3DR Power Module Accuracy

How accurate is the 3DR power Module?We set our Mission Planner warning to go off at 13.5 v on a 4s 8000mah battery.We had only used 25% of the battery and cruising draw was just 5A, but we were getting low voltage warnings. When we knocked the throttle off, it went back up to 14.7 volts.IMO cruising at 45% throttle and pulling just 5amp in cruise should not have pulled the voltage down that far on a fairly full battery.All config settings for battery size and voltage were seemingly correct.CheersMatt

  • Depends how good your battery is. Is it a new pack? What sort of condition is it in? Packs that have a lower C rating will have their voltage pulled down further than higher C rating packs. Packs that have been consistently over discharged or have puffed from being left fully charged will also sag a lot more under load than packs in good health.

    BTW. What are you flying where you can get a cruising current of only 5A? Even my F450 is up around 20 or so!
