Status: offline 		Can some one tell me what A123 configuration/ cell number I would need for an electric project I am contemplating.

I want to use the eflite power 160(or comprable) which has a 60A continuous,max burst of 78, 2700w input watts, and requires a 9-10 lipo setup.

it suggests 15 lbs 3d aircraft,12-20 sport

I am planning to purchase a castle creations HV85. it is rated at 85 max amps and handle up 12s lipos

I am planning on putting it into a 1/4 scale CAP with lots off room to accomadate A123s

I chose the eflight power 160 because it seems to be a good all around motor and the HV85 because its a good deal considering jumping to the 110amp is a huge price differnce

I am not committed to either the esc or motor so if any one had other alternatives for this size airframe please chime in

Status: offline 		what would the A123 equivalent of 11 cells be and would the castle creations HV85 be enough to handle this setup with the above described motor requirement

Status: offline 		11 A123 cells is the equivalent of 10 LiPos. I'm flying a MegaMax with an 85V CC phoenix running a 12S2P A123 pack and pulling 70 amps at WOT.
