True Blue Power TB44 Li-ion Battery Approved by FAA, EASA

True Blue Power recently received TSO approval from the FAA and ETSO approval from the EASA for its TB44 main-ship lithium-ion battery. Its Li-ion products use nanophosphate technology that was initially developed by the Massachusetts Institute of Technology and introduced commercially by A123 Systems. OEMs are now integrating the TB17 (17 amp-hour) and TB44 (44 amp-hour) batteries into 11 business jets and helicopters. The batteries will also be offered as an STC retrofit for in-service King Airs, Caravans and PC-12s.
