More capacity per gram, meaning lighter models in flight, and longer transmitter duration
Almost no "self discharge", so your radio is always ready to go even weeks after charging.
Superior voltage performance under load, so your servos perform with more consistent torque and speed.
Faster charge time (as fast as 15 minutes!)

Each pack can sustain the listed max continuous current, and safely exceed it by 60% for 20 seconds.
Suggested max charge rate is 4C, which delivers 12-18 minute charge times, typically.
For larger models using the larger Rx packs and many or high-power servos, we recommend wiring the receiver for power with 16-18AWG silicone wire, and installing the supplied spare 3.5mm gold plug set, to match the Rx pack.
