can i use SBEC or switching voltage regulator it to power raspberry pi and arduino together , connecting with a 3s 2200mah lipo? does the electrical noise of sbec create problem for raspberry pi and arduino? i dont want 11v volt battery gets wasted by heat while conversion to 5 volt.
what options i have to power raspberry pi or arduino (5volt) from lipo battery? also does BEC coming from ESC is suitable for such charging?
