Broken tabs on your DJI Mini 3 Pro Mini 4 Pro battery? Fear not. Here is a simple solution to keep your battery in place with only a 1g weight penalty. It’s a hair bobble. You could also use an elasic band.
To put it on, fold the rear arms, and open up the hair bobble over the arms to the front of your DJI, then open up the arms and bring the hair bobble back. Then, pull up the hair bobble over the back of the battery.
To put less load on the tabs of your batteries that haven’t (yet) broken, then you can also remove the securing tabs in your charger. I’ve done this using a stanley knife, and a nail file.
Don’t do this if your charger is under warranty, or if you don’t want to devalue your charger. If you have a dremel or if you are very patient with a nail file, you could do it this was too.
I am looking at modifying my good batteries too by sanding back one half of the tabs as this appears to be the problem with over-stressing the plastic. I’ll post an update on this.
Just be aware that your 1g change means you’re no longer flying a 249g drone, you’re now flying a 250g drone; which dramatically changes where / how you can fly in the Open A1 Category in the eyes of the CAA
The DJI spec sheets list the Mini 3 at 248g and the Mini 3 Pro at 249g.
I don’t mean to offend your weighing scales but the calibrated scales DJI use in their laboratories when seeking FAA type-approval are probably more accurate
It’s also worth pointing out that there always design tolerances. 1g in weight is only 0.4% of the overall weight of the drone. A company would not be able to mass produce this to this tolerance. So given that, the specifcation would be the maximum design weight, which in reality would be an item that could be near-guaranteed to be below that.
By my estimate (putting 30 of them on and dividing) is just a smidgen over 0.5g. Double the elastic band in your hand before putting it on to get a good tension. You can alternatively go over the front arms and back around the battery too.
It’s probably best to stay on the safe side and use an elastic band to keep your drone below the 250g limit. It’s probably best to use a fresh one each time, or just check if it’s a bit perished.
Different weights of batteries
Incidentally, I thought I’d weigh my three batteries.
One weighs in at 83g the other two weigh in at 81g. Incidentally, the one with the cracked tabs is the heavier one. All three are DJI Mini 3 Pro batteries.
I weighed them inthe middle of the scales and moved them to the edge for the photo you cheeky blighter. I also off-weighed them, checked the tare each time, and repeated.
It’s just an added extra for people interested in the weight penalty, that’s all.
