TB14
Advanced Lithium-ion Battery
The TB14 is designed for smaller, 28-volt fixed-wing aircraft. It delivers cooler and faster engine starts and ensures superior performance in extreme temperatures (-20°C to +70°C). The lithium-ion main ship battery offers on-condition maintenance and features built-in charge current limiting to protect your aircraft’s alternator or generator without needing to install additional equipment. The TB14 delivers intelligent cockpit communication via RS-232, analog and discrete signals.
