What battery for my setup?

I just ordered my first quad and I need to know what batteries I should/can use with it. I know they have to be compatible with the camera etc also, but have no idea what to get.

I want batteries that last the longest, longest flight time. I'm not bothered about speed, it's my first quad, i'm not racing it so I don't need to make it faster, just fly as long as possible in the air.
Also I'd like them from a good quality reputable manufacturer, so they are safe and reliable.

The quad I ordered is the Eachine EC250 (RTF):

Comes with:

- Brushless motor: Emax MT2204 2300KV

- Brushless ESC: 12A

- Lipo battery: Eachine 11.1V 1500mAh 25C 3S

- Receiver: Radiolink R6D 6-CH 2.4GHz (might upgrade to the R9D for increased range).

- Flight controller: CC3D (Clone version) think it's this one - OpenPilot CC3D Flight Controller Staight Pin STM32 32-bit Flexiport:

And I was planning to buy these for my FPV setup:

- Runcam pz0420m camera:

- Aomway 600mw VTX:

- OSD (not decided yet) but maybe the Hobbyking E-OSD:

Well you should be able to go up to 2200 mAh 25C 3S but that will just get you more speed. There is not really an option to get you more time out of one battery. Just multiple batteries.
Your main concerns on the LiPo batteries are:
1. Get a meter to monitor the batteries level. Don't let one cell drop below 2.o. If you loose one cell, the batteries is dead. The max per cell is about 4.2.
Here is a cheap one from HobbyKing with no balancer.

2. Time your flights to about 9 - 10 min., that way you will not drop dead out of the air and the battery should stay safe on not going too low on it's charge.
3. Make sure you use a balanced charger to charge the batteries. Some meters, when you check the battery with them will balance the cells automatically.
With three batteries, this you should get you about 30 min. of flight time.
Here is a Charger.

Good Luck!

That's incorrect a typical 2200mAh battery weighs much more that the provided 1500mAh which means the quad will be be slower and less punchy, but flight times should in fact increase. Most racers use an even lighter 1300mAh battery for racing. On that quad a longer 2200mAh will also over balance to the rear unless the front/top camera mount is removed to allow the battery to be slid forward.
 
I think you just need a 1300mah lipo batterry, you want batteries that last the longest, longest flight time and you are not bothered about speed,so I think the 1300 mah battery is very suitable for you. About your size, if you equip with a large battery, how can it fly ?
