TB20 Lithium-ion Battery Description

Start lighter and cut aircraft battery weight by up to 20 pounds with the Gen5 TB20 Lithium-ion Aircraft Battery. Less weight means more passengers, more cargo, more fuel and more design flexibility. True Blue Power Gen5 batteries feature an advanced Battery Management System (BMS) and provide constant monitoring, protection, and capacity data. A built-in heater ensures superior cold weather performance, down to -40°C. The TSO-certified TB20 does not require capacity checks and lasts 8 years.
