warrior 9918 esc - Lipo questions

[BrianG]

You could go up to 6s lipo if you wanted to. 6s lipo is roughly like 18 cells, and the 9918 was found to be capable of 20 cells.

14.8v lipo (4s) would be fine. High mAh ratings doesn't mean that much except add to runtime and weight - the system will pull whatever current it needs; the battery doesn't "push" out a certain current no matter what it's rated for. As long as you keep the current draw within ~90A, you'll be fine. You will however want some type of low-voltage cutoff to protect agains overdischarging the lipos.
