The battery itself looks very nice, larger and heaver then the DJI 2200mAh. I had to cut grooves in the battery door for the connections to run outside because it is a ton easier then cramming them inside.
Pros: Slightly longer flight times
Charges and discharges better then stock batteries
Very good price
Cons: Heavier
Bigger
Have to cut to get it to fit
The reason I bought these batteries is because the Mad Dogs were on backorder. So far they have been OK. I am running a gimbal and stock props on my phantom. I got 8:30 of flying steady before I got the first red light. Then I flew to 9:30 and safely landed. I could have gone longer. I just ordered 9 inch carbon fiber props from DSLRpros.com.... Those should increase my flight time i would think.
