    Hello,

    Can someone please help me to choose the best battery for my drone, im currently have
    14.8V 1500mAh 4S 45C thats works fine but short fly time, whant more fly time.

    My drone spec.
    Motor = Racerstar 2205 BR2205 2300KV
    Max.current: 27.6A
    Max.power: 950W

    Esc = Racerstar RS20Ax4 V2 20A BB2
    Input Voltage: 2-4S
    C Current:20A
    P Current(10s):25A

    Pdb = Matek Systems PDB XT60 W/ BEC 5V & 12V

    Fc = F3 Flight Controller Delux

    Please write several different kinds of battery that suits my droner, 5000mAh 30c too much?

    No good @ ~500+ grams. You might try a 2200mAh.

    @ the cost of some manoeuvrability though. Maybe lower the C rate of the battery so it does not drain quicker.
    Or higher the C rate to regain some of that power you losing in weight. Your choice.

    It depends on how you fly. For lazy cruising around you can use a lower C rating. If you are always punching it and speeding around then a higher C rating is needed.

    ok but I mean what is the maximum limit (c rate) before the motor or esc break (overheat)? i have seen some youtube movies where they explain the c rate but im not 100% how to calculate it. Thats why i posted here

    1500 x 45C = 67500 / 1000 = 67.5A total available. To see how per per motor / 4 = 16.88A. You could use a higher C rating for intense performance for your motors.

    I run the same setup different brand.
    I have used upto a 140 C
    Loads of power but drain the battery quicker. Just got to keep it to short bursts.

    Which leaves 3Amps spare plus the extra 5 for 10 seconds most esc's allow.
    I run littlebee 20a & pocket rocket 20a.
    These both handled a 90C-140C.
    Sadly that lipo puffed like a waterbomb & turned itself into a 3cell after only 5 cycles. Speed=Fun, kills Lipo's.
