3 Generations of ZERO Motorcycles Battery

Making some cleaning in my lab I had in front of me 3 differents generations of ZERO BATTERY all together so I thought you would like to discover these more in details! EDIT: at 10m30s I meant the BCB module is 28 cells in serie of 14s2p, not 56 cells in serie EDIT: at 10m12s I meant in SERIE not parallel.
