The 1S DC-DC BOOSTER is a DC-DC power booster module which can draw power from a 1S LiPo battery, then boosts it to the voltage level (6V) that suits the receiver & servo and provides continuous output current up to 3Amp.

It is mainly applied in 1/12th / 1/10th on road scale RC vehicles. 1/12th scale cars usually use a 1S Lipo battery, and the BEC in an ordinary speed controller is a step down. In that case, the BEC output voltage will be lower than 4.2V and cannot meet the power demand of the receiver & servo. It is necessary for a 1/12th scale car to run with a purpose-built 1S ESC with a built-in DC-DC booster or external receiver battery if the speed controller doesn't have a built-in DC-DC booster. Things will be different after adopting this booster- the receiver batteries can be abandoned and users will be free from charging and maintaining the receiver batteries. 

• Input Voltage: 1S LiPo or 3-4 Cell NiMH
• Output Voltage: 6V
• Output Current: Continuous 3A, Burst 6A
• Dimension: 28.0mm x 26.8mm x 11.8mm (L x W x H)
• Weight: 10.2g

Attention:

For ESC with the "built-in BEC" function:

Users need to cut off the internal BEC output first. To do this, disconnect the red wire between the speed controller and receiver as shown in the picture below. Then connect the positive & negative poles of the input end of the 1S DC-DC BOOSTER with the positive & negative poles of the battery. Plug the output end of the booster into any unoccupied channel of the receiver last.

For ESC with no built-in BEC function:

There is no need to make any change to the ESC except for connecting the positive & negative poles of the input end of the 1S DC-DC BOOSTER with the positive & negative poles of the battery and inserting the output end of the booster into any unoccupied channel of the receiver.
