The case against BECs

by | Sunday, September 25, 2016 |

Background: ProModeler servos are rated at 7.4V (nominal voltage for a 2S LiPo pack under load), However, it's widely known that fresh off a charge, the output of a 2S LiPo may approach 8.4V. Thus, it's not illogical to wonder; is it OK to use 8.4V when setting up the BEC? In fact, we're often asked variations of this . . .Q. Is it OK to set the BEC output-voltage to 8.4V with ProModeler servos? A. The short answer is yes, but we recommend using a battery instead of a BEC.Long Answer: Lots of...
