True Blue Power has introduced the TB50, a 50-amp-hour lithium-ion main-ship battery that fits in the space occupied by typical 44-amp-hour lead-acid batteries. Unveiled at the Aircraft Electronics Association (AEA) annual convention on Tuesday, the lithium-ion 28-volt battery replaces batteries with capacities of 38, 42, 44, 48, or 50 amp-hours and it weighs 43.9 pounds, about 50 percent less than lead-acid and nicad batteries.
As the latest member of True Blue Power’s Gen5 series, the TB50 uses the same connectors as the batteries it replaces, although it does require the installation of a vent system and a cockpit annunciator. Information available to the flight crew includes real-time state of charge and state of health but installers can also program parameters such as charge current limiting and end-of-life, minimum dispatch capacity, and engine start readiness alerts.
