Can you take pictures of your instalation?

Left side circle, there should be a gap

Are you sure you have a gap between the casing and the frame? There should be a little gap otherwise you are bending the casing and possible causing the crank to bind

I wouldnt say there are high energy density cells that have 5C, more like max 2-3C, looking at the data on nkon.nl for 21700 cell format

Mybe in terms of having a electric sports car. You have the high energy density batteries when you want high range and you have the high power batteries for high accelerarion and track times

If I remember correctly the two pin red connector that you plug the mechanical ebrake sensor. The sensor has a switch inside the brake that is pressed when the lever is released therefore making it a normally closed

Direct drive or geared hub?

Also a change from 24 to 20 can be solved with just different kind of wiring from cells to bms, alot of bms-s are capable for x cells but can be used with less if the manufacturer has provided wiring diagrams

KISS

You can also put a plastic bag over it

8 cells in parallel meaning 40/8=5. 5Ah in a 18650 format, I would like the same cells please my 21700 are trash compared to yours 18650

But "it's easy, it's just a cable in the controller"

Doubt thats 72v 40Ah in a downtube battery

Why there wouldnt be one?

What about front derrailleuer, is it properly set up? I see alot of people building mid drives remove it and commonly get their chain slipped off to the side of the chain ring
