Ok, Lipos are rated a few ways. 2s,3s,etc - means how many cells in series. 2s = 7.4v, 3s = 11.1v, etc. They also have a mah rating, 2000, 3000, 4000, etc. That is Milliamp/hours, divide by 1000 to get amp/hours. The C rating indicated the battery's output ability (amps). To figure out the output, miltiply the amp/hour rating of the batteries times the C rating. For example you have a 20C rated 3000mah pack. 3000mah =3ahx20c=60amps. Usuually the C rating refers to the continous discharge ability of the battery, not the burst rating. That is why you see batts rated as 20c/30c, the second is the burst rating. Hope this helps, you needto know this when selecting a lipo, so you do not overdischarge it(puff or fire)!
