(20c X 1800mah LiPos should be around 36 amps. 2 together, 20c 3600 or 72 amps. all consideration is the 20 peak or burst or constant.

If you did it you have to ask how you need to hook them up and charge them etc, so doing this might not be for everyone.

I dont like the word BURST on a battery, to me it was big mistake saying 12c constant and 16c BURST. When I got my plane I was sort of afraid of LiPos because it said 10c burst. I thought all along it ment boom. Later after working them into the SV I reolized a lot of other people thought the same thing about bursts. There word should have been peak draw or just peak anything but burst. The LiPos are nice to use.
