So I am building for the second time a bike that, quite frankly might be the death of me. The heart and soul of it consists of
30, 20Ah A123 Prismatic pouch cells. The arrangement goes like this, 1/4 inch plate of aluminum with 4, 1/4 inch lengths of all thread shafts covered buy pvc tubeing. then a single cell followed by a .030 plate of aluminum then another cell and so on. On every sheet of .030 aluminum there is a 1/4 inch long 90° bend to be attached to the heat sink via thermal transfer adhesive. Truth be told this will be the second time that I will build this bike. My biggest concern is that the hub for conventional pedaled bike will not cope with the transmission of 30 horsepower.
It's kinda terrifying when you feel things come loose, at speed.
