Hello Alex,

I would say to go with the 4S battery, the ESC's I get in the HexaCopter kits from 3DR say they will work with 6-16.8V's. I would try and aim for a battery about 5000 mah with at least a 30c rate.

I would use an extra BEC and not the one on the ESC's, there will be a lot to power for the ESC's BEC.

I will leave someone else to pass comment on the radio / joystick option, I have not used that radio before.....

 

Regards

 

Martin.

Hi Alex,

The hard case batteries are used mainly in cars, there is another point here with the batteries and the weights, you will only get about 1/3 extra flight time (at best) for two batteries being used together, the reason for this is you are lifting the extra weight, so using more energy to lift the "dead" weight of the batteries, in an ideal world there would be a LiPo which tips the scales at 200 grams and has 10000 Mah, however these are not yet made, I'm sure you will see many people looking to add additional flight time, adding additional batteries is not the best way to achieve this.... think of a dog chasing its tail!

The best pack to use is the lightest one you can find with the right level of power for your copter, so you have no additional weight to lift over and above what is needed.
