Ludwig, Great video! Great explanations! Thanks a lot! I'm also planning to do my own eFoling project and the battery info was most unclear to me. Now it is not any more :) Looking forward to the Part 2.
This is a really useful video, thanks. One question I had is how you determined that you needed 1.5kW continuous and 3kW peak? Is that just from experience? I'm working on an eSurfboard...which I assume has additional drag compared to an efoil it will require more continuous power, but I'm not sure how much? I'd like to use the Maytag 12.5kW motor...so should estimate half that for the continous (same ratio as you) or is that overkill?
@@BrandonFurtwangler On a eFoil there is the effect of decreasing power because once you fly on the foil, the power decreases For a surfboard you will need the same power for starting and riding. And way more than on an eFoil. I would estimate 6kW to go 20kmh, and then for every double speed it's 4x the power
hi great video thx for that. my problem is that i can't get access on Excel for calculating (Battery Calculator for eFoil). could u give me a helping hand pls or any ideo to get access-rights?
you should probably have noted more clear: you are talking about LiPo batteries only here. so all the infos about voltage etc. is completely different for other type of cells. besides that: great video, thanks for your efforts!
Ampere•hours is as useless parameter as widely used for marketing purposes. I think it must be banned in a DIY community at least. About the holder I’d advice you to include a strip configuration into a 3D model, so when you assemble a battery you will have a very clear idea where a strip goes. You can make it with some bevels or with a different texture

Really well done! Thanks!
Looking forward to the next video!

Hi, in your exemple, is Imax battery = imax motor current. thanks!

Li-ion actually
Hi, I do you have the Fusion 360 battery holder files available for download ?
Sure, here: lbre.de/hp/fs/20S7P.rar
thank you@@ludwigbre
Hi. Is that LG MJ1s?
Murata/Sony VTC6
They all have different but stable color coding. Sony (already Murata) - green. LG, Panasonic, Samsung.. all are different.
