juice left.
The results are pretty good! I flew 18 minutes in a row, put the 3:30 on top of that and you have 21 minutes and 30 seconds out of the first charge. LiPo’s get a little bit better after a few charges, so I expect to get at least 23 minutes from it.
I cannot see any problems with this battery at all, like I said it looks the same, feels the same and pretty much flies the same (time)
It is a great buy for a 3rd of the price of an original battery!
I still use these batteries, and they are really good! I currently have 3 of them.
They have never disappointed me at any moment. and I fly a lot! all of the batteries have well over 50 charges on them at the moment.
