And a flammable fuselage too
As nobody has mentioned this point yet, I will now, as if B.plans to vent burning electrolyte via a high pressure vent folly scheme, they have a flammable fuselage to contend with also. The only feasible and sensible is reverting to Ni-Cad as Joe Sutter and competent retired B engineers would have done and dump the lethal Li-ion nonsense until an improved and stable versions are developed. Otherwise they will have burning epoxy primary structure with a self ignition temperature around 580 degrees F to add to the present lethal mix. This is folly and nonsense of the highest order and unworthy of any rational aeronautical engineering company.
