Problem-statement:
For MSXV, more than 50% of modules had a dead-cell, decreasing overall pack-capacity
Possible reasons:
Manufacturing issue - if a 4.2V and 2.5V battery were placed in-series, could it kill the battery?
Testing issue - were defective cells placed in the modules (i.e., did our testing fail to catch them)?
Spot-welding - may have damaged some cells
Resonance - vibrations kills the battery pack
Next-Steps:
Research other-methods for how could a battery could drain that-quickly
Resonance - look into designing the modules to reduce vibrations (padding etc.)
