??????? ?????, ????? ?????? ? ?? ???????????? ? ??????? ???????.Appears well made and works with a nice loud alarm but I would have prefered a higher voltage setting for that alarm. The ESC cut the power before it was triggered in flight. No issues there as I was just flying circuits waiting for the voltage to drop.Not useful at all for Lipos. The alarm only sounds when the battery cells are at 3.3 Volts. At that voltage the battery is already totally ruined. Typically a LiPo sould not be discharged below pcnt80 (around 3.75 volts). There are other cheaper products on this HobbyKing that have adjustable voltage alarm use those instead. This product can only be used to detect you have severely overcharged your battery.Works just fine. Isn't high tech, but worksJust got this today. Wow i cannot believe this works great. Loud and crystal clear lights. Great job hk.This low voltage buzzer is great and loud. The only problem is that it is fairly big and would take up a bit of space on a drone.HobbyKing Lipoly Low Voltage Alarm (2s~6s) reel low price on the marketSUPER LOUD beepers! Louder than the stock beeper on the KK2.1.5-HC boards!.
I use these on both my Tricopter and Quadcopters! Money well spent!
I just put a small piece of velcro on the back of this guy and stick it straight to my frame.Excellent to hear and see during flight if some of the cells are in bad condition. A quite loud sound is emitted and the corresponding LED light up when cells are below 3.3v, I would like to trigger at 3.6v but better than nothing. Peace of mind.Praktischer, kleiner, preiswerter Lipo-Warner, ist bei mir in den unterschiedlichsten Modellen im Einsatz. Kann man nur empfehlen um die Akkus zu schtzen.
