NOVAK NE5474 Smart Boost. 3.7volt to 6volt for receivers.

Boost a single 1S LiPo 3.7volt up to 6 volts to supply the receiver and servos.

6 volt,  3amp output

With on/off switch (Note: Speed control switch must remain Off)

Weight: 28gm

allows nearly any brushless or brushed speed control, receiver and servo to run on 1-cell Li-Po. This technology expands racing opportunities for many drivers by reducing racing expenses and giving drivers the chance to race on smaller tracks.

The Smart Boost increases the 1-cell Li-Po battery pack's voltage from 3.3V - 4.2V to 6V, ensuring that the receiver and servo receive a full 6V/3A power throughout the duration of a run. This allows the electronics to operate at their optimum levels. Additionally, the Smart Boost gives you the ability to run a 1-cell Li-Po cell with the same ESC, servo and receiver that you would normally run with any 2-3S Li-Po or 4-7 cell NiMH battery pack, including all of Novak’s brushed or brushless speed controls.

Not only electrically powered cars can benefit from this technology. The Smart Boost is also compatible in nitro vehicles. Installed between a nitro vehicle's 1-cell Li-Po pack and receiver, the Smart Boost can boost a nitro vehicle's voltage to 6V/3A to power the receiver and servo.

By increasing battery output voltage, the Smart Boost allows users to use any radio receiver in single-cell applications, including spread spectrum radios. The usual voltage fluctuations that cause reception issues with your radio using 1S Li-Po or 4-cell NiMH battery packs are no longer a concern.
