Just gave these 2700mah Tenergy’s a whirl. Dual mounted, XT60’s, into the battery clip. Did a hover test. This is the result. 28 minutes 10 seconds. Landing at what the screen tells me is 4%. But looking at the voltage, across the cells, I believe there was more battery to burn, but the Mavic can not recognize it. So I would feel comfortable sending this down range long distance. I consider this a success. Any ideas?
Wow 60Wh extra, and then only about 7 minutes more flight time? Sorry, but that sounds like a big waste to me.
I have to admit that I have not done similar experiments yet because I fear that the Mavic will lose its agility. And as far as I can remember, I was able to fly for 25 minutes with a single new M1x battery until about 6 percent was left. But of course, I usually land between 30 and 20 percent, which is about 19 to 21 minutes.
For this piggy-back thing that almost everyone likes to do because it's easy to implement, I can not be so excited.
But if I wanted to try something like that, then I would use Li-HV's. These batteries have the same voltage level as the DJI OEM's and usually weigh much less than normal LiPo's with the same capacity.
Nevertheless, I prefer to stick to this other 3S-2P thing, because I expect a much better result
Oh, and with almost 57 degrees Celsius, the main battery is already very close to self-destruction, which begins to my knowledge at 60 degrees. If the temperature was just so high at the end, then maybe it's OK, but that should not be considered as normal during half the flight time I think ...
