5-Cell RX Packs offer many advantages. It allows servos to turn faster with more torque. More importantly, it offers extra safety margin. When a cell in the RX pack goes bad, you still have four cells to operate the radio system safely. Most servos and receivers are designed to operate with four alkaline batteries, i.e., 6 volt. However, the voltage of a freshly charged 5-cell pack can be as high as 7 volts. As a result, it could cause jittering or permanent damage to servos and receivers. Century's 6V Receiver and Servo Batter Regulator provides a turn-key solution for this situation.

It is very easy to install this regulator. Simply plug it in between switch harness and receiver. That's it! If you plug it between RX pack and switch harness, it will work too. Except. you won't be able to charge your RX pack from the charging plug and it will drain the RX battery slowly.

The regulator is rated for 10 watts of power dissipation. This means the current capacity decreases as the voltage increases.
