Thread: Battery warning level F450

    Battery warning level F450

    Hi,

    I'm using a 3600 3C 11.1v Turnigy battery with my stock Naza DJI f450 GPS with stock 8" props, stock gains etc, with a gopro underneath.

    What should the minimum battery safety warning voltage (when the red light starts flashing) be set to?

    Thanks,
    Chris

    Thanks, I've given that a read - much appreciated.

    Regarding calibration - is it possible to be accurate without using a multimeter?

    I just had a quick flight, landed when the red light on, plugged into computer, checked calibration - it says 11.39 on the DJI software, and 11.5 on the TX (DX8 with telemetry), so based on the TX voltage alone, is it OK to adjust the calibration from this?

    From default it was set to:
    First level No load: 11.5, loss 0.7, loaded 10.8
    2nd level No load: 11.1, loss 0.7 loaded 10.4

    So I guess my question is how am I working out my line loss here? These are almost new batteries (5-10 5min flights on them)

    You have two choices, either a meter which should be pretty accurate or using this (GT Digital Battery Volt Meter) https://www.gothelirc.com/shopdispla...ry+Accessories for $6.00
