  • The TB20 lithium-ion aircraft battery offers on-condition maintenance and is configurable to meet the needs of each specific aircraft, including charge current limit, and end-of-life capacity
  • Minimum dispatch capacity and engine-start readiness
  • Intelligent battery systems that communicates in real-time
  • Reliable and accurate state of charge and state of health
  • TB20 weighs up to 60% less, and delivers more amps per pound, than any other battery
  • This translates into more power for engine starts, more energy for emergency and back-up power, ultra-fast recharge and much longer life
  • 20 amp-hour nominal at 23°C/73°F
  • Weighs 19.5 lbs. — up to 60% less than lead-acid and NiCad solutions
  • Advanced NanoPhosphate® lithium-ion cell chemistry
  • Higher voltage during engine start — Less wear, less maintenance and increased useful life
  • Superior high-temperature and cold-weather performance from -40°C to +70°C (-40°F to +158°F)
  • More than 1 amp-hour per pound
  • Automatic internal heater
  • Overcharge, over-discharge, over-current, short circuit, over-temperature, under-temperature and charge current limiting protection
