I did order my belt cp with this extra battery:

Extra Li-Polymer Battery (RC Pro X): RC Pro X 11.1V 18C 2200mAh Li-Po

but it seems that the battery is out of stock so the boss proposed to send me (2x Extra Li-Polymer Battery (RC Pro X): RC Pro X 11.1V 12C 2200mAh Li-Po) instead of 1x Battery with 20c. what is the ratio and difference between those 2 batteries?

Those batteries don't have a good enough current rating for extreme 3D flying and cant charge as fast either.

The stock battery (EK1-0186) in the RTF kit has a 20C rating. I haven't checked the current pull in the Belt CP, but I would say that a 12C battery is going to get destroyed pretty quickly in the Belt CP...

The C rating indicates the maximum recommended average discharge current for that pack and is used to help you determine the maximum discharge rate. To determine the maximum discharge rate, multiply the “C” rating by the pack capacity
i.e.
Stock EK1-0186
= 1800mAh cell x 20C rating
= maximum discharge rate of 36,000mA or 36.0A

RC Pro X 11.1V 18C 2200mAh Li-Po
= 2200mAh cell x 18C rating
= maximum discharge rate of 39,600mA or 39.6A

RC Pro X 11.1V 12C 2200mAh Li-Po
= 2200mAh cell x 12C rating
= maximum discharge rate of 26,400mA or 26.4A

C Rating
LiPo cells are also commonly given a C or current rating. This is the maximum average recommended discharge current for the cell. For example, the Thunder Power 1900mAh packs have a 6C rating. To determine the maximum recommended discharge rate multiply the capacity times the C rating. 1900mAh x 6C = 11,400. So the maximum recommended discharge rate would be 11,400mA or 11.4 amps. If your application has a higher amp draw, remember that LiPo cells can be wired in parallel, and with 2 cells in parallel each cell sees half the total current. With 3 cells in parallel, each cell see one third the current.

first off a 3800 belt cp motor is 20 amp max. You want to use 2200mah 12c. 2200*12=26,400ma thats 26.4amp discharge rate your motors max current is 20 so your fine I would take that deal.

EK5-0006 Brushless Motor 1 Unit
EK1-0350 25A Brushless Speed Controller 1 Unit

The brushless motor is 20A max
the bm speed controller is 25A max, so it means that i will have a max of 25 with my belt cp? so with the battery 2200 12c i have 25.4A so i'll not destroy the battery is that?

After my first post and updating for the math, I have to agree with tryan02...

The ESC is only rated for 25A, and the proposed battery will supply 26A. You should be OK...

The 25A is continuous, max on the ESC is actually 50A.

You should still be OK - especially if you are learning.
