(NEED HELP!) Batteries and ESC

All of the ratings, motor, ESC & battery, are the do not exceed number. It’s perfectly fine to use a component in a lower demand application.

A battery rating is calculated mAh/1000 x C, in your situation, the battery can supply 260 amps (5200/1000 x 50)
For a twin motor, add the demand of both motors. So long as the total is below 260a you will OK

What battery would you recommend? The ESC are both 35 A ones.

There are 2 things to consider how many amps & how much weight can you carry. One that can supply more than 70 amps. It’s good to have a bit of overhead, something in the 75-80 amp range would be perfect.

A watt meter is cheap and a very useful tool. It’s always best to measure the actual amperage a prop is drawing. The prop determines everything, a larger diameter or higher pitch prop equals more amps. Spinning a prop faster also draws more amps.

As long as the motors can run on 3S battery MAH does not matter, 50C should handle both motors weather the airframe can handle the weight of 5200 MAH battery that is up to you.
