I have a Tekin RS that I'd like to repurpose rather than buy a new ESC that has a built-in booster but the local hobbyshop only has small Lipo packs to use as a receiver pack and I was hoping to be up and running this weekend.

Any advice you could provide would be greatly appreciated!

Cheers,

you are correct that the ko servo and receiver can tolerate the 2s lipo voltage but NOT the tekin rs.

you need to add a booster to the 1s battery, or use the 2s life battery, or do the BEC wiring trick on the picture above.
