Hello,
I am using a 3DR robotics X8 model 2013, with 2 batteries in parallel( each one: 4200 mAh, 3 cells. I get a flight time of 7 minutes (voltage drops to 11.1 V). I always have an additional weight of 300 grams. I need more flight time. Do I have to change the batteries? buy a new one with 10000mAh.
Thank you

must take into account the power to weight ratio, to increase Mha also increase weight, mostly 3DR models with a basic setup do not exceed 20 minutes flight, so you have to consider what is weighing and loading capacity.
Why don't you look at eCalc to see what difference that would make....

Perhaps 4S batteries will solve your problem if your motors and ESCs will handle it?
^ I suggest the same. I'm not familiar with the X8 myself, but if you can upgrade to 4S motors and batteries, even with a lower capacity, you should be off to a good start. @Jose Eduardo, is correct, a bigger battery will weigh more, and your flight time increase will become negligible at some point for the added cost.
What brand batteries by the way? And how long have you had them?
eCalc is pretty handy but if you're just doing simple calculations this is another one: http://personal.osi.hu/fuzesisz/strc_eng/
