Batteries can be damaged in transit.(Japan) build them in house.
Alternators on the plane could have China knockoff parts Diodes that change a/c to d/c which will damage the batteries during charging by bleeding a/c in to the battery. but i suspect a damaged (dropped) batch of batteries.lets see if i am right.Solution 1. build you own Lithium-ion batteries in house 2.buy Lithium-ion batteries made nearby .Batteries on any passenger plane should be incased in a fire proof box as any battery can cause a fire this plane does have this box. All planes/autos have Batteries, some are lead acid which can as you know when discharging produce hyrogen.
To my knowledge they are already in an enclosed compartment. Normally LiIon batteries or any component that contains Li-Ion including pcs cannot be shipped by air, I believe. They took extreme measure to design the stuff and still Infant Mortality. Short sellers will have a field day and I am sure Hedge Fund short sellers are more interested in this than the FAA... LOL
