The energy density of LiFePO4 shouldn't be an issue in that application, unless you're having to carry a lot of them on foot or scratch on weight limits.
Regarding the motor, I'd suggest to look at enthusiast RC hardware, which tends to be efficient by necessity: great power density at these sizes is a question of cooling, which is easier if the components are highly-efficient.
- skohan 5y agoYeah where I am boating, I have to go a couple hundred meters by foot to get to the water, so optimizing for weight was one of my primary design constraints. Also it was partially just out of interest to see how small I could go. And I have been looking at RC motors! The main challenge there would be figuring out how to mount it - those are the skills I think I need to level up a little bit.
- namibj 5y agoFor such a footpath, I'd suggest to get a vest-style carrying harness for them. May work to just have that come with a plug and throw it in a storage case/bag on the boat. It's surprisingly comfortable to carry a lot of weight if you're just heavier than normal.
