Giant DH Comp with 20s6p NCR18650 17ah, Besttech BMS, Cellman MXUS DD 335rpm, 25 amp infineon controller, EM3EV bag and Kiwi dropouts.
Top speed 65km/h on flat with lots of pedal power.
I could fit 120 cells inside that triangle, no room for more!
The first 20s pack I made for this build was with UR18650Y 1.5ah laptop cells, after a 16km ride the pack was burning hot and two cells in the pack had leaked and were at 0v.
So I took my soldering iron and built another one with newer NCR18650 2.9ah I had. This 17ah pack is still from laptop cells but it's only warm after the same ride. I believe they are 2C cells.
Might be fun to try with a 40A controller.
