Novak Smart Boost 1-Cell LiPo Step-Up Module.
This looks like something I might be investing in soon. New from Team Novak is the Smart Boost 1-Cell LiPo Step-Up Module. It allows any brushless or brushed speed controller, receiver and servo to run on a 1-cell LiPo. The Smart Boost increases the 1-Cell voltage from 3.3v to 6v ensuring the receiver and servo receive enough power. I have been thinking about trying out a small lipo receiver pack this year to drop some of the weight and bulk from a normal pack. If I do, I’m picking up one of these!
