Spanningsmeter voor batterijcapaciteit, met alarm en externe temperatuursensor, temperatuurmeter van 0-179 °F, 12 V, 24 V, 36 V, 48 V, 60 V, 72 V, 12 V, 24 V, 36 V, 48 V, 60 V, 72 V

I saw som reviews saying you can’t turn it if or the battery gauge is in accurate. And it if the box that may be true but all you need to do is go into settings make the adjustments and it does exactly what you want accurate and customizable. The only pro had was the power wire broke off while I was monkeying it around during installation. I was a little too rough with it it’s very delicate in that regard. I had to solder it directly on board and all is working perfectly now.

Es muy fácil de montar. En mi caso en una bicicleta eléctrica; uno de los datos más importantes en este caso es saber en todo momento cuanto queda de batería, para saber cuando volver al origen. Mi batería a plena carga tiene 52.3 V y a 42 V el controlador corta la alimentación al motor. Llegué a 43 V y este medidor aún marcaba el 100% de carga. Es una chatarra que no aconsejo a nadie que compre.Aparte, a la luz de día no se vé la pantalla para nada. Un desastre.Me veo en la obligación de corregir mi anterior comentario, ya que si no funcionó en un principio, todo fué debido a que no lo ajusté a como lo indican las instrucciones. Una vez hecho, y ajustado a batería de Litio, y tras ponerle los límites superior e inferior, lo he probado esta mañana y funciona bien; el gráfico de la batería muestra el porcentaje de carga que le queda y aunque no es perfecto (lo digo porque encendiendo-apagando y volviendo a encender, se aprecian unas pequeñas variaciones que en mi caso no tienen importancia.Por el precio que cuesta, no se puede esperar mayor precisión. Espero no haber puesto a nadie en contra de comprar dicho instrumento.

Perfekt

This is a really good product that is packed with features, but it really pays to spend the time to set it up. Most of the bad reviews are from people who haven't done this.I'm a motorcycle world traveller and because I have to edit YouTube video's on the road, I have various power option including solar to keep the cameras and laptop running. It is important that I can keep an eye on my charge levels. This meter has proven to be accurate and has an adjustable low voltage alarm which saves me from waking up to a dead bike in the wilderness.Settings include:Battery type(Lipo, LiFe, Lead Acid)Number of cells/VoltageVoltage Range(To customise the % bar graph to your setup)Temp unit(Celsius or Fahrenheit)Over temperature alarm(Can be disabled)Time to sleep(Can be disabled)Voltage readings are accurate when checked against a fluke DVM and you can always re-calibrate the unit with a 20v supply(See the manual)The unit draws a measly 8-10mA with the backlight on and 15-20uA in standby mode.All in all this ticks every box for me with the added benefit of a temperature sensor so I can brag about how cold it is while I sleep in my hammock.Add a sub to youtube/FoxADV to see my future review.Google "GY19171.pdf" to find the user manualFoxADV out!

piccola dimensione ma lettore concreto e affidabile e di facile installazione
