Gen5 TB20

Advanced Lithium-ion Battery

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, end-of-life capacity, minimum dispatch capacity and engine-start readiness. The intelligent battery systems communicate real-time, reliable and accurate state of charge and state of health. The 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. View all Lithium-ion Batteries Request Pricing
