Sidwinder SCT Max Current Draw

I am aiming to get the smallest, lightest battery I can get for my SCRT10. I am stripping every fraction of a gram I can. If I can get my battery down to something that will last me just a heat, I will. The real limit is what I can expect the 3800KV motor to demand.

Can you give me a ball park figure on the draw? I'll consider all "punch control" like options. If I do my job right, I can sacrifice punch if my ride gets light enough.
