Ihave found on D/f most times higher c-rating will up your power a good bit.So it is well worth the added weight for more power! Harold H.
Solid Battery, Good Charge and Discharge rates. Run 2 of these on a 3D-HobbyShop SHP Extra300 with a 1100KV Motor, 40a ESC and a 12x6 Prop. Great power and depending on how hard you fly i would expect somewhere between 5-7 minutes for a similar setup.
I also have the 3s 3000mah packs and they have lasted over 60 flights with no noticeable loss of power.
