Gen5 TB50

Advanced Lithium-ion Battery

Gen5 lithium-ion aircraft batteries address the challenges of lead-acid and NiCad battery technology. The TB50 offers on-condition maintenance, eliminating expensive battery maintenance, frequent capacity checks and low-voltage operational delays.

These intelligent battery systems deliver more accurate and more reliable state-of-health and state-of-charge data than any other battery on the market today.View all Lithium-ion Batteries Request Pricing
