How to set up a battery monitor & shunt

First step to set up a battery monitor

The first step is to make an actual measurement of the battery's amps. Before you do anything, We configure the capacity, If the battery is 200Ah we can put for example 250Ah, if it is from 100 We put it 150, Always a higher value.

Now we have 2 options, Fully discharge the battery up to 11.5v Yes, it is Lifepo4 o 12.00v Yes, it is Acid/Gel/AGM to set the monitor to 0 and measure during charging.

The other option is to fully charge it up to 14.6v, and measure until the voltage reaches the minimum voltage we have mentioned above.

This is done only once, Once we know the amps it has, We reconfigure 250 to the value he has given us, and whether it is full or empty we will only have to indicate to the monitor that it is at the 0% o 100% the rest will do it alone.

Manual TR16 Battery Monitor

Steps to set up the Tr16

1. Press center button “SET” until it says AH on the screen
2. Press it again and leave it like that until it flashes. At that time with the arrows we will put an amperage higher than that of the battery if it is of 100 we give for example 150.
3. Click again to confirm the change.
4. Press left arrow “V” for battery voltage to come out.
5. When in voltage, press and hold down the central button “set” He will put 0.0 (or any other if it has already been modified previously)we set it to 11.5v and press SET again to confirm.
6. Now it's time to discharge the battery to make a measurement. It would be to connect any consumption and discharge it up to 11.5v, You may not be able to keep an eye on it and it drops below 10.0V and the BMS turns off, If it happens once, nothing would happen, but it is not advisable to do it repetitively
7. We polish the right arrow so that the % of the battery at that moment we press and leave arrow “left” and he will get to 0.0%. If you can't because he has cut the bms, the charger is connected for a second to be able to do so, Although as it had been previously configured to 11.5V in principle it is set to 0.0% He alone.
8. Now it starts charging up to a voltage between 14.2 – 14.6v, If it is a Kepworth and it is done with the original charger it would be until the red LED changed to green.
9. We repeat the step “1”, And here we will see how many amps have come in.
10. We repeat the step “2” and we change the value we previously set to “real” that we have just measured.
11. Now if we enter into % should mark 100% if it does not, we hold down the right arrow for a few seconds until it does so.

For TURN OFF THE SCREEN just press the 2 arrows at once.

Connections

1- “B-” to negative battery pole.
2- “P-” Here we connect everything that I had previously connected in the negative.
3- “B+ / Green Connector” with a thin wire and a fuse from 0.2/0.5ah to positive. If the fuse is larger “1ah”, You will need a cable thicker than 0.75mm minimum.

Clarification: If the connection is not made correctly 1 y 2 we will observe how the voltage rises or falls and will not mark the charge or discharge amperage. And if you use a battery with a side connector such as a kepworth, the charger must be modified so that it passes through the shunt, If it connects to the side it will not mark anything and will throw the measurement out of balance.. The same as if it doesn't connect well.

* In the negative of the battery only the shunt cable is connected to the exception of whether they are placed 2 in parallel batteries that would be 2 negatives of the 2 together.

Manual Battery Monitor KG140F

First step of configuration

As mentioned above, charge it up to 14.6v or download it up to 11.5v/12.00 (according to battery type), but to make it simpler, I'll explain it “Downloading it” initially. So we click on settings and put a higher value than the battery, 150ah in the event that it was 100 (to give an example).

Second step of the setup

Now we indicate that it is at the 0% Having the voltage around 11.5V

Third step of the setup

We start charging the battery up to 14.6v or as far as our charger can go., 14.2.. 14.4.. when it is full, amperes will stop entering and we will see that in the application.

In AH. Rmn will put us the amps it has charged, In my case 84.080ah as you can see in the photo.

Fourth step of the setup

Now we just have to tell him that he is at the 100% and we would already have it correctly configured.

If we wanted to do it the other way around, you would only have to invert the percentages.

Fifth step of configuration

Adjust the real capacity that has been given to us in the measurement, we will put that data in “Preset battery AH Value” where initially in this example we put 150 now we will change it to 84 What was entered during the measurement?.
