Default Buying extra Lipo battery and I'm a little confused..... ??

My plane uses a 3 cell Lipo, 1800mah - 15c

I'm wanting to buy an extra battery that is a little more powerful for longer flight.
I found one cheap that is 11.1v 2200mah and 20c..... I'm just not sure which number I need to increase and why?

loosely...

the mAh number is the "fuel in the tank"

bigger number, more run time... but you can't go crazy because a bigger battery can be heavier so it takes for power to fly it.... a trade off

Ok.. thanks! Thats a good, easy description I can understand.

What does the C stand for... Current? Capacity?
AND, what is the higher numbers for? I'm guessing a bigger draw in power?

C means a few different things...

in this example it means the discharge rating of the battery....

so an 1800mAh battery rated to 15C is capable of discharging at up to 27 Amps....


here is a site with lots of info...

I have not read everything and cannot vouch for all of its accuracy, but what I saw looked pretty good.

You said you want longer flight, but that is only possible with a trade-off: Heavier batteries.

I am using the new Nano-tech batteries. They are about the same weight as the 'normal' lipo batteries, but can handle higher discharge, which means most of the time that you will keep the same power longer because they can provide the power easier.

Most importantly, the charge rate of these batteries is about 5C, so you can charge 5 times faster than with a conventional lipo battery. So, shorter pauses between flight, means more time to fly.

Have a look here if there is something that suits you: http://hobbyking.com/hobbyking/store...8&ParentCat=85
