Install sur mon Trex 450, il m'a sauv plusieurs fois d'un mauvais pas; avec des Lipo diffrentes et des tempratures polaires, le chrono habituel ne suffit plus. Lorsque les LEDs flashent, il faut poser. Il me reste gnralement autours de 10pcnt de charge aprs contrle au sole.
Les LEDs sont bien visibles, je les ai dportes sur la poutre de queue, sur le support de hauban.

I bought two of them, both are working but on both the cell nr. 2 is meassured false by ~0.5 volt to less. Because of that, this things are useless... Sending back to china is not worth the money... Buy another thing...

No so much precise - it can handle up to 4s LiPos, but one (probably the first one from GND) behaves differently. It seem that internal filosofy is to take individual voltage from each one cell to measure and compare with thresholds - in case of first cell from GND it compare cell voltage as it is and in case of cells nr. 2,3,4 circuit divide voltage internally. Result of this is different behaviour for each individual cell. I have 3s LiPo and two cells are performing very good, but one is unprecise - even with discharging of battery indicator shows increasing of voltage to impossible values, e.g. 5.0V or even higher !!! Beside this fake measurement for one cell, it perfectly indicate all others. External flashes to LED behaves also differently from manual statement, if voltage of weakest cell is over 3.6V there is no external flash, in case of 3.5V if flashes 5 times, in case of 3.4V flashes 4 times and so on, in case of 3.1V it flashes once and if voltage is lover again stop external flashing. Keep it in mind :-)))

a must have if you fly in cold weather.
just came back from a flying in 35 degree weather, and the LEDs indicated low battery within about 3 minutes, when that battery usually last 6-8 minutes. saved my planed!

I like the diodes bright flashing but unfortunately this indicator reset itself when try to light the diode. It seems that the diode/s need to much power to feed. So when diode installed its useless. But you have lightweight voltage meter anyway :) Next I will try some with buzzer.

super systeme de control. Permet d evaluer rapidement le niveau des accus lipo en vol. La luminosite est correct mais pourrait meilleur. Tres leger. Tres bonne idee de deporter les led pour les placer hors du fuselage.
Je le recommande
