Hi,

I take it you have a walkera heli with the stock motor and 35amp Esc.

In order to get the most out of the motor and Esc combo you want your batteries to be able to deliver the max draw, in your case 35amps. To calculate this is simple, Take the c rating, in your example above 20 and times it by the capacity of the battery in your example 2200 and then divide by 1000

20x2200/1000 = 44

Walkera's tend to come with 20 amp ESc's though so anything over 20 is fine.

Ie 10c 2200mah, 12c 1800mah, 15c 1800mah etc etc

Be carefull to check the size of the batteries too, as you will probably find that the 20c 2200mah are too big to fit inside your heli.

Hope this helps

Cheers

It is a combination of c & capacity. Which heli have you got???

I had the Walkera 60 and extended the battery cage in height by inserting ali rods of about 8mm between the base plate and frames, this allowed me to use the 15c & 18c 2200mah batts.
