    SECTION 3 INSTALLATION GENERAL This section contains mounting, electrical connections and other information required for installation. These instructions represent a typical installation and are not specific to any aircraft. PRE-INSTALLATION INSPECTION Unpacking: Carefully remove the TB28-12V or TB14 battery from the shipping container. The shipping container and packing are designed specifically for the transit of lithium batteries and approved by international transportation agencies.

  • Page 13: Installation

    INSTALLATION WARNING The power terminals of the battery are always active and energized. DO NOT SHORT TERMINALS AT ANY TIME! Extreme care and caution should be applied when handling and connecting to the unit. Danger of short circuit and subsequent arc flash, electrical burns or equipment damage can occur if not handled properly.

  • Page 16 Securing the Unit The TB28-12V and TB14 batteries are designed to be secured in the aircraft using hold- down tie rods. The hold-down bar (P/N 9017867) can be attached to the battery using the two existing screws included with the battery. The hold-down bar contains two holes, 0.310 inches (7.9 mm) in diameter, located 7.9 inches (200.7 mm) apart.

  • Page 17: Section 4 Operation

    SECTION 4 OPERATION DESCRIPTION The True Blue Power TB28-12V and TB14 Advanced Lithium-ion Batteries are designed to supply power for starting an aircraft engine and providing emergency backup power to aircraft systems in the event of primary power generation loss. It utilizes rechargeable Iron Phosphate lithium-ion cells to deliver approximately 13.2 volts DC and 26 Ampere-hours (Ah) of capacity for a -1 unit and 26.4 volts DC and 13 Ampere-hours (Ah) of capacity for a -2 unit.

  • Page 18: Operational Modes

    The software logic monitors the battery functions and provides protections for conditions such as short circuit, over-temperature, over-discharge and others. The BMS generates battery status; data that is provided to the aircraft through the 15-pin communication connector for cockpit monitoring. Data is provided in serial (RS232), discrete and analog formats.
  • Page 19 In Sleep Mode, a current of 3mA or more will transition the battery to Active Mode. The battery is capable of monitoring the terminals for an external load or charge while in Sleep Mode. The battery will enter Sleep Mode when the battery is inactive: ...
  • Page 20 higher voltage also means better power to supporting systems during an engine start. Providing Aircraft Power When the aircraft’s power generation systems are offline or fail, the unit will provide immediate power to the equipment/loads on the associated power bus. As the unit’s capacity is used, the voltage will begin to drop until the unit is fully depleted.
  • Page 21 Battery Protections The TB28-12V and TB14 Advanced Lithium-ion Batteries have built-in protections for conditions that may exceed specified operating limits: Protection Parameter(s) Action Recovery Under Voltage If discharge current < 112A Discharging Battery Voltage > 10VDC and (low current) and battery voltage < 8VDC disabled cell voltage >...

  • Page 22: Battery Communication

    BATTERY COMMUNICATION When in Active Mode, the TB28-12V and TB14 batteries present multiple status data to the aircraft for display and monitoring on appropriate systems. These are supplied as either analog, discrete or serial signals. The various outputs and their definition are supplied in Sections 4.4.1 through 4.4.3.
  • Page 23 Discrete Communication Signals Discrete signals are available to provide both basic battery status and simplified indication of battery readiness specific to the aircraft’s requirements. In some cases, where serial data cannot be integrated with the aircraft’s avionics or other messaging systems, the discrete battery status signals can be used to meet minimum regulatory annunciation requirements for lithium batteries.

  • Page 26: Section 5 Conformance

    SECTION 5 CONFORMANCE DISPATCH VERIFICATION AND IN-FLIGHT MONITORING The TB14 typically serves two primary purposes on an aircraft: engine start and emergency backup power.  Engine Start: In order to attempt an engine start, the user should verify that the FAULT signal is not active.

  • Page 27: Software Update

    SOFTWARE UPDATE A. Download the approved software update file from https://www.truebluepowerusa.com/software-updates/ to a PC/Laptop ensuring the filename is TB14_update.muf. B. Assure that the battery is idle (no charge or discharge current, no active protections) before entering Service Mode. C. Remove the aircraft cable connections from the positive and negative terminals of the battery.
  • Page 28 C. Remove the unit from the aircraft. Visually inspect the exterior of the battery casing for signs of damage or wear. Verify that the lid is secure and not loose. Verify that no damage has occurred which would prevent the battery from maintaining its air-tight seal. Inspect the battery area of the aircraft for any signs of improper installation or unusual wear.
  • Page 29 B. For a -1 unit, apply a constant current load of 26A to discharge the battery pack. For a -2 unit, apply a constant current load of 13A to discharge the battery. (Capacity check should be conducted at 23°C ±3°C (68-79°F) for best results.) C.
