Hey Pete, how did you measure it, and did you happen to measure it with water? Looks like the batteries are going to be very affordable for LifePo4.

so roughly 40% of the power @6V vs. 12V.

I can measure it with a full tank of water this weekend if it helps, let me know.

BTW, Ohms law is not the way to look at this, its an inductive motor load, not a resistor.
