Are you troubled by the following issues? How can l feel at ease going out without a good electricity meter It's really annoying!
I don't know the power consumption of the secondary battery
Unable to accurately know the actual power
consumption of the battery
The original instrument panel is inaccurate when replacing the batter
After replacing the battery, the instrument panel of the original car is based on the previous battery display
Travel concerns
I have no confidence in my heart!
don't know how much electricity was actually charged
Is it fully charged?
Worries about having multiple batteries at home
I can't distinguish whether there is electricity or not,so l'm afraid of wasting it if l throw it away
Battery maintenance
Convenient and practical
Wiring diagram
Note
Battery capacity testing is the cumulative process of discharge current over time, which requires a certain amount of time. The specific amount of time depends on the size of discharge current; Before testing the capacity, the full charge voltage and cut-off voltage should be pre-set according to the specifications of the battery used. After fully charging, the discharge test should be carried out. When the remaining power is displayed as a space, it indicates the end of discharge, and the displayed capacity value is the battery capacity.
Remaining power
The remaining power is displayed by percentage and battery symbol, with a total of 10 cells represented by the battery symbol, each representing 10% of the power.
The remaining power is calculated based on the current battery voltage value. Before testing, the full charge voltage cutoff voltage should be pre-set according to the specifications of the battery being used; Every voltage=(highest voltage - lowest voltage)/10

Ok, positive things first:* i like the easy USB-Connection and the Housing of the shunt, even if the positive wire connection was missing* the display is nice and easy to read* the ampere and voltage seem to be quite accurate in my case* smallAnd now the points which i find quite dissapointing:* the State-Of-Charge (= Battery Level) is only calculated by a (configurable) voltage. Which does not make sense with Li-Ion or LiFePo type batteries* the display does ignore the current flow direction, so if you charge your battery it still counts as "discharge"All in all this makes it pretty useless as a "Battery Monitor" in my LiFePo based project. Maybe it does make more sense in a AGM battery project.

There is a lot of information but I need a magnifying glass to read it

Only bad thing I have to say is item was missing the screw that holds the positive wire to the shunt. I had to go to a hardware store and find a replacement. Other than that, it was extremely easy to install and results match my Fluke meter. Recommended. I used in a battery box for Ham Radio doing POTA, Parks on the Air. 73 de W6OBB

Like lots of voltage, current & charge of battery and load. Current sensor could be smaller for my application.

I bought one of these and it arrived without the set screw used to fasten the voltage reference wire ("B"). I returned the monitor and bought another: same thing. I bought a set screw assortment: they were all too large (M3 thru M8; I am guessing that the correct screw is a M2 or M2-1/2, if it's metric at all). The assortments cost as much as the monitor, so I returned the second monitor and bought a different brand.Fast delivery, though! Maybe slow down a bit and make sure everything is there before you box it.

El producto en sus inicios se veía de muy buena pinta, al instalar todo correctamente me di cuenta que tenía un error de medición considerable en cuanto a la corriente se refería, pude darme cuenta que había más de un 20% de consumo que no estaba registrando pero decidí ignorarlo ya que en voltage marcaba 0.1 volts de diferencia y me pareció tolerable y decidí conservarlo, luego después de menos de dos semanas de uso , la pantalla se muestra manchada y es poco legible , cabe aclarar que el producto no fue mal manipulado ni golpeado ya que desde su instalación en mi banco de batería solar jamás lo volví a manipular desde que fue instalado y funcionó bien durante unos días. Parecía demasiado prometedor y de buena calidad, pero en mi caso no lo fue. Tomen en cuenta.

So far so good, doing is Job very good.Easy setup not as many others with shunts. On the market i think this is the best for quality and money. Has a lot of functions. Hope wil last long
