There is a real possibility that BB'ing saves you more than you put into it, but this is pretty speculative.
There are hidden costs too - I have to come up with a resistive load than can dump significant amps (rebar and an 200Ohm wire wound). Some people just jack up the vehicle and spin it, but that is unappealing to me when I can always use an excuse to weld something. You need contactors, and JLD404s and shunts, stuff like that. Once you have it you can do more packs. The tools are general purpose. I investigated DIY BMS and this all seemed easier.
