What’s wrong with 35E? They are fine for those low power applications. You have 60 cells for Like 500-800W. 10A continuous discharge per cell like the graph above is completely unrealistic for your OneWheel.
The only problem is that 30q and 35e are stupidly expensive right now so you might need to go with p26a. But I’m pretty sure they have the worst range out of the 3 in your case.
Speaking of I want to try to make a battery box with swappable packs.
The footpad would flip out of the way and then you could pop the battery out. Or maybe there would be an access hatch in the footpad as well. Who knows.
There’s a guy on Facebook in the Onewheel Vesc Builders group that is working on an injection molded battery box that will hold 19S2P 21700, are you aware of that? Might save us all quite a bit of work.
I think you could make a custom rear footpad with concave and then hide the extra clearance height needed for putting the 8 cells on top of the rear pack. instead of in the front box.
fitting a 24S1P A123 into the stock case dimensions mostly would be super awesome
Doing battery upgrades and staying at 15S makes sense for people who will have hacked OW hardware and aren’t interested in more speed or have a ton of xr chargers or something.
Damn three of them fit snug as a bug in the crucial width dimension. WIth extended rails and or a less space wasteful bumper with its own light solution the part poking out the bottom edge would be no problem.
I talked about this a long time ago with someone who mods OWs and he said that the V1 hub is build different than normal BLDC motors. It has multiple stators that are slightly shiftet in relation to each other. He also said that they dont work good with vesc.
