(CNN) -- As the mystery deepened surrounding the new 787 Dreamliner battery system, U.S. transportation investigators were set to oversee more tests aimed at determining the cause of a fire central to the grounding of the Boeing jetliners.

The National Transportation Safety Board said the next round of testing was planned for Tuesday in Arizona.

Earlier tests conducted in Washington showed that a lithium-ion battery that caught fire aboard an empty Japan Airlines 787 in Boston this month was not overcharged, the board said on Sunday.
