Overview

Cut your aircraft battery weight and increase your useful load. The TB14 is designed for smaller, 28-volt fixed wing aircraft. You’ll gain faster and cooler engine starts and benefit from superior performance in extreme temperatures (-20°C to +70°C). The TB14 features built-in charge current limiting to protect your aircraft's alternator or generator without needing to install additional equipment and delivers cockpit communication via RS-232 (analog and discrete signals). This lithium-ion aircraft battery is TSO certified, lasts 8 years and features on-condition maintenance, saving you time and money.
