“Predator”, the new line of Lithium Polymer batteries from FMS, are manufactured with the complex LiCo Nano technology substrate. This process greatly improves the power transfer by making the oxidation/reduction more efficient. What this means is the electrons can pass more freely, less voltage sag with a higher discharge rate than a similar density lithium polymer (non nano-tech) battery.
For pilots it means stronger throttle response and more power for unlimited climb power.
