I like the innovative case and terminal set up of the GBS and the dialed in BMS/ balancing modules/ charger that will help optimize the cycle life. The GBS cells are the same price per Wh as the raw A123 cells which still need to be packed up into a protective case and fitted with terminals and balancing boards for EV use. It would take me a lot of extra work to put together a 48v/ 100ah pack out of 80 of those AMP20 cells though it would turn out to be a bit smaller.
