When I was a kid, an experienced engineer told me. To build a bridge which won't fall is engineering, while to build a bridge with minimum material but it still can hold up is the best engineering. Yeah these "band-aid" fixes might be don at the first place but the engineers thought they can get away without them.

Just reminded me about Ford Pinto. They had a bladder design for the gas tank to protect leaking at the early stage. But they cut corner to save a few bugs and maybe a pound or so. That result was disastrous.

Actually beyond these band-aid fixes, Boeing trimmed down the maximum charge and elevated the minimum discharge. These all reduces the battery efficiency (W/lb). But hopefully the change result still within spec and still better then Ni-Cd batteries.
