Re: Electric Conversion log for Kahleesea

Sean and misfits,

Thanks for the info. The voltage to RPM ratio is a wrinkle I hadn't considered. Good to know before I purchase anything. Can you run the me 1115 at 30kW at 48V, or are you limited to 15kW?

I'm not keeping the ICE prop. I'm going to swap it out for a bigger prop that I can turn much more slowly and efficiently to generate the same thrust. This, coupled with the voltage, will dictate my reduction ratio.

I'm still considering if I should run 96v or 48v. There are a lot more options for accessories (like DC/DC converters and DC/AC inverters) in the 48v space.

I won't be concerned with 50% DOD. I'll be running Lithium batteries, so 80% DOD will be by cutoff. I always thought Peukert was a wanker.
