how to choose battery for my drone? help please

Hello guys!

I'm a new beginner in uav field. My project is to build a Drone for inpection in aviation. I would like to know how to choose a good battery for my drone. I've seen many videos in which people explain how to choose it but i'm not sure to understand it all.

So here is my configuration

type of vehicle: quadcopter (4 motors)

flight controler: pixhawk 2.4.8

motor + propeller: cobra 2206 2100kv + HQ 6030

telemetry: rfd 900 for long range

What do i need for my project?

time flight: 20mn minimum, not less

my questions are:

1- what battery feature do you propose me? (If you could detail how you choose it, it would be great :D )

2- Do i need to change my type of vehicle? Because, i'm not sure a quadcoter can handle that. So do i need to take 6 motors instead of 4?

thank you very much :D :D :D

  • Hello! Thank you for the reply.
    Could you explain To me how you get that value?
    So does it mean that of if I want to have at least 30mn of flight I need to choose around 5000mah, 3-cell?

    Something around 3600mah, 3-cell (11.1v) should do it

"Wow, Ning2 looks really great on mobile. I had sort of drifted away as my browse-time went more on my phone, so this is great."

"I am sure most will say not again, Pixhawk telemetry. I do need help and all can be reassured that I have spent many hours scouring the net for useful information. I am not new at quadcopter flying, I started in 2012 and have progressed through many…"
